Maya 2020 fundamentals - modelling the real world
Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

refractive caustics with mia_material

hi, i am working a project that uses some nice thick glass and i need to use caustics bu i cant get them to render. I have a mia_material applied to my mesh and i have use caustics checked in both the material props and mental ray props. my light (a phys sky) has emit photons set on it. is there anything I'm missing?

I don't think the physical sky can do that, plus I think its a bad idea to use a directional light for emitting photons. I did a post on caustics . Hope that helps.
