Hello!

Any one who knows a technique for creating a video projection in Octane, or does it have to be faked in post? It would be nice to be able to create it in Octane in order to get the light distribution from the screen.

In blender you would create the projector and aim it at the screen. In Octane I suspect the solution would be to apply a texture and an emitter to the screen. With my present knowledge of nodes I have not been able to do this retaining a good quality for the "projected" image.

Cross my fingers some Octane guru will have an idea about this!

Thanks

I found the solution, and of course it was so obvious I´m sure that was the reason no body answered my post. If any one new to Octane would have the same question, here is the way I found to do it:

In a diffuse material, choose texture emission in the emission pull down menu. Load an image in to the "efficiency or texture" slot. Control the trade of between light emission and "image quality" with the slider.

Strangely enough I had a bit of different behavior in a daylight scene (tv) and a closed room. In the daylight scene I also had to add an image to the diffuse.

I hope I can come up with a more challenging question next time

How can one create a projected animation?

and everybody is in silence...
