Let's explore the controversy about the use of quads vs tris and nGons. Not only for #b3d Blender users. Mesh checker addon: pistiwique.gum... Original mesh: www.dropbox.co...
Nice tips. By the way, when I'm doing a planet, I'm also using a cube instead of a UV sphere. Just the standard cube, then I give it a Subdivision Surface modifier with Level 4 or even 6, then add a Cast modifier with Factor 1 to make it fully spherical. For the planetary texture which is usually a 2:1 ratio image, instead of using UVs for it I set the projection of the Image Texture node from Flat to Sphere. Et voilà, perfect planet 😁 For the Texture Coordinate you can either choose Generated or Object, the only difference it makes is which way the "front" of the texture faces, in X or Y direction.
@@BlenderBob Yes, I know the extra objects and have them enabled... I should have mentioned I do it this way with modifiers to keep it procedural. Of course when I want to apply them I could as well use the round cube with the "Quadsphere" preset. Although for a destructive workflow I think it goes quite fast with a default cube as well: Ctrl+4 to subdivide level 4, then Ctrl+A > Visual Geometry to Mesh, then Tab into Edit Mode and Shift+Alt+S for the To Sphere tool and dragging the mouse until it reaches 1. Just a few quick shortcuts and two mouseclicks. Fast and easy.
Thank you for these tips and workflows. I've been doing 3d for 15 years, and I still have a hard time keeping good topo. It's hard to remember all these guidelines.
Wow thanks for making this! Learned a lot, absolutely a masterclass. The reason why it's important to have evenly-spaced topology finally "clicked" for me. I would've been doing pushups for giving you a model with holding edges before.
If you select an edge, than an other 2/3/4 etc loops from it. Control, shift +selects the next one 2/3/4 etc loops from that. In your case doesn't matter to click 8 times, bit with more dense topology its usefull.
In real time the lighter the better and triangle is the norm for accelerated GPU but as you say for exploding simulation or deformation in houdini or other it's a big no, they probably some trick to made destructible objects with muti low poly mesh collision depend also if the engine use some LOD ...
just wanted a to watch another short BlenderBob video... and then found the best, most comprehensive retopo guide on yourtube ... Next time, please, put a warning sign that this is not a 10mins blooper.
Hey Bob, great vid. I have a question and I can't really get answer to it. I'm working on an animation series, which will be rendered out with a GPU render engine, Octane. 80% of objects won't be highly detailed, but there will be lot of them. Which type of topology method would be more hardware friendly? As you mentioned, triangles doesn't necessarily mean less faces, but as game engines work with triangles and are calculated by GPU, would it mean that it will be better to use triangle meshes when rendering with GPU? I'm trying to figure out what would give me better economy at GPU memory and render times, Thanks!
Octane is a path tracer so it doesn’t render like a game engine, even if it’s GPU. So it won’t matter much. The important thing about path tracers is that everything fits into RAM memory, including textures (which is usually the problem with Cycles as it doesn’t do mipmapping. Not sure if Octane does.
There's no fixed method! All of them are good for a specific case. I done them all in all ways on all tasks possible with 3DCGi. When I was young I pursued the perfect topology and as professional I was forced to use all the crap imaginable... and even that crap has it advantages :) The key is know exactly were and how to use each method.
@@BlenderBob Yeah, yesterday I was going to sleep, so hadn't the chance to see it from start to finish, but I will! I've added the video to my Sunday list. At Sundays I take 3 hours to study and this one is on the list! Thanks for your work and time!
@@danielgroenewald3006 What one dreams to do as a aspiring 3D artist is not what one ends up doing as soon we get paid for it... specially when everything has to be modified 50 times before approval... ...and when it finally gets approved one already can't stand the darn thing anymore! One just want's to get rid of it! 😆
tl dr; not gonna subdivide? you don't have to care about topology/quads/ngons if it renders well. don't worry about topology unless you have to worry about topology.
It’s not always about if it renders well or not. It’s also about displacement maps, simulations and 3D texture painting. All three versions render well.
