Hi all - I've tried to search for this with no luck so apologies if I've missed the solution somewhere else.
I'm rendering a simple animation in vRay (no GI) with a building fading in from 0% visible to 100%. See attached (chapel_01.jpg) for how it looks mid animation. What I really need though is slightly tricky to explain. I need to not see the hidden geometry when it's fading in. I'm just changing the object's visibility in object properties at keyframes so at the moment it's 'ghosting' in whereas I need to not be able to see geometry behind. I've mocked up what I need in photoshop (chapel_02.jpg) and if the camera was static then I'd just compile in post but the camera has movement so I can't. Any ideas?
Any help very gratefully received. Thanks. Jonty.
