Thanks Mike for the details you sent me. After more tests, I found a stupid regression I programmed: the problem is about angle set on textures. They are simply ignored when you try to set an angle different from 0 in the Beta 7. But fortunately, angles set on textures with a previous version are not lost when .sh3d files are saved in Beta 7 (both in [font=courier new]Home [/font] and [font=courier new]Home.xml[/font] entries are correct).
I'll deliver soon a new Beta version.
