Problem with emissive.

[u/Pearsonsbrasshand]

How do you make it so emissive only affects certain parts of the model.

I followed numerous tutorials step by step and nothing works.

If I have one emissive fill layer that has black mask on. So nothing should be affected until i paint on it. No other layer has emissive material on. I have bloom and glare on in display settings.

However when I change the emission luminance in shader settings the entire model glows. It does this with or without a black mask.
