thinwall glass material look bad on my glass models

Yes, thin walled glass still works bad for some meshes, but solid glass must work fine. Can you share this example of wineglass by attaching it here. Just isolate it in the blend file, no need to share all scene.

Seems like it’s works fine with solid glass. Does it the same model of wineglass? I think it was something wrong with the previous model.

Try to use SSR for this mateial this may help, but unfortunally for now to get something good for transperency in the engine unpossible. Thinglass good mostly for one sided planes or something (for windows for example), solid glass good for balls or glass figures. SSR can do some job but it will be very hard to render for moble devices and some old PCs.

Is there any info / docs about using this, how to setup and do I have do something in blender too?

YOu just need to have refraction on more than 0 or use refraction node, or use Solid Glass shader that already has refraction set 1. You can try to use Simple Refraction (it’s very simple to use) or SSR Refraction, but tweaking may take some time. It’s still a “dark matter” even for me can’t give you too musch recomendations and docs keep silince how to properly set up it.

You do not need to add anything for Solid Glass shader, just assign it and then go to puzzles. I mean if you do not use Solid Glass shader you need to add Refraction manually to your shader that you already have.

Try to change color of the Glass Shader node to white.
