Hello Octane support, Any opinions about this?

Another thing I have noticed, when rendering in the viewport, It updates the shaders in about 5 seconds, and uses all 8 cores of the CPU, when I hit render, It only uses 1 core.

Same problem here. During final rendering synchronizing objects takes 4-5 seconds while in viewport render there is no delay.
Any one can help?

Hi J.C,
sorry your question is not clear to me
I'm guessing, but if you are talking about vr output, you have to consider that the final rendering has a huge frame buffer compared to the preview window, and needs more time to be loaded.

Hi bepeg4d,
I'm not talking about VR output but long time of snchronization of objects during rendering animations.

Anyway I have solved it! This info should sticky You need to apply modifiers before final rendering. Lets take a Subdivision Surface modifier for example. It is applied every time before rendering next frame so it was taking some time for blender/octane to apply this to a mesh. The more sub divs the more time it took to synchronize.

In viewport it was applied so that's why it was faster comparing to the final render.
