Mix BSDF issue

Recommended Posts

Hi guys

I'm doing a BSDF mix in vops with a float attribute which is defined by an attribute transfer. but as you see in the image the mix between two shaders (sss and steel) is not correct despite the attribute is  0 or 1 for all points. can any one please explain to me the probable reason? is there an alternative way?

Thanks in advance

This is because SSS component is not within BSDF, but in the emission (Ce). You can see that your BSDFs did mix properly, but SSS is still added on top.

 

You have to subtract it by the same amount you mix. Multiply your Ce, or if you are using Surface Model (as I'm guessing) it might be convinient for you to plug your mask into SSS Intensity.

Hi teratera. That's right. its for emission and I used physical sss so I should subtract Ce.

Thank you
