This is a Pyramid with a Squared Spike with Entrance, ideal as a decoration for outdoors ancient or modern and why not futuristic scenes. It is handly to use when it comes to get some temples in your scenes for example or what ever you want to have in your decoration that you want to get this pyramidal sructure. It was made with Blender and rendered with Workbench, I also proposed other formats than .blend as : .abc, .dae, .usdc, .fbx, .glb, .obj, .ply, .stl and .x3d.
It is my Pyramid with Squared Spike which has no entrance (2.9$ model : https://www.cgtrader.com/3d-models/architectural/other/pyramid-with-squared-spike) to which I added an entrance and a triangular shaped inside to it.
This is a model wich has no textures or material applied to it, you would customize it yourself. The advantage is that, in case you want to apply your own textures and materials, buying this one is cheaper than buying a version of it wich has textures or materials applied to it.
It is 234 polygons and 298 vertices.
I am at your disposal if you have any question.
Enjoy, thanks !
