Background image slow

[BorisGoreta]

I have found out that putting the background image slows down interaction of the scene considerably, like 10 times or more. If I instead put a polygon in the scene which covers entire background, put the same image on it as texture with front projecting mapping there is no slowdown at all.

Yes Boris, I know this issue. Problem is that Octane API doesn't support image background at all as far I know. Plugins needs to mix the background themselves using a custom functions (in CPU) and this functions are a bit slow for real time performance.

Anyway I will try to make this function faster for the next release.

That's what I thought, thanks for your hard work. This feature needs to be implemented by the renderer eventually.
