Hi eschweinhart
Lumion only provides the Tile based texture mapping, that is the square/equally proportional basis.
You can sometimes get a 'loose' approximation to what's needed by changing the Scale (only proportional so does not always suit need

). Then adjusting the Position with the X, Y and Z Offset sliders (***More button in Material Editor for Standard Material). You might need to use the Shift key to fine tune the Scale, and positions also.
Alternatively, the image needs to be mapped in the 3D modelling application, so that it has the correct UV properties when exported match the image scaling needed.
One aside question; do you require the Stained Glass Window to have some transparency, or is Opaque OK?
