Emissive lightning on texture

Hello! I have a problem! I have a model with blue emissive parts and black body. But if I turn emissive black part lights by blue parts and looks as dark blue instead of black. Help me please!

Well you can’t emit black light. Either it’s emissive or not, black means it’s not, so you should probably change the color in the original texture to black instead of blue. You can still have blue emissive by using a mask and lerping to a blue color, then multiply by some number to increase the intensity.
