I have small problem, let say I have this mesh:
At the end it needs to be split into separate chunks/objects (in this example it's split in five chunks) like this:
The problem is that normals are wrong as opposed to original mesh which makes shading go wrong (visible seams between objects). I've tried to use Auto Smooth and it's quite better, but still worse than original mesh.
This mesh is just an example of my original mesh which at the end will be exported in order to be used in external game engine with OpenGL as a backend renderer, so for OpenGL it doesn't matter whether it's rendered as one object or not (I'm NOT using triangle strips) as long as normals are the same as were before. Is there a possibility to separate mesh into objects while maintaining original normals?
Thank you in advance.
