I used the material offset of Solidify to create this donut with glowing edges. base color material bloom material
I'm using two materials, one for the base color of the donut and the other to control the color of the bloom. However, if I create the emission material (the base color of the donut) first and then create the bloom material, the material offset does not get applied. If I delete and re-add the emission material in this case, I can use the material offset. But if I create the bloom material first and then the emission material, the material offset is applied.
Why does this happen?
Here is my file.
