Indeed… It’s possible to change the color depending on what object has been chosen. But it won’t work with two or more different objects outlined simultaneously.

the fuselage material should be non-transparent to render your transparent decals properly over that material at any angle.

the problem is in your logic. the variable Szinek is undefined initially and it’s never defined afterwards. you set value for roofszin but for some unknown reason you use undefined Szinek (instead of roofszin) to get corresponding texture name from the dictionary. the result will be undefined and nothing will happen.

then you’re on your own

remember from where you took objects. use some variable (a dictionary) to save initial parent objects for picked objects.

put them back from where you took them

Is there a way to parent it back to the main scene

they are already parented to the main scene. objects will be parented to Scene if you leave the second argument empty. But initially (before grabbing) they were parented to Display1.

which would force all shaders to be compiled

all material shaders are already compiled on loading.
