A new approach to Retopology 

This add-on is now released. It's name is Final Topology.

Not the hero we deserve, but the hero we need. Doing god's work!

I've wanted this for about 25 years - Thespline tools in Corel Draw do this in 2D and I've always wanted this ability in 3D as, especially with Blender's loop selection, you'd be able to drop mesh desity easily without hours of pulling points around. Making computers do the work, this is what computers are for! :D

I am so excited to see advancements coming to retopology! it always feels like retopology needs a bit more love in blender.

omg it's amazing! I've been looking for tools like these for years, and they finally exist haha

Dude yes. We have needed this for so long. Thank you!

The tools at 14:00 and 15:00 should be built into Blender by default, I've had both of these issues in the past week alone

tbh, there are a few things I just never had the patience for,... 1. UV unwrapping 2. Retopo 3. Rigging.... if these three aspects could be simplified into processes that don't take hours on hours to do,.. I think my creativity in blender would just explode.... You guys are all amazing!

Man… I would be clapping and cheering from the start! Man, that’s a before and after in retopo!!!!! 👏👏👏👏👏👏

What A Legend only hardcore Retopo people know how good this is

the closest i've gotten before this is using the multires modifier instead of subdivision. You can apply a shrinkwrap after it, and have the multires conform to it

Can't wait to see more of this, thank you for the effort in this tools

This looks fantastic Vilem! I've been doing a lot of retopology lately and cannot wait to try this.

Just, awesome!

Hero! THanks for developing this!! This is going to be a game-changer for the Industry! SO excited

Feels awesome to see a presentation from a Czech person at Blender conference. Probably because of how small of a country we are, it makes you really realize how diverse the Blender community is while they all share passion for the same program.

This is actually so necessary. In retrospect, it is true that when I tried to retopo my models, although they looked neater, they also looked a lot softer. I thought it was just a symptom of using less vertices, but actually you tend to lose detail in cavities and parts that stick out, so you end up adding new geometry after the fact. I notice this a lot when retopoing eyelids, nostrils or ears.

such a simple yet a brilliant addition I've wanted this for as long as I've known subdivide modifier and it's been only guesswork and manual work from my side

So awesome! 🎉

I can't wait. It's magical

I'm jumping for joy!!!!!!

I have had this exact thought before, glad someone put the work in to fix this issue

This is really cool. And as he stated, it gives you better topology, not just easier. I believe when machine learning tools are created to do retopology for us then it should be trained on this type of topology which follows the original surface better.

i just did my first character in university and man retopology is no joke i felt like i was doing a big freakin puzzle the whole time lol im really excited to see new technologies and ways of retopo because at times when things are going well it can be relaxing.

can't wait to try it, very cool work!

yes please!

Mindblowing!

Thankyou blender!!

we need this NOW. awesome that finally someone found a good solution!

Thank you very much Vilem Duha for sharing! and will be a cross-generational function for all artist, but I want to express my opinion. There will be another need that has been ignored in topology. Topology is also a process of reducing triangular surfaces, so the artist While re-topologizing, we are also thinking about which details require topology and which do not require topology. This is equally important, and I think it will provide some food for thought on how to improve this feature. Thanks again!

I love when humans use their intelligence towards art ❤

This is insane, can't wait for it to be released!

Nice to hear F2 mentioning to its author. You can find lots of interesting F2 using videos on my channel. As far as I remember, there are no tools that reconstruct original unsubd shape, but there was discussions around that.

wow, looks great

amazing bravo cheers' mate

Great !!!!

This is a game changer. I have yet to practice any retopology, but understand how it works and different ways to approach a model, but this is really a game changer. Never thought of taking an approach like this. Good job, can't wait to try it out

This is awesome

just use inverted smooth modifier, it is easy.... it is exaclty what preserve initial surface, and in fact after retopology you mesh is just smoothed, SO, JUST USE SMOOTH, IT IS NATIVE MODIFIER just set -1. there is should be video about nice fast tools to generate topology patches easily, like standart blender "fill grid" but without it's bugs. all i need is markdown system, and automated filling, it is more than enough.

This looks really good. I would use this a lot.

Wonderful work, interesting new concept. Cant wait for a release.

This is Absolutely Brilliant, well done, cant wait for its release

WOOT! ty

More mesh analytics tools is always welcome.

Interest is piqued ... times ten!

this is amazing, this is something that has needed to be done for a LONGGG time for the whole entire 3D industry. Thank you

This is huge!

完美的，非常期待

ftr, the multi-res modifier has a similar feature. i think it's called "apply base." you just have to apply a shrinkwrap modifier beforehand. however, that feels much more destructive and moreso something you do at the end of the modeling process. something more real-time would be awesome and just feel better.

amazing

Vilem! Super cool!

I love them showing off the BSurfaces side-by-side comparison and having it actually be significantly _slower_ than the standard approach 😆

Great Job

This is seriously cool tech. I want that addon :) !

8:55 exactly that is the reason why I never use automatic stuff for retopology and do it all by hand, even when I have used retopoflow, funny enough I mostly forget that I have it, I jump out of it and adjust the vertex again so that they fit better ^^

I can’t wait to play with this!

well, well , well ....❤❤❤❤❤❤

That's really cool. And it's most likely that nothing like this tool exists anywhere.

hopefully it's fully added

well, that's exactly what i was poorly trying to achieve with a combo of remesh and shrinkwrap... on a computer not connected to internet. Now i'm affraid of youtube's algorythm, but still glad it sent me here. great work man !

Give me a motivation to sculpt

very cool

@Blender I wish Blender could change a settings in snap face when retopology, it's annoying to see your extrude face going to far of where you wished it to be, but it could be better if Blender use a snap face with a combination of this direction of Y, X, Z to automatically snap with the exact direction of your extrude

nice!

This is incredible !!!

I know there's already super convinient retopo tools outside of Blender (Zbrush having my favorite), but this should've been implemented into blender a long time ago. Still a great feat regardless.

Amazing work 🙏

I’ve done retopo in Maya, Zbrush, and Modo. I’m pretty proficient with Blender now and love it, but retopo seems so clunky to start up in Blender. I replaced modo with Blender for modeling and every day use, and haven’t really messed with Modo. I really liked how modo had a retopo tab, it was intuitive.

in this and that menu, mouse click twice, a popup window shall appear with the perfect tools you where always looking for... it exists as of blender 2.6 - - THAT IS SO BLENDER!!

-> It is like basically wanting to clone the high poly mesh so perfectly in a low poly form that it captures each curve as it should. So i can see the issue and the solution he presents. -> Outside of the box thinking... Or A Texture Bake system for low poly, so we don't even need to sculpt them in high poly... A Low poly texture bake system that can have any data for textures. ( scales, what not. ) based on a data bank and catalogue of thousands of models made by users. You set the parameters. ( Dragon model textures. etc. ) And the system randomly bakes textures of those categories unto your model. Having scanned your model. And the user can keep doing the process until he gets a happy result. Low Poly, baked with high res textures without ever even going into sculpt mode... Basically like those special paint bath where they coat art on an object by dipping said object carefully into the liquid and than taken out. Can't you make the retopo mesh smaller than the high poly sculpt, so it fits within it perfectly. Then using face direction or something like it you tell Blender to bake the outside face of the high poly to the outside faces of the low poly inside the high poly sculpt. So you revert the face direction of the high poly to the inside, so it projects those textures down and shrinks it evenly on the low poly model. So that instead of trying to capture larger textures on a polygon count too low to really measure them, we shrink the textures down to fit on a slightly smaller model... Or something along those lines. We essentially try to adjust the low poly to capture the bigger elements, rather than casting the bigger elements on a slightly smaller model.

Just use the shrinkwrap and multires modifier (which uses displacement and can then be baked to displacement and normal maps). There are plenty of tutorials for this.

looks really good, however would like some more auto retop tools, an update to what quad remesher can do. 3Ds max auto retop is great, and with advancement in AI now retop should be a thing of the past

Isn't this why we use shrinkwrap modifier and the multi-resolution modifier? Really cool area to explore.

nice 😮

14:46 thats a literal game changer for my workflow

We’re do I buy! Now here swipe my card Mr 😂 quickly before my sculpture runs away. Funny enough I know it’s not fair to you Og blender users because you been on it for years! And needed this and here I come along and learn blender in a year and then all these helpful tools come out… I know it’s not fair but at least we all win in the end.🙏🏽👍🏽 IS IT OUT YES OR NO?

I guess its not a feature because it was never really needed. In the regular pipeline, you often project which solves the problem automatically and when it comes to hard surface retopo, you usually don't want a 1 to 1, you want an improved shape (And displacements maps are a thing too). The freeze mesh tool does seem really useful. I'm for sure trying it out, maybe it will feel nicer to work with, only worry tho is that it will end up being laggy especially for really heavy meshes. If it doesn't work out, well Zbrush still exists.

maybe this can get even better for normal map baking, imagine an accurate offset slider, for cages with no colliding surfaces

This is an awesome development for organic retopology! Is this tool available now? How can we get it?

absolute legend. he deserved nothing less than a standing ovation.

I know that the decimate modifier has an unsubdivide option but i dont know how well it works. You might be able to simulate the inverse subdivide by doing a subdiv, shrinkwrap, decimate combination

He explains the problem well, which I hadn't thought about before, but I don't understand his solution at all. Is it a free addon? Paid addon? What's it called? Does it just show how your retopo is off or does it fix it for you? How do you use it???

Make it standard built in in Blender. Otherwise just another addon. Just like that Set flow addon. Just work together with the authors to built in inside blender

When is the release? What will this tool be called? It looks very promising

So would this cut down that 1-2 hour thing to what like 30 minutes? I'm new to sculpting. never really retopo'd yet though as i 3d print stuff.

In my humble view, this kind of remeshing should become default. Perhaps not by force, as it is bound to take extra computation, but it has so many use cases.

I hope you (the speaker) can do a more technical deep dive video about the optimization algorithm when you release this.

forgive my naïve question but doesn't this already exist? didn't the original subd paper suggest any volume preservation methods?

So when we can try this tool? 😊

Damn and I just bought quad remesher

Why not finally add the ability to start retopology with the click of a button, without selecting bindings, modifiers, etc.? And I want to ask the same question about the possibility of setting a temporary color for polygons without changing the material settings?

There is one in zbrush its called projection.

Let's not fail this artist guys, you know the consequenses!

I feel like this is a dumb question, but why not just use the shrinkwrap AFTER the subdiv? Wouldn't that snap the subdivided geometry to the high poly surface, instead of snapping the pre-subdivved mesh to it? There's still some cool functionality here regardless, but I'm really curious why he's completely glossing over this option.

thats genius

A mí me gustaría que en la Re topología hubiera muchas más opciones y que de alguna forma fuera más rápida y precisa porque, aunque funciona, es muy tediosa y lenta. Yo hago modelos de criaturas y la re topología me fastidia, también me gustaría que blender mejore un poco en términos de rigging y en la optimización en cuanto a la cantidad de vértices en modelos. Pero a lo que realmente le vi un problema y dificultad es a la hora de crear un Normal Map, es muy complicado en EEVEE y de la otra forma igual, me gustaría una opción que te permita crer un mapa de normales con un modificador y que este se aplique después de aplicar el modificador, o crearlo como una textura procedural similar al Bump o displacement, ayudaría mucho con los novatos que recién van empezando y quieren conocer la re topología y los normal map. (Esto no es una crítica es una sugerencia para una futura actualización, por ejemplo, la futura. 4.5)

Oh... my God...

I wonder if AI in the future will allow for instant accurate retopology, that makes the shape of the model accurately. I also hope AI can make UV mapping less of a nightmare in the future

this exist in maya since long ;)

How is the end result from this method of snapping different from the method used in the video ,”Projecting High Res Sculpt into the multi res modifier in Blender” uploaded by Louis du Mont? If this add-on is more accurate then great! Would be nice to see a side by side.
