I'm fairly new to Blender and 3D modelling in general. I segmented 4 different structures from a CT scan, three lymph nodes and the the surrounding skin surface. I imported these models into Blender and applied some remeshing and smoothing.
After that, I'm exporting the models as .ply files and reading them inside my OpenGL program. I implemented my own PLY-parser which seems to work perfectly fine for the three lymph nodes, however the vertex order of the skin seems to be totally messed up.
I couldn't find any errors in my code and I'm pretty sure there is something wrong before exporting the skin model from Blender.
Any ideas what could be different for the skin model and the lymph nodes??
