A magical scifi Portal made with Blender. Both high and low poly possible, depending on the subdivison level in Blender. The Portal itself has only 533 vertices and 512 polygons/faces (lowest subdivision level) but can be a lot more if you crank the subdivision up .

Everything which you can see on the renders are included in the different 3d files (.blend/ .fbx/ .obj / and so on). It is perfect for any game project (from mobile to high end PC), since with the blend file you can choose on your own how subdivided you want the model to be, and export it for your favourite game engine. If you have trouble doing that, you can shoot me a message and I'll help you out.

The textures of the plants as well of the portal stones are made with PBR texturing, so it should be quite easy to open up the model in any other program and quickly assign the different textures (albedo, ambient occlusion, roughness, normal, displacement..).

The animation of the rotating vibrant green portal plane was made with blender shader nodes. If you want a similar animation of the portal plane in Unity3D I can provide a screenshot of that since I did this once with Unity shader graph already.

The plants have included PBR textures and are uv-unwrapped but do not have UV-lightmaps yet. But I guess it is very easy to auto generate them either in blender or in your favourite game engine.

The different pictures of the portal were rendered out with different HDRI light (standard Blender) environments, which are included in every Blender version and can always be used for free.

I have included a youtube link where you can see the portal in action (I used Unity as a game engine in this example video)

If you have any other questions you can always write me.
