ok, here I am ... I renderes wdirectly (left) and with Render Knight (right) both settings were the same.

Even if it does not glitter .. I like the outcome and I think this is the solution for my latest problem :)

Do you have a suggestion how to make glitter for Superfly too? I tried a tutorial for blender but failed and landed accidantly on the material I posted now.

I am looking for a glitter like in this older item.. Firefly works fine, but Superfly will not render the particles. (this material was my starting point to modify before I landed on this material :D )
