Model changing when rotating #215

Closed JunchenLyu closed 3 weeks ago

JunchenLyu commented 3 weeks ago

Hello, I am now trying to do a simulation of rotation, when I successfully load the model, I found that when the model was rotating, some of the meshes had randomly connected together, making the calculation unreliable. Seeking for help! Thanks in advance. 屏幕截图 2024-08-18 143618

Hi @JunchenLyu,

this happens when the mesh is not watertight, meaning there is holes between triangles or triangles are overlaying. Try fixing the mesh or reducing triangle count a bit; Microsoft 3D Builder for example can do this.

Kind regards, Moritz
