So I have a project i'll be starting later this week and its an animation of a building getting built.
One issue with this is that having done some tests, when rendering an object which has its translucency animated, the render times shoot up, and having the one computer to do this i need to keep render times down.
Is one viable option to do this in the likes of after effects, where lets say you wanted the windows to magically appear in the openings, rather than play with translucency of the objects, you would have a frame with them missing, a frame with them visible, and use the likes of after effects or premier pro to bascially blend from one frame to the other?
If not, any other ways of doing this?

If you have objects appearing gradually during fixed shot, doing a blend in post will definitely be faster.

You could do a pass with just the windows in their normal state, then blend it onto the rest of your footage and animate the opacity in AE. You could get creative here with masks and how the windows are revealed. What will your camera be doing? What will the lighting be like?

Lighting will be pretty basic, im thinking just a VraySun, and the camera I havent quite decided on but I imagine it will simply rotate around the building as its getting built.
I imagine the blend will be a bit more difficult if the camera is rotating as opposed to static, so I'll need to have a look into exactly how I could do that.
Cheers guys.

Have you tried animating the opacity of the material on the object, rather than animating the visibility of the actual object? I remember having problems animating the opacity of the object but everything was OK when I animated the opacity of the material, and I seem to remember it didn't take as long.

No but i'll give it a bash and see what the difference is.
Cheers

It was a while ago that I rendered the animated opacity in Vray. Let us know if it affects the rendertime at all.

Will do.
Started this today after getting all the info I needed so i'll test it soon enough.

I did something similar this weekend.
I initially rendered out a turntable of a model rotating, and blending from base white, to gradient face map (to show wires), fading into diffuse and then diffuse with normal...
Took a lot of tweaking and hassle in the material editor. Then on the final model I realised I could just alter the composition or layer opacities in After Effects... So I just rendered out separate 720 spins with each separate material.
If nothing else, I got a bit of hindsight... :)

Well thats kinda what I was thinking, though rather than render the whole thing several times, just have a bit of a buffer in each version, enough to blend into and from, though the issue would be lining them up exactly in premier pro i'd assume if you do it my way.
Your way at least you have some reference as they all have the same frames.
