I thought I had posted here yesterday, sorry if I did and this is double (can't find the original post now)...
I'm having difficulty with the mia sun/sky in a large scene containing buildings on concrete with grass around. I'm using the gamma correct nodes, so that's fine. My problems are:
- I'm using mia materials mostly, and they tend to take on the color of the sky. A white roof appears blue. Reflectivity is 0, and I've checked all the settings that make sense to check. Diffuse weight dulls them, but doesn't make them not blue. How do I turn down their absorbing of other colors?
- Around buildings there appears a faint rust colored falloff on the concrete ground. There is nothing in the scene with this color. Under mia material there is a similar color for translucency (under refraction) but I don't have this turned on, and changing this color doesn't seem to help.
- Finally, I'm using some layered textures. These feed into the gamma correct node, then a lambert. They work okay, but when I try to add a simple lambert on top (with or without its transparency node) the lambert is completely blown out. I have to make it black in order for it to be a barely passable color. Why isn't this part of the network corrected in the gamma node? Is it just lamberts that are bad? I'd prefer to use an mia material in the layered texture, but I can't do that without it bringing up the connection editor - at which point I get stumped again (default is curiously not an option here).
Sorry for the problem overload. I've used this setup before, but I'm getting more picky at attacking the problem spots. Thanks in advance for any suggestions...
