I've just replaced using Pandasoft X exporter by KW X-port, which for sure works better for complex scenes (in my case).
What I don't understand is that when I export a material with specular level = 0, it Always export RGB 0.9 / 0.9 / 0.9 as specular color.
For now I've fixed this by setting materials without specular reflection to 1 (scale 1 - 100) and only send float arrays to the shader if the R, G or B is higher then 0,01.
Does someone know how to solve this?
Any help appreciated.
