It's still crashing...
Now I cannot get Artistic Renderworks to work at all without crashing.
I now have another problem;
After creating a 'model view' in a separate layer and viewing the 10 or so combined layers I have drawn, there appears to be a problem with consistency in the layer 'stack'.
For example - Sometimes the roof layer will be in the correct position as stated in it's 'layer Z' value and sometimes it will not. Also, if I then try to change it's height (z) within the layers it will not 'always' move. The only way to get it to move is to delete the model view and create a new one - Although this only works 50% of the time.
This is very frustrating as there does not appear to be any 'constant'. Eg/ If I create a model view with only 2 layers (including the roof) it will be in the right place...? Then if I include all the layers it will not.
What am I doing wrong?
