Just bought Octane render and blender plug in. Great product. In blender i could hide an object from transmission ray and shadow ray. Is there a way to do this in Octane/blender plug in? I do not mean opaciiy. I want the object to be visible but not cast shadows. For an interior sceene i might place a plane outside the window with a background image and i do not want it to cast shadows.

This question might better be answered in the Blender sub-forum here.

Yeah i tried that. No replies. Can you hide objects from shadow ray while still being visible in final render in Octane stand alone? If not how do you usually add a background image outside a window for example?

If i want to use the daylight system and place an image texture outside a window i guess the only way would be to render with background as alpha channel and later add the image in potoshop?

If I do an animation I would have to animate the scene with only the background a second time and then overlay the 2 in premiere or AE? That is the only way that I have come up with. If anyone have an easier way please advise. In Blender I could just hide the plane with the texture to shadow and transmission ray. Just need to know what options I have.
