thanks for reply in ahead
and sory about poor english
All MatCap materials use a light map that’s part of the material itself. As such, they don’t respond to changes in the Light palette. If you want to adjust the lighting using the Light palette you need to use one of the many non-MatCap materials.
i understand…and thanks for reply
