Hi Puybaret,
thanks for your detailed answer. Puuhh, I didn't thought that this could be such an effort...
Hmmm...I think I know what you mean.
What about an additional option like "Start at bottom" for each wall side:
The dialog will be still not be overloaded with too many options and you can freely choose where to start drawing the texture.
Inside walls should have this new option checked, so that the texture will be painted from "(start of current level)+floor tickness" and outside or exterior wall sides the option will not be checked, so you start painting from "(start of current level)+0".
...Arrghh... should have read your second post completely!!! But I see that both of us got to the same solution: The new property.
Do you really think it would be too overloaded?
Imho I think that this would make it much easier for users creating a multi-level object insted of calculating the texture offset for each level ((level-1)*(wall height of level+floor thickness)".
Sample of dialog with new option (multi-language ;) )
