The model has been created in Blender 3.1 and rendered in Cycles. All textures of the model are PBR textures. Because of its high detail (all details have been modeled, they are not textures), it is a high poly model and can be converted to a low poly model. The model has been created for a Star Wars scene study of mine and the scene will contain, Imperial At-At Walker, R2-D2 and X-Wing from Star Wars.
The blender file does not contain the Death Star model, but in case of request, I can supply it free of charge (It is not fully modeled and low poly Death Star, for that reason, I removed it from the Blend file)
All other formats have been exported from Blender 3.1, therefore, in case of any problem in any file format, please feel free to contact me.
