Why would a mts file load upside down in scene builder? The shadow appears at the top of the mts file (which is upside down). I rotate the file right side up and the shadow follows, always staying on the top side of the mts file. How can I fix this?

The only thing i can think of is that the file was saved out of a package with right handed coordinate system. VMP and SceneBuilder are left handed, which means that one of the coordinate axis is flipped.
The easiest way to fix it is to create a mtx file with negative scale for that axis and flipping direction of back face culling for this model. Let me know if you have any problems with this.

Thank you for this question, I've been wondering where to post the same question! I would also like to add, my vet content is an animation, ( walk sequence ) from Poser 4.[EMAIL]laura2844@worldnet .att.net[/EMAIL]
