Short description of error
strange 'blue' appears while using a noise texture as a factor to Mix-Shader in eevee. And my world is empty.
strange results.
files following.
Actually , I find it is a math problem that I made by myself.
Cause the range of color in blender is '-1,1',and the factor only has the range from 0 to 1.
so I added a '-1', then it works well .
..
but here is a suggestion, why not turn the factor range in to -1 to 1 as same as the color range? I think this may be more easier for most users, right?
Color values in Blender are usually in the range from 0 to 1 (and not -1, 1). However, you can go way beyond that if necessary. -1 to 1 does not make sense as a color range imo.
The factor range is 0 to 1 on purpose: https://wiki.blender.org/wiki/Source/Render/Cycles/NodeGuidelines
If the color range is from 0 to 1 , the same to the factor of Mix-Shader 0 to 1, why this happens? Then there must be some problem.
