ISUther Posted October 21, 2018 Share Posted October 21, 2018 Hello, Is it possible to build VFX effect from textures in Houdini? Here is model what i have at the moment. If you look at original concept character has also those blue disease look a like veins under her skin. I can sculpt in those veins (or use mari texturing and from that get mask that i can then extrude and have those under skin and build VFX on top of it) Quote Link to comment Share on other sites More sharing options...
CinnamonMetal Posted October 21, 2018 Share Posted October 21, 2018 You could probably do this in most render engines, although if you are using Mantra, I think you may need a noise texture to be below an SSS shader so it can be seen. I would first attempt to paint this whether in a 2D or 3D painting program (Ps, Mari etc) to understand how the purple veins would move and end under the skin. By the way, she looks sorta like Medusa. Quote Link to comment Share on other sites More sharing options...
ISUther Posted October 21, 2018 Author Share Posted October 21, 2018 I also started to wonder should i make veins as separate OBJ files or polygoups? Can i assign effect on polygroup and not on full model? Idea regarding effect is this: Kerrigan face has clear skin and then the disease creeps in like under skin effect Quote Link to comment Share on other sites More sharing options...
ISUther Posted October 21, 2018 Author Share Posted October 21, 2018 Something like this: But more detailed. Note! I did not make the animation one guy helped me out a bit in forum Quote Link to comment Share on other sites More sharing options...
CinnamonMetal Posted October 21, 2018 Share Posted October 21, 2018 (edited) You could paint on the mesh where you want the veins then displace the painted attribute, and to animate as show in the video; you could either animate it by means of a dummy object or animate the veins by means of a SOP solver; read that data into a SHOP or MAT shader for the subdermal of the skin of a SSS shader. Or you could do it all in ZBrush and export the vein areas and import that into Houdini by means of a texture map.
