I made an edit to a mesh in blender then to .OBJ then to xsi then to .MSH. I can see the mesh in mesh viewer just fine, but in game, the mesh is invisible. I am using this msh with custom sides. Before, I accidentally put the OBJ in the msh folder and munged it and it was invisible, but then I deleted the OBJ, put in the MSH, and ran clean.bat in my side's munge folder. I then munged. It was still invisible. I have tried renaming the mesh and manually deleting files in my side's munge folder. Here are my mesh's munge logs: (Original mesh: tfo_weap_inf_e11new. New mesh: tfo_weap_inf_eee)
Model Munge Log:
What does the odf file look like? That's usually where problems like this occur. If mesh viewer doesn't crash then the model itself is probably ok, and your logs look totally normal (to stop the errors in the first log you can just add a tfo_weap_inf_e11_new.msh.option containing the line "-nocollision").
