Big Memory Problem

[Micha_cg]

Today I have build my interior scene with glossy ground materials. But shock, the rendertimes and the memory usage was extrem long. So, I disable glossy effects. But the memory increase extrem - approx. 500 ... 700 MB.

For example if the material preview is rendered than the RAM increase approx. 300 MB!!! I have used a plastic surface with diffuse map and reflection map, both approx. 2000x2000 px. Is it a problem for Vray? I have thought, bucket renderer dosn't need so much memory. The problem is independent from the GI. Without GI the same effect. Only if I disable maps per global switch, the RAM usage is normal.

I have attached a screenshot: plain win Xp -> open rhino -> open scene -> render per Vray -> loading maps -> stop.

Any suggestions? I hope it is only a bug or a mistake from me.

Also, one or two times I have stoped the rendering berfor the progress window was open (it need a very long time) and Rhino crashes down.

please send a scene with all the textures, etc, to me. I'll see if I can find what the issue is.

I have send it (approx.5MB). Good luck.

Ram usage of 500Mb doesn't seem that high to me?

Big Memory Problem

The top usage in the diagram is approx. 1.3 GB. I have done a new test. Reboot my system, open Rhino, open the scene and render - approx. 1GB RAM usage from Vray (with eight textures, some with approx. 2000x2000). I hope, it is a bug.

Yes I have noticed too that Vray takes a lot of memory when trying to do a high quality render (it might be my inexperience with the controls though)

Interesting for me: only if I global disable maps, I get a normal memory usage. If I disable GI, nothing changed. It seems to be, that the maps are the problem.

ok, I've looked at it. I agree that the memory should not be jumping as much as it is. I'll keep you posted on the progress on this, but I need to ask Vlado a couple questions before I can fix this problem. Thanks for bringing this to my attention.
