Projection Man / Camera Mapping in Octane

[bepeg4d]

Hi,
the power depends from the values stored in the image, so difficult to say, but since you can change the power slider interactively, it should not be a great deal to find the correct value.
Aboute temperature, please, use the Texture Emission node, in this way the temperature is bypassed.
The Kelvin temperature is related to Blackbody emission node, and used to mimic the different light sources.
About shadow catcher, you need to enable the Shadow catcher/Matte option active in the Common tab of a Diffuse material, or use the Render Layer technique:

Hi guys, @aoktar pointed to a sollution I thought it didn'r work but it does only that sometimes the geometry needs a regular subdivision. After some tries I realized camera mapping does indeed work.

cheers

It's been awhile but you can convert a projection into a regular material in C4D. Vaguely recall pining the projection to the UV.
