Making a set of 'space but not trek' walls and floors - for exteriors. Not metal, not wood, not plastic. I've done a matte ceramic (similar to the space shuttle ceramic tiles look).
The problem I'm having is colour matching between floors and walls.
Inside - no problem.
Outside in the shadows... not that much of a problem, although the floor tiles are darker than the wall, we can blame that on the way the light is hitting it.
Outside in the light however, we're getting quite a difference in colour from the matching values.
There's a significant tonal difference between the wall and floor - and it's not pretty.
I've checked the TXMT, and the co-efficients are the same for both wall and floor:
stdMatDiffCoef = 0.8,0.8,0.8,1
stdMatEmissiveCoef = 0,0,0
stdMatEnvCubeCoef = 0,0,0
The reflectivity is the same as well = 0.5
Differences - Floor as a Reflective Strength = 1.000000, that Walls don't have.
Walls have a huge number of fields that floors don't have.
Is this a known problem, and if so is there an easy fix for it? Or do I need to make the floors purposefully a different colour to mask it?
