Camera Mapping - Picture Compositing

[Rickmc]

Hi Forum,

I need some help from you guys.
I´m trying to put up a lighting scene in a 2D Picture.
My client (a Light Designer) wish some pictures from real scenes like a dinning room were I have to put in he's Lamps and simulate cone of lights on the Table.
So here is my problem, I can't get a convincing result.

I build a dummy table to receive the lights, its just a simple plane with a Frontal Mapping.

In Cinema 4d we got the “Compositing Background“ option in the Compositing Tag (see attachment 01)
Here my results (just an example), sure I'm doing something wrong : (

Attachment 02: Here I used only the Diffuse Channel.
As expected not what I need, the texture is not congruent.

Attachment 03: Here I used only the the Self Illumination Channel.
Also as expected the wrong result, self illumination can't receive Light and the Texture is darker then the original.

Can you tell me the right workaround similar to C4D´s “Compositing Background“?

Hello Rickmc

Could you please explain again what is the issue with Attachment 02. Your workflow is correct and it seems like it works as expected. Do you have a problem with the texture, or the lighting, or the projection? Please, let us know so we can assist.

Also, let us know your Cinema 4D and V-Ray for Cinema 4D builds that you are using.

Hi Viktor,

sorry for the excitement.
My problem was that I overlaid the “dummy table“ layer from Vray wrong in Affinity Photo so my result was wrong and unrealistic.
I fixed now : )

Please delete this post, it's Awkward

It's okay, Rickmc

I am glad you managed to fix your situation.

Enjoy your time with V-Ray!
