Edit : I found the origin of the problem, my UV editing was not good !
Hi ! I have a little question about mapping : I made a quick cube in blender (I would cut a door inside, that’s why I didn’t did it in smode.), Each face is one object. I import as a group and assign each face to a content area.
I then create VP but here the problem : I don’t understand how works the mapper added automatically witch transforms my image (like a 3D transform). So the VP project an image unusable. I achieved my using a ‘full’ instead of that one, but still I want to understand how it works and why it gives such transformations? In that example, when I am in ‘preview‘ it seems that it’s that transformation which is used, but in simulation it works as I want... I took another captures but I can post only one capture
