This is by far the most interesting video I’ve ever watched on KZfaq. Disclaimer: I’m very high.

Hey where did you get this model? thanks

Th 8K maps are quite a catch, but other than that, amazing work!

Good point. Any idea how you could use a best fit to make it so you have a few pre defined cards that it uses that can be assigned to those planes that best match? You know the shape of most clusters so you can probably reduce the number of clusters assined to unique textures spaces in the final output by a comparison???????? far beyond my scope tbh. If the AO is separated to another UV like an environment light map it shouldn't be a problem. Good question. Houdini ganbareee!!

can you bake the ray directional vertex information to the card's Vertex Color. Its the information that realtime shader use to play wind animations. but its not on texture space but on mesh's vertex's color information.

Would it not be better to create a bone chain that runs along the clumps center skin then add physics to the bones?? That way you could have interactions with other bones. Wait... Can you dynamically move vertices in a differed rendering? I suppose you could just set a 0 at the root and 1 at the tip and just add a random noise to the scene for wind etc that could work. It works on grass right!

this is awesome... but holy shit that's a long ass process... we need a plugin to do all of this

Just curious, my low poly model has been topologised in quads, not triangles, will this still work?

Wow. That workflow is about a 1000x more complicated than it should be.

It got improved in Houdini 16.5 and 17.0

8k textures for game hair. Yeah, good luck with that.

some people generate their textures...

I think you can use this on characters for Cinematics and use a nearest match in houdini to grab a simpler texture that is close enough to get a close representation for real time use. cleanly creating the same quality with less texture space. This I feel is viable. I need to replicate this before I can be sure. would be nice to see the original Houdini Nodes before I put my foot where y mouth is.

It is certainly worth replication to see if it is viable or if it can be optimized. Which it with ought a shadow of a doubt can. Nice work! Been pissing about with xgen in maya and trying to get it to behave the same way and then I find this. Nice work!
