Way to finish strong @interuse! You really brought this window home in a beautiful way. Looks great in the assembly:

I made some small to the tweaks to the material and also optimized your textured down to 1024 as well as combined your metalness, cavity, and roughness into one texture image. Since they’re all grayscale I made the Cavity the RED channel, the metalness the GREEN channel and the roughness the BLUE channel. I went over this process in the week 4 casual stream if you want more info about it. The benefit being we only load one texture file for all 3 textures.
Excellent work this month! Thank you for joining and contributing to Collab2021. It was a pleasure working with you 🤝
