Using RPC with V-ray the shadows doesn’t work. Why?

A reader ask to me why the RPC (Rich Photorealistic Content) doesn’t project shadows using V-ray.
Yes, it’s right. There’s some problem using both RPC and V-ray. When I had the same problem I must retouched the render with Adobe Photoshop. That was the only solution I found.
But not any RPC Archvision library has the same bug. There’s same collection that works fine, for example the Cars.
Anyway if you already completed your work and RPC doesn’t project shadows I suggest to “repair” it with a little postproduction (with Photoshop for example).
I think this is the best and fast way.
Besides if you want to get a more photorealistic renders I suggest to try different solutions like 3d low-poly people, for example Axyz-Design.
It allows a free download to try the models so… enjoy it!
