Any chance you could share the settings you used to get to such a good image? The Luxus PDF documentation is a bit sparse, and video tutorials make me crazy. I hope they come out with some presets to use as starting points; that would be really helpful.
GLOSSY TRANSLUCENT WITH VOLUME:
Diffuse Color: Diffuse maps and desired color.
Transmision Color: Darker = less translucent. I used a dark gray here.
Specuar Color: Specular map and desired color.
Roughness U and V: How glossy the surface is. Lower = shinier. I used 0.2 here.
Absorption Color: Color of the light passing through the model. Dunno why, but you use the negative of the color you want. In this case I wanted orange, so I set it at 0 157 255 (intense light blue).
Absorption Scale: How much of the absorption color is seen. I used 4 here, but that depends on you and even the angle of the light I guess.
Volume Type: Homogeneous
I don’t remember the snake, but it was something similar with a darker diffuse color. I also used a Geometry Shell with Glass 2 with a Refraction of 1.2
Light source is a huge plane.
The real documentation for me are the documentation and examples of the LuxRender site. All the info is there already.
Well, I tried this, using the documentation from the Lux Render site (actual documentation! Imagine!) and the upside was that things came out MUCH better. The downside is that, considering how things worked out, you can imagine how very bad the first few attempts were. I used the Luxus SunSky settings, rather than a big plane, for light; I tried the plane, but I think there’s a core difference in how Reality and how Luxus pass light settings through to Lux Render that I’m just not understanding. I saw the light settings in Luxus for lights that I converted, and the gain was so low that I don’t understand how Lux is seeing any light at all, but somehow the character wound up being completely blown out.
I think there’s something about how the absorption colors work that I’m also not getting. Everything I tried wound up with him coming out some violent shade of purple or red, and eventually, I just turned it off. The result isn’t that far off where he’s supposed to be, but it’s a much more saturated and somewhat darker shade than it should be. I tried lightening his diffuse—he’s Ubersurfaced, so it’s not white, but I got it much closer to white than it is in 3Delight—but that only helped a little.
I think after some more work, eventually I’ll get it. Eventually. I hope.
Below, PD Sam from both Luxus/Lux Render and 3Delight; which one is which will be painfully obvious, I think. (Don’t ask me why he looks so demented in the 3Delight image. I didn’t do that!)
