I have been experimenting with JPCT and everything was fine.
I had converted a GLB file into a 3ds file so that I can use it with JPCT, the model is correctly displayed with various online 3d viewers, but when I try that in JPCT when I rotate it, some parts of the object seem to be disappearing. I tried rescaling the model while loading and trying on another device, the issue is still present.
This is how I load the Object3d:
ModelAvailable(
Object3D.mergeAll(
Loader.load3DS(tools.getStream(model), scale)
)
);
This is the problem with only this model, other models are correct
