I've tried everything found online, and suggested in forums but can't seem to achieve the realism I need. I'm looking to etch a logo and text in a whisky bottle which will not only create translucent glass, but will lighten the area. The problem I have is adding the layer to the existing material and making it look convincing. I've tried different masks, layers, etc. with no success. Below is a photo of what I'm trying to create, and the my work. Any help would be greatly appreciated. This is the real bottle...
I think there are a few ways you can achieve this. One way is to create a suitable mask from your base image (The one with the double D logo") using an RGB to BW node and a ColorRamp, and use that as a mask between a normal (unaltered) Glass Shader and another Glass Shader that has had it's Normal, Roughnes, IOR (or any combination of the 3) "warped" by a Noise Texture:

$\begingroup$ Glad to hear it works - if you want to improve over my example, up the Noise detail to 16, increase the scale a bit and increase the mix with white on the MixRGB node to .98 or so (makes it more subtle/realistic). $\endgroup$ Nov 29, 2022 at 15:32
