I’m quite new to UE5 but not to 3D modelling and CAD.
I’ve been asked if I can make a factory in UE5 based on some cad models.
I thought, with datasmith, would be a breeze. But the solidworks models are way to detailed and contain every bolt and nut used irl.
The model loaded but I was greeted with the ‘video memory has been exhausted’ (I’m on a 1080ti, will upgrade soon).
So I thought I simply model the main big parts in Blender. So I set blender to real mm units and modeled a big tank. It’s just a cilinder with a dome and some simple details. Imported it to a new project, just to see how it turned out.
Saving-time is improved dramattically, but video memory is still exhausted.
I have a 1080 and my frame-rate isn’t super great when I am using the high settings in the engine. You are somewhat limited by your hardware in this case.
I can’t fully see your warning message. Are you sure it is not to do with textures? If you apply a single material to the entire mesh, does the lag reduce?
Haven’t applied any materials to the mesh yet, the colors are from the exported FBX.
Performance doesn’t get better when applying a single material.
I am using Nanite.
The mesh is using materials if it isn’t one solid color. So I assume there must be materials added to the mesh. If there are many material slots and materials are added, the mesh might be using many draw-calls. If you are using Nanite the mesh shouldn’t be so heavy, and it’s most likely a shader issue.
