ParticleSkull Posted May 25, 2017 Share Posted May 25, 2017 Hey guys, I don't have a lot of experience in SHOPs yet so I'd like to see if someone could give me some ideas for this. I'm developing a procedural eye and I'm able to do it's veins procedurally on SOPs but I guess it would be much more useful if I could achieve something in the shader, maybe using some kind of noise. I don't know.I'm kinda stucked in the beggining so I just need any kind of ideas here's a good reference (I like the thickness variation) Quote Link to comment Share on other sites More sharing options...
konstantin magnus Posted May 25, 2017 Share Posted May 25, 2017 You could overlay to noises, one for the veins structure and one for their thickness. veins.hipnc 1 Quote Link to comment Share on other sites More sharing options...
Atom Posted May 25, 2017 Share Posted May 25, 2017 (edited) The first thing that came to mind was an L-system 2D plant projected on to a sphere. Depends on if you need actual geometry. You can vary the thickness by routing the lsystem iteration value to the width of a polywire. ap_lsys_veins.hiplc Edited May 25, 2017 by Atom 1 Quote Link to comment Share on other sites More sharing options...

ParticleSkull Posted May 25, 2017 Author Share Posted May 25, 2017 Awesome, Thx!Konstantin, thank you man. I don't have Houdini in front of me but I can't wait to check it outAtom, thx but like Konstantin pointed, I could do it using that setup from Ben Watts / Entagma to connect points, it works really awesomely but it's really expensive both to animation / simulation and render time.

ParticleSkull Posted May 25, 2017 Author Share Posted May 25, 2017 Alright, i'm on Houdini now @konstantin magnus, it looks awesome, very promising! You did it in vops. Do you think it's possible to use the same setup in a shop context? Because my eye's mesh is not very dense. I'll try the idea in shops right now but, as I said, i have huge lack knowledge in shops so I'm not sure if I can make it. Quote Link to comment Share on other sites More sharing options...

For transferring this to /mat or /shop context you just have to replace pos by UV coords or relbbox, adjust the frequency and apply a PBR shader (see attachment). veins_mat.hipnc 2 Quote Link to comment Share on other sites More sharing options...
