I’ve been dealing with Blender scripting and apparently NOT dealing with Blender mesh modeling for a while so I fall in a situation that is really strange to me. In one file (only this file) I have some meshes that look as being one-sided. Pls look below and you will get the situation better - depending on the view point the object(s) are visible or partially of fully invisible… I dont know what setting shall I adjust to put them into "normal"state (two-sided visible). I think it is a local to this file setting cause I dont have that kind of a problem in other .blend file. Pls helppppp!
