V1 of my glass improvement LoHA.
Depending on the prompt, and other LoRAs used, I find 0.8 strength to be what I use the most, but 0.7 to 1.0 should do it for your use case. Oh, prompt with glass in mind as this doesn't add glass to a scene (most times) though it will improve the glass that you prompted to be in the scene.
