Hi, When I adjust the textureIndexWindowZ values, the dynamic preview shows that changes are updated along X axis of a Generic Building and vice versa. I believe this is incorrect. textureIndexWindowZ should affect the Z axis, and textureIndexWindowX should affect the X axis. Please advise. Also, is there a way to stop the dynamic preview from rotating constantly? The reason I need a stationary view is because I need to count the number of floors, and the constant rotation makes it very difficult to do Lastly, I want to thank Arno for this wonderful program, I found it very useful indeed! Regards, Dodo.
