Material "limit" to quantity

[sandisnovikovs]

Hi guys,

 

I will try to explain as efficiently as possible.

 

I would like to know if anyone has come across this issue.

 

I have a complex interior scene with many furniture items etc. I have my GI set up. Using Iradiance + Light cache. Normally when setting up GI I tend to have material override and use standard vray material. Renders quickly and efficiently. When setting up materials with interior scenes I find easier to apply simple grey material to all objects in the scene and resolve the floor, walls, ceilings, one by one until I get the final look. I find that using material override, and applying Multisub material on glass or particular furniture as I work on materials and textures in the scene are not efficient enough.

 

The problem I have, is let's say I have 40 items in the scene. 10 of these items have wood finishes, glossy white materials, gold finishes etc. ( resolved items). 30 remaining of the items are still to be resolved. I will apply a vray standard grey material to all remaining unresolved 30 objects in the scene. When I render the objects that have the vray simple grey material applied to - return black in render!

 

I don't understand why? What I find strange is, if I apply the grey material to one of the 30 objects it will render fine! If I use the same material in "material override" slot t will render fine - all scene will be grey. It feels as if there is a "limitation" to how many items in the scene can have one material applied

 

I kept adding and adding one by one, untill I got to lets say 14 items with the grey material applied. Then I applied to 15th item, and boom, the grey material becomes dark (but not black yet!). I apply the material to 16th, 17th 18th item - gradually render returns darker grey until finally I have reached the "limit" and it returns black to items with grey material!

 

I don't know if I have explained the process and problem well enough for you guys to understand. I hope I did. I really look forward to your replies and see if anyone has come across the same issue.

 

Vray 3.0.7,

 

In scene - vray sun, vray sky, sky portals in windows.

 

windows 7 64 bit with 32GB RAM.

 

Any ideas, please, I find this very strange.

 

All the best!
