alsurface sss radius unit

[jasonhuang1115]

Hi,

I would like to learn if the sss radius in VRayAlSurface is in a specific unit or based on Maya's unit setting. For example, if I set the unit to "cm" as the unit in Maya, does that mean the sss radius is in "cm"?

Also, is the sss weight normalized among three sss layers? If all three sss layer weight is set to 1.0, does that mean each contributes to 33.33% of the total weight?

Hope to see some update to the VRay Next doc page for VRayAlSurface with a bit more examples of sss color and radius of the three layers interacting with each other.

Thanks!

The radius units depend on Maya's units, rather than having a specific unit themselves. And yes, the sss weight controls the effectiveness of the layer in relation to the other layers.

Thanks for the confirmation.
