Thanks Tim,
no luck.
I tried saving the 3ds from archicad to 3dmax (camera openned ok)
When importing the 3dmax '3ds' to cheetah the same problem occurred.
Looks like the camera location and target is moved.
I have just been testing HDRI and some of the lighting tools in cheetah, we are very impressed.
However we are constantly revising our 3d models in Archicad so the 3ds camera export will be great if it can work.
It will be great if archicad could export a cheetah file just like artlantis, pirensi or electric image does.
thanks again
Ian
