glow/bloom alpha issues
Hello, I am trying to use self-illuminated shader together with the glow-image post-effect, to make parts of an object glow. But the whole object is glowing, not only the parts deffined in the emmision-map (because of the specular map).
my setup: Into the self-illuminated bumped specular shader me inputs: 1.slot: diffuse texture with specular in alpha channel 2.slot: emmision-map (with generate alpha from greyscale, without it dont works) 3.slot: normal map
The problem occures when using the glow image effect (or bloom and lensflare), the specular alpha acts as mask for the glow/bloom NOT the emmision-map. I also see my specular map shown in the scene viewer when i switch to alpha-view mode not the emmision-alpha. How can i have only the parts glow/bloom that are defined in the emmision-map? What am i doing wrong?
Im totaly stuck here plz help!

edited the shader and fix this with writing the illumination map into the alpha channel, now it works like a charm!
