vray displacement and multi sub objects
show user profile  Boing
I have a house modelled, all one object but different materials, slate, brick and smooth render. I wanted to add some displacement to the roof tiles and brick but can't figure how to do it with a vray displace mod as it'll only add one texture to the whole building.

I've tried putting seperate displacement onto each material but it leaves cracks at the corners, not as nice as the vray displace.

i could just break up the mesh into it's parts but if there's a way of doing it without that i'd prefer it.

Any ideas?

To whatever I know you can't work with vraydisplacement in such a case.

With proper uvwmapping / unwrapping, the corner issue should get solved.

i've never really learned mapping beyond the basics, architectural stuff doesn't need it. If that's the case it may be easier to just split the mesh up.

tick 'use object material' in the vraydisplacement modifier. then it will only displace if theres a mat in the displacement slot.

Put all the pollies in the same smoothing group to get rid of the cracks. That way you can do it in the shader without problem.

Indeed it's a pain in the ass with a single object. Split to pieces, apply uvw map and it will be quickest.

cadmonkey, tried that, didn't get much of a response unfortunately. It doesn't seem to be responding to the diffuse material and if i put a map in the displ slot it simply uses that and not the vray displace.

Undersky, that actually worked quite well but the max displacement is horrible compared to the vray one, very rough so i think i'll just have to split it up and use vray displace. handy to know though.

del3d, going to have to go that way i reckon.
