Color id map. 4 different roughness control

Hi guys :slight_smile:

Can some one point me out how correctly and separate control roughness over 4 color id map.
My color id map are RGBY (reg, green, blue, yellow). I use mask nodes and with lerps control colors of 4 different model parts. Everything works fine. But i cannot setup material for separate control roughness of 4 parts of the model.

Can I see your material editor?

Thanks for answering but nevermind, i found that setup with color id too complicated and just switch to multi material id on separate mesh polygons which are way too simplier and fast to use :slight_smile:
