Vray Next GPU loading bitmaps error

[seandunderdale]

Hey guys.

Im RT rendering in GPU CUDA mode. Every 30 seconds or so, the bottom bar refreshes in the framebuffer, saying loading bitmaps, and all my texture connections drop out and the scene goes black. If I make a new texture or do something to make it refresh again, it pops back and everything turns back on. This happens over and over again and it very annoying. Has anyone else had this?

It seems like its more of a lighting dissapears as some textures in light materials are visible still. But all lighting info dissapeara and the shot goes black. No exposure changes in camera have any affect.

using Maya 2018.6 and latest Vray release (non nightly) Rendering on a GTX 1080Ti in CUDA mode. (no cpu involved)

What's the exact V-Ray version? What OS is this? What's the driver version?
Does this happen with every scene or just one scene?
Do you render with the 1080 only or do you use the CPU too?
Can you get us some logs? The Maya Output Window might have enough clues for us.
Can you get us a scene?

Vray Next 2.1 (v4.30.01) Windows 10. Ive been using GPU CUDA and Hybrid, the issues happened with both. Nvidia Studio Drivers 26.21.14.3086. I'll try to recreate it in a test scene. Ive been prepping up an unreleased car so I cant send any of that. It doesnt happen all the time, and I tweaked the IPR settings and it seems to have reduced in frequency. Ill keep an eye out for any details in the Maya output window. Sorry I cant be more helpful right now, as Im neck deep in lighting shots, and have just had to deal with the issue (by making and deleting lots of 3d textures). Hopefully next week when things have calmed down I can look into it more.

Give us a shout when you have the time to look into this again, it will be most helpful.
