Ah yes, you're right, there are various diffuse lighting passes but not a shadows-only pass. And I don't think the shadow catcher registers in the render passes on the moment. If you can tell me more about what you're trying to do I may be able to give better advice.
If the diffuse is calculated as a phong or lambertisn term (like it probably is) then diffuse power should have the same effect on model lighting as spec power does on specular lighting. Ie make it More directional and less diffused. Just slap a constant medium grey into the diffuse slot, then put a scalar into the diff…
Something I forgot was that if you have a texture slotted in diffuse in Maya, it also sets the diffuse channel to black (which gets written to the mtl file). I don't know Vue, but some other programs I've used have two slots for diffuse: a texture slot and a diffuse tint slot. So it could just be that?
If you have vertex color on your highpoly model, and you want to bake it to a diffuse map, you can make a material for the HP with a Vertex Color Map in the diffuse channel, and this will then bake into your Diffuse element in RTT.
Hey to all, I was wondering if anyone had a good naming convention or terminology system I could use to name the ARGB channels in my Gloss map (and use them as Masks if desired) for artist friendly reasons. To give an example of what I mean: +Diffuse+ =Enable Diffuse Roughness (Oren-Nayar)? (User defines if they will use…
Hi all, please can anyone advice me how to transfer color of diffuse map to vertex colors? Tryed this: http://www.polycount.com/forum/showthread.php?t=70981&highlight=diffuse+vertex+color not working for me. Is there any script for this? I must use old tech... :) Thank you.
You baked the Color(Diffuse) but you also need the Transparency(Alpha)? Select the Alpha map option but rename output file to the same name as the Diffuse map. Doing so puts the alpha into its own channel in the diffuse.
Hi guys, just starting my diffuse map and had a quick theory regarding the following: First Head: Vertex Colours. Second: Smooth Shade. Third: Normal map and diffuse. Now my issue is that whilst the diffuse looks like its coming on nicely in the first image, it doesnt look very good once the shading modifier or normal map…
