Texture limitation/problem?

Just bought VrayRT and testing it and so far its quite impressive, but…i ran into a problem. The latest scene i am working on doesnt work with VRayRT. If i start a new scene everything is fine, opening old scene works too, but in my latest scene i get the following error in that DOS window:

Failed to create temporary file
Unhandled exception occured, will exit render loop
Unhandled exception occured, will exit render loop
Unhandled exception occured, will exit render loop
```This happens right after VrayRT loads the textures, in this case VRay sometimes loads no texture at all sometimes this comes after two textures. 
In the active shade window i get this error: 

Wating for image data…
error: Render host [name] (127.0.0.1) disconnected


thanks for any help in advance

This message is printed out by the JPEG library; not sure in what cases, but one user reported that “turning down the UAC control level” helped. In any case, if you can get me this problematic JPEG file to vlado@chaosgroup.com, it will be very helpful to resolve the issue.

Thanks for the quick answer, but i am using win64 and not vista where you got this uac control level - or do i have this in win64 too? The problem with identifying the texture is that sometimes it will load textures sometimes not, its kind of random so i dont know which one it is. I will start replacing textures and if i find the one causing the problem you will get the texture.
thanks again.

i also got the unable to create temporary file problem. i tracked it down to single jpg. but the strange thing is it worked ok at first…

i halved the map resolution and it works again,
then i put the orignal resolution map in its place and it still works! very strange problem…

I think I might have a fix for this; if you wish you can email me to vlado@chaosgroup.com for more info.

Best regards,
