Specular Color 255;255;255 doesn't work initially #4

Open lucasw opened 6 years ago

lucasw commented 6 years ago

When the specular color of a light is set to 255, 255, 255 the specular light doesn't work unless it is first changed and then can be restored to that value.

254,254,254 works fine, and a small sample of other values.

This is using a dae file exported from Blender, I don't think other Marker objects have much/any specular.

I remeshed the cube in blender to get a cheap not-quite-per-pixel effect. cube.zip
