i don’t. i mean literally that’s all there is to it… make a bunch of crumped up planes, texture them with a transparent cracked texture (literally just photograph some ice cracks and use it like a mask), wedge the planes inside your ice object, then turn off primary visibility. enable glossy refractions on your ice material and you’re good to go

it wasn’t fast but it was simpler than a volumetric shader, especially in vray 6 years ago

Some funky stuff in there.

Needs this too: “`python def isHDA(node): try: node.type().definition().libraryFilePath() return True except: return False “`

i finally figured out how to create Cryptomatte layers from geo attributes so you can make per-piece or per-prim mattes without having to manually create ID attribs and bind export them… but it seems a bit of a silly workaround and i got super lost with the whole properties system. if any real mantra heads fancy taking a look: http://lewisinthelandofmachines.tumblr.com/post/176559578118/houdini-per-piece-cryptomatte-mantra-support-for
