The following OSL material emulates the skin shader made by Tony Reynolds which employs layered subsurface scattering modulated by red, green, and blue wavelengths**.** You can get the OSL code for the material here . I’d love to get feedback from folks trying this material out. Feel free to post yo…

I’m testing it, my first impressions are : ca you make it Directionnal, like in the Alsurface shader from anderslanglands Loading... so that we had less SSS blending like between the lips etc. ? From what I see, it’s a bit slow to render compare to the SSS2 but it’s rendering ^^ . So we don’t ha…

It has the same problem as the sss2 , way too much bounce bleeding sss if you want, let’s say between the lips.. we get a red line.. probably because the light is boucing too much inside the shader and then it creates a redish line between closes surface, like lips, eye eyelids fold, etc. wich is no…

Very interesting sss shader you did here, look’s a b it better then the sss2 in the SSS perspective, look’s a bit more accurate. It’s really slow though but look a bit better ,wich I like :smile: I hope you can make the diffuse slot work on 3dsmax so I can do further test :slight_smile:

The shader uses the vray_subsurface closure, and I don’t think there is a way to make that directional. Maybe Vlado can comment on that. From what I see, it’s a bit slow to render compare to the SSS2 but it’s rendering ^^ . It combines three sss2 materials, so it makes sense that it would be sl…

Here’s an image of the interface it shows in max [OSLTEST001.jpg]

Regarding mipmaps, if you are using 8-bit files mostly, you will want to use maketx . I have a tutorial for it here , but note that it is written for Maya.

[image] Download V-Ray Ho like in one of the Mr skin mtl they made ^^ but in my max interface I don’t see these control.. I join an image to show the interface I have in max. In the image I see a color swatch by the RGB_Scatter_Depth. Just change the color, and the red, green, and blue depth…

ok but in max, we don’t have acces to the RGB channels of a flat color. We need a slot ,like for the diffuse, so I can put a color there and modify it with the 3 channels .. would be better for max to have, like Mental ray did, a button called R: with a value associated to it that you can tweak, the…

Can’t you just click the color swatch and have the Color Selector open? The Color Selector in Max has an RGB section in it. In your pic the Diffuse Color and the RGB Scatter Depth both have color swatches so they should work the same.

Ha ok you mean just that.. I though I would need to use the output in map map where I can control with a curve editor the RGB independantly.
