strange things

[Ramjet]

Just a little word:

The position of Y axis as vertical axis instead of the usual Z axis is not a real problem, when you understand that you can use options when you export your object.

In File-> Export or File -> Export Selected you will find a "black rectangle" at the right of each Export items.
Select this black rectangle, and the "....Export Options" window will be displayed.

Un-notch the "Swap Y and Z Axes" and there will have no more problem in exporting your objects.

Yes I know, it takes me a (very) long time to understand this little clue!

At first, I must rotate my objects in the negative Z axis before exporting to .3ds or to .obj and use them in games!

My two pence.
