Wardred,
Thank you so much for this response! I’m still a newbie with 3D, but I’m trying. I will look into baking my textures, as well as looking for lower texture resolutions although I’m pretty sure I’ve already paired everything down to 2k. I am not aware of linking objects in a scene, but it is something I will happily look into. As far as your questions go, here are my answers:
Video card: RTX 3080
OS: Windows 10
Number of verts in the scene: 2,343,480
Number of textures in the scene: Not really sure how to find this. See above where I claim “Newbie” status 🙂
