<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">No, I don't. I need to preserve the original normals that ASSIMP imports because ASSIMP calculates the normals correctly. Otherwise, I can't identify the UV seams.

<div>I can just do this computation in the SurfaceMeshRenderDelegate, but I'm not sure if the normals are used elsewhere after reinitializing the meshes. But isn't reinitializing a mesh dangerous in a multithreaded environment anyway?<br>

<div> This is cleared in case one wants to reinitialize the mesh with a different data. Initialize should only be called at initilization or at runtime if the mesh data itself changes. </div>
