VR for complex construction CAD models
Hello,
I work in construction and we are trying to visualize our projects using Unity and Oculus Rift.
Basically all our models are created using Revit and we export them out to fbx and bring them into Unity. For each model we have (electrical, mechanical, architectural, facade...) we generate a fbx in Revit and bring into Unity.
The models have around 3000 to 60000 objects(meshes) and around 3 million to 40 million polygons. When we try to visualize the models in Unity we are getting very low FPS, around 2 to 3 fps, and batch draw calls around 15000 to 20000.
I believe the problem is the complexity of all our models that we bring together into Unity. I wonder if there is any way to optimize it, I already tried decimating, disabling shadows, occlusion but nothing seems to work. Collapsing the models into a single object is not an option because we have to allow the user to select and inspect individual elements.
