Ah, sorry about that, I started work on another scene which also crashed, so the bugreport has most likely been overwritten, although the crash happened in almost exactly the same circumstances as the previous one :
- Different scene,
- Scene was stable previously,
- i started assigning BC3 compression to color textures through the Octane Texture Manager,
- Crash occured after doing so for about 50 textures

This is probably not ideal, if you want I can reproduce another crash and send you all information at once this time ?

Thanks again for your help.

Hey aoktar, I don't mean to press you, but have you had a chance have a look into it ? Do you have any news ?

Hey aoktar, just to keep you updated on what we ended up doing ; we converted all of our RGB textures to BC1 compression in .dds format outside of Octane. We are getting almost all of the VRAM savings that we had using compression inside Octane, but it is very stable and we have had no crashes.
