Hello everybody. I think I got myself into a trap. In our configurator, you start planning in 2D space. Where X is from left to right and Y from top to bottom. Then you can switch and see the 3D view of your planning. Now as I have forgotten or just suppressed it, is that babylon handles some directions differently. Now X is mirrored. I tried to but an invisible box as a parent and then set scaling.x to -1. Unfortunately then everything is illuminated wrong, therefore I tried to flip the normals too, but that didn't help neither. What would be the best way? Please keep in mind that there is no model that could be exported with another parameter for the left or right handed thing. Please look at the screenshot below for more clearity. Thanks!
