An eldritch or dark fantasy portal-gate model for transportation between realms. This is provided as a half-ring design, which could be used by itself or duplicated to create the full ring.

Zip includes model in .obj and .fbx as well as example 2k PBR textures for diffuse, roughness, normal, and emission. Textures were baked from a procedural material, included in the .blend download, using the paid SimpleBake Blender addon. The main preview image shows a simple example setup in Godot Engine using the provided assets.

Fair warning that the UV mapping on this is not the best as I lack expertise in that area - I had help from Blender's provided auto projection, so it's workable but probably suboptimal.
