Create Emissive Materials using Physical

Recommended Posts

Hey C4D family,

 

I have a question. Is there a way to mimic creating emissive materials (like in Octane) using the Physical Render? 

I know you can texture with luminance and bump up its strength, but it just isn't the same - or maybe I'm not doing something right. Is that the only way?

 

Happy rendering!

Welcome to the cafe ! :)

 

You would need to be using GI for the luminant materials way you mentioned to work, so just checking that, but yes that is the closest we get to TPR emissives in Physical. We can do it, but most would concur we can't quite get the character (particularly in relation to bloom fx) of the TPR engines. ProRender can get closer, as that uses a true PBR workflow, but that is not as fully operational in R19 as it is in later versions.

  • Spot on, Cerbera. Yes, I've been using GI. Just a quick tip that I've come across (don't know if its too obvious already), you would need to amp up the luminance brightness strength relative to the size of geometry to produce more accurate results.
