Error 700 - cant init devices

[Morne]

Hi guys

I was happily rendering along an a scene, until I couldn't. I deleted the last change I made when things was still working, but that didnt help. Restarted PC, didn't help. Switching between CUDA and RTX, doesnt help.
Isolating even just 1 object, and applying a default VRayMtl on it, doesnt help.

Its starts GPU engine, then within 2 or 3 seconds throws the dreaded 700 initdevices() failed error.

Any ideas?

(It renders fine on new blank scene)

......if I switch to GPU Bucket, instead of GPU Progressive, then it looks like it gets a bit further, but it never actually starts to render. As soon as the buckets appear, it stops again

Perhaps do a clean reinstall of your NVidia drivers?

Same issue here, so I went back to CPU. My scene was blown out, even after I deleted all lights, it was obviously a bug.

I think I missed the part where you said it worked with a new scene. SO likely not the drivers. Sorry.

I have had a couple 700 errors. One of them required me to restart the machine. I recall it involved using RTX.
