Oh,I forgot to add this question.

Have you guys had any problems with your memory?

Since I got SKU 7 and Vray 1.48.66 , it seems to me that more memory is used.

And the problem with me is that whenever I render, Memory goes up to 1.8 GB (in task manager - PF usage) and never comes back.  
So if I tried to do 2nd rendering it actually doesn’t even start to render.

I have to close sku and re open to render 2nd shot.

Any suggestion on this ???

Re: Memory increasing problem

we have received this report from others as well. Upon testing in windows xp professional, I noticed an odd behavior. If you are rendering, and you completely minimize sketchup and the vfb… the memory usage drops to a considerably lower amount. Then when you restore the windows, the memory usage remains at that lower level for a moment, and slowly climbs… very odd. This is with the current beta though, not 1.48.66. I have not tried to reproduce this issue in that version. We are still trying to track down the issue.

Re: Memory increasing problem

I had the same issue when I switched to Vista 64bits.  
The RAM limit was hit at every renders..

Now I tweaked SU (with a small software ) to use up to 4gb.

I don’t have any problems with memory limit now.
