Hello

I sometimes have projects where I have to do “previz” type renders with placement of video screens or lighting in a room.
I’d love to find a way to do this in Cinema rather than Unity or other real time tools where the rendering quality is inferior.  Are there any good workflow tutorials for this kind of thing?  I’m imagining baking all the lighting in the textures so C4d doesn’t have to recalculate it for every frame?

Thanks!

Hi Alex,

There is a [R21 menu] Object Manager> Tags> Material Tags> Bake Texture Tag. There are a lot of options. Crucial in such a set up is a good UV mesh, so no part of the texture overlaps. If the object doesn’t have one, an option is given in the Tag.

There are two main ways, Bake Material or Bake Object (Shift + C to get the Commander, then type in Bake Object)

An alternative would be to just render from a camera view and use this camera for camera projection to project the rendering back on the object with a new Material.

As a side note, when you bake a single light set up, you can bake another when the light settings change. The two resulting images/textures (or even more), can be then placed into a Layer shader, and animated:

Scroll down, I have illustrated that set up there. Here is a tiny little demo clip:

If you like me to have a look at a scene of yours, please let me know, I will send you an upload link.

Use OpenEXR, any Integer based format will clip anything above 1.0 (100%)

All the best

Thank you Sassi!
Sorry for my late response, but this is exactly what I needed.  And the light mixing approach is fantastic.

Thank you!

You’re very welcome, Alex, thanks for the reply.

If there is anything else, just let me know, I’m happy to look into it.

My best wishes for your project.
