Wrinklers....

Sqworm Yes, we all know who we’re talking about.

Chris Jones Huh?

😂😂

ITS A SQWORM

its great for skin deformation in faces, and clothing.

child

@@fireball75677 uhm.. Ok higher being

@@antonkoekemoer4136 lol

😭😭😭 dude

Girl you thirsty...

🥵 ok chill ma’am

That’s so cool! It makes a lot of sense that they’re being used out there, I just wish they were more accessible to freelance artists.

Question. Are tension maps used real time in games, or are they best used to bake better animation blends?

Ah yes, Chris Jones. yea boi

Sqworm

yes, the addon can output vertex groups, these groups can be combined with manually painted vertex groups to get the adjustable effect you want.

kind of! bump maps dont displace vertices and are black/white, displacement maps do displace vertices but are black and white, and vector displacement maps displace vertices in 3 dimensions so they can do things like create a hook that comes out of a surface.

Actually that’s my worm! I recreated his worm with the tension map addon.

@@kextnext wow, nice blender knowledge!

But it's very common to triangulate your meshes before exporting

Harder to model, easier to develop a game engine for.

no)

the only information needed when using this in a game engine is variation in length, typically 3 sets of normal maps are used. relaxed, compressed and stretched, these are then blended using the information gathered from relative edge length...

@@dixie_rekd9601 where do you get relative edge length from in a standard rendering pipeline?

@@maxmustermann3938 I dont know TBH, lol I dont often work with game engine shaders, however once you DO get this, its the only info you need for a tension map, since the shader doesnt need a vector from each vert since tension maps dont work directionally, they only work to blend between a few different normal maps rather than trying to create a normal map on the fly.

@@dixie_rekd9601 yea, my comment was about how one could potentially get that info in a game engine, but I am not sure that what I described would work. You'd usually use rigged and skinned meshes and thus you have a transformation matrix for each vertex. Rasterization pipeline focuses on vertices, so you really don't have neighborhood info like edges if you don't manually make sure of that. Which is why so thought just using the vertex-local transformation and grabbing the scaling portion of that might work. This way you essentially generate your "vertex colors" on the fly in a vertex Shader without the need for any of that stuff. Could work but I really don't know lol. You do get more than one scale, as in one scale per axis, which I guess you could just combine into a single scale or somehow make use of for whatever you want if you can come up with something

Not sure. Just a change in pace from my usual content, I guess.

You really have to understand transforms (in matrix form, or in vector/quaternion form) and vector spaces if you want to do any 3D, be it in a game engine like Unity, Unreal, or a raw graphics API like OpenGL. You just can't escape them. Good news it that once you understand, a world of possibilities opens up :)

@@VirtualMethod i dont think you need to understand matrix to use unity, ive made 5 games and ive only used matrix once in one line of code out of tens of thousands.

@@XxxTheGoldenApplexxX Not talking about Matrix4x4, but about Transform, which you have to use in pretty much any game (unless it's extremely simple). Once you understand things like world/local space, converting data between spaces, transform composition, rotation order, etc matrices are just one way of representing them. Imho what's difficult is not understanding what a matrix is, but how transforms work. Once you can juggle transforms, putting them in matrix form is easy: get the identity matrix, slap the orthonormal axis in the first 3 columns (or rows, if using row major) and the position in the fourth, that's it. Projection matrices are a different beast, but dealing with them directly is much more uncommon.

@@VirtualMethod i dont think you need to understand transform as a matrix in unity. Its just 3 variables, one for each axis. Also what kind of game mechanic requires you to convert transform from local space to world space? Also dont unity already has specific variables for both local and world space? Idk its been a while since ive touched unity.

@@XxxTheGoldenApplexxX " i dont think you need to understand transform as a matrix in unity. Its just 3 variables, one for each axis." Nope. A transform is a position, a rotation, and a scale, so 10 variables if the rotation is in quaternion form (3+4+3). 9 if the rotation is euler angles. 16 in 4x4 matrix form. With 3 variables (one per axis), you only get a position. "Also what kind of game mechanic requires you to convert transform from local space to world space?" Something as basic as shooting in a FPS: the direction you shoot is "forward" in the character's local space, but you have to convert that to world space to shoot (as the bullet is typically not parented to the character). Same for strafing, you move "left" or "right" in local space, but you need to convert these to world space. If you know about matrices, and how they're built, you can get the local axis expressed in world space from the character's matrix first 3 columns/rows, though. Another typical example is a character standing in a moving platform. Usually you'd want to convert data from character local to platform local, so that's character->world->platform. Can be done much more efficiently by multiplying matrices together to get a "character to platform" matrix. Any non-trivial UI: you drag an icon from one panel to another (think inventories) and you need to convert the click/release mouse positions from screen space to panel local. Many camera setups (arcball, third person, etc) also require you to deal with these. My point is that in all the years I've been making games there's not a single game where I hadn't had to convert stuff between vector spaces. So if you're serious about making anything 3D matrices are a extremely valuable and powerful tool, investing time in them is totally worth it. If you write your own shaders or modify the render pipeline (not everyone needs or wants to, but many intermediate-advanced stuff requires it), matrices/spaces are everywhere as you need to understand object, tangent, world, camera, and clip space. "Also dont unity already has specific variables for both local and world space?" For convenience, Unity gives you local and world space rotation/position for each transform. But that does not help with converting to a different local space (as in the platform example), and in many other cases. Once scale is involved, things get much hairier as composing rotation and scale gives rise to skew (which is generally undesired) and doesn't help there either.

a glossiness and roughness map are inverts of each other so he may as well have showed a glossiness map

@@aonodensetsu they are still part of a completely different workflow

@@IPpainting they are, but the look exactly the same in the final render since their job is the same

millions of verts is easily rendered during gameplay in a modern game engine, however if every object were using displacements instead of normal maps, the number of verts on screen would be nsane even for the highest end graphics cards. good luck throwing 15 billion verts around at a high framerate, this is why hardware tesselation was developed, you can get adisplacement from the GPU without needing to internally render every vert. but hardware tesselation and displacement maps are very different even if they look similar.

its what we mostly use it for, free detail

Yeah no that's a stretch Enjoy your nightmare CGI hentai though

It’s a worm ;)

because it was heavily integrated into "blender render", the old pre 2.8 render engine... its a shame its not been reintegrated but with the new versions of blender coming soon, it will be easily possible.

@@dixie_rekd9601 Thanks for the explanation, and I really hope so that'd be really useful even if in very specific scenarios. The more tools in the sandbox the better sometimes. That being said I am proud of, and appreciate the Blender foundation for making progress and focusing on organization and quality over pure creativity which it still has plenty of. If only Nvidia didn't crowdsource the funding in retrospect by playing the market after creating Optix.

lol

nope, blender 2.79 and earlier had tension maps, even if it was a little used features rarely mentioned with basically zero documentation. Edit, it was called stress and was a kind of texture space

@@dixie_rekd9601 Rly? i only knew about it after the addon

@@kendarr yeah it was super confusing to use though and while it could get the same effect as tension maps it was done entirely differently

Lol yeah, this was made before geo nodes, I’m so glad blender is progressing as much as it is!! Hopefully one day it gets to the level houdini is on but it’d need to be ALL nodes for that

It’s created by Chris Jones, who I’ve referenced in the video. As for the thumbnail, I recreated it myself using the addon, so it’s my image.
