We've got a pretty big scene here and since we had a lot of problems with them recently, we decided to buy 1080Ti's to use a lot of vram they've got.
We had a setup of 2 workstations with 4x 980Ti's each on Win10. Our scene grew and grew, and it started this weird behaviour of replacing materials on some objects in PV - in LV everything was ok. We started exceeding the available VRAM, so we installed Win7 to utilise the rest of it. We started optimizing it crazy - making proxies out of everything and minimizing the number of materials, but nothing helped. The problems persisted and we had more and more trouble with crashing and - what we thought - too big of a scene.
Of course we tried it on 2 machines, couple versions of octane and plugin and 2 versions of drivers.
Now that we have couple of 1080Ti's and upcoming deadline, we had the same problem. So we went back a couple scene versions to the latest one that didn't have any errors, and started adding meshes and materials one by one. Now we have the same errors, can't find what causes them and it's quite possible we invested in 1080Ti's for nothing :/
Attaching 2 renders (4K, VR) and log of one of those. Can't attach scene because it's 600MB of super secret client-secrecy stuff.
If anyone knows what's going on - please share - we're wasting a lot of time to repair what we have and we still have to animate a lot :/
