Hello dear Blenderartist,
I’m trying to create a material for window glass with these characteristics:
- light emitting
- slightly reflective
- no shadow
I’m trying to do that with the help of the Light Path node, but I’m not skilled enough for the task, here’s my setup:
Something is wrong with it: looks like the direct emission light is not taken into account, and sometimes (yes sometimes) the window is not transparent, but that seems related to a cycles bug, since switching from GPU to CPU render and back often fixes the problem.
Anybody can please help with the node setup?
Thank you in advance!
Simple… 1 object, 2 quads, 2 materials:
a) inside invisible emitter or portal outside
b) transparent + gloss, no ior
- if needed for realism or if window takes a large image area, i also add some bump & another reflective surface with some dirt - of course it depends on the window/ glass type and installation
hello burnin, i would prefer resolving everything with just 1 object: i have my students striving to learn Blender and i want to keep complexity to a minimum
thanks for you suggestion anyway!
Ok, maybe it’s not the easiest possible setup, but with this i obtain what i was looking for:
- not blocking external lights
- emission for faking external ambient
