Oh i missed the quad plane, but the box is implemented. Also want to add the ability to change the light direction later on, but i hope that suffices for now.
BTW: Doubleclicking on the Preview will reset the transform of the mesh
Thanks for your reply, i really appreciate your feedback!
At least i will note down this bug and check it out in the future. As you can see in the timeline, the developement slowed down over the months, since i am working on different projects, but from time to time i still work on it. Hit me up, if you have any problems.
Schöne Grüße aus Berlin :)
