Lastly, the colour map. Not a lot to say. Extremes of light and dark should be avoided. Lighting detail should be avoided, so it’s worth noting that the shader in SP makes use of AO (ambient occlusion), and that this can be baked into the exported maps - it may be advisable to disable the AO in SP before exporting maps.
However.
There is a way of adding AO and other maps for micro-occlusion in a controllable way with Cycles nodes, which could help bring out more detail and sharpness in a colour map. The Mix node in the Colour section of the Cycles nodes will allow mixing two colour inputs (the amount of mixing controlled by the Fac parameter) with blend types that anyone who has used layer blend modes in an image editor will recognise – like darken, screen, soft light, multiply, add etc. In the screen below I’ve added an AO map and am blending that with the colour map using overlay. Using a curvature map would probably be more appropriate for overlay; AO should really be blended with multiply.
Just another tool that is nice to have inside Poser to allow more control over a material - the Mix node has a lot of potential.
