When I try to export to AVI or flash Tutorial 5.8finial.moho it gets about 80 frames in then Moho disapears. I tried it on two pc's. Anyone else hase this problem?
AVI and QuickTime export fine for me here, but I do see the crash when exporting to SWF. It's kind of tricky to fit 3D effects like this into a strictly 2D format like SWF. I'll get this on the bug list and see if we can figure it out.
That's quite different from the crashing issue. Tutorial 4.2 uses image warping, which is just not compatible with Flash - that's not a bug, Flash just can't handle that.
For a list of what can and can't be exported to Flash, take a look in the manual at the Reference->Flash Tips section.
