OctaneRender™ 3.0 for LightWave™ - Production build 3.03.3

[Lewis]

Hmm ... "Update scene in GPUs" should be multi-thread. At some point Octane builds the acceleration structures, and this part is multi-threaded AFAIK.

I started IPR at least 50 times today and i have task manager open all the time, my CPU usage was 1-2%.

I think that the multi-threaded scene compilation is used only with big objects, but I don't remember the details.

Today i've got this error (log) few times (3-4) while IPR is on, computer locks out for a few seconds (just LW not whole computer) and then IPR goes to black and error message displayed so it requires LW restart to start rendering again.

GPUs are brand new and working fine, no overheating no throttling (temps from 55-72)

Any Idea what that might be ?

VRAM usage is pretty low about 2GB and i have 5+GB more free

Today is device 2 ??

Arghh .

Is there maybe problem with this build or some nvidia drivers incompatibility ? I'm using 372.54 WHQL drivers.

I'm getting wonky navigation with the latest Octane version 3.03.3. When I go to zoom in and out in perspective mode while holding the ctrl and alt key down it works but one I go to click and zoom in further it jumps back to it's original zoomed state and then sometimes jumps and goes all over the place. In previous versions it works great allowing me to keep zooming in on the model.

This problem has been fixed for the next build.

Thanks for reporting,
