I’m currently working on a car configurator and am having issues with Nanite.
I am using the same import and nanite settings for all of my meshes, however, the Interior and Exterior geometry stays black in the Nanite Triangle view, and the other debug options show the same problem - seemingly nanite isnt enabled for those two meshes.
I have imported the geometry via datasmith using Data-Prep recipes, merging the complex scenes into a single mesh. The Wheel and Seat geometry works fine, but the rest isnt working.
I found a different post stating that this is caused by Runtime Virtual Textures, 2-Sided Geometry or pixel-depth offset being used, but none of my shaders are using either of these features. I even disabled Virtual Texture support in the project settings. Does anyone know what else could be the cause for this problem?
(Please excuse the blured image, I cant show the car itself)
I would simply ignore this, as for the car configurator, the performance is still okay-ish. The car consits of 45mio polygons and the environment desert geo I created has around 5 mio.
The issue I am currently having, is that this level takes 37secs to load when the project is packaged. That is obviously waay to long (I tested using an empty level on startup, and that loads within 2secs after executing the .exe file).
