I'm trying to make a transition from vertical to horizontal faces, but I have no idea how to do it without causing shading issues. I've never seen the pattern like this before and I didn't find anything simular on the Internet. My knowledge of blender are too bad to deal with it by myself. Here is an example of how it should look like if it is done correctly: I've been trying to fix it for three days, but I haven't seen any progress. Can someone take a look at it.
