Coordinate system

[LJS]

Hi all,

Just joined the forum so I'll start of to say goodday to you all first. Am trying to set up a big world full of neat stuff. DUH. The bigger I can get it, the better it would be.

As second, thanks to all who made this engine come true - fiddled with it alread a while ago as first 3D engine. It only looks as the least attractive one at first glance. But in my oppinion, it's the best I could find. So far for the kissing up part.

As I walked a path I have a question regarding the coordinate system and - in my case - Blender.

What 'handed' system does Irrlicht use?
My guess is left handed.

What 'handed' system does Blender use?
Left too I guess.

Main question:
How to set the forward and up in blender while exporting to use in Irrlight and where that object (.obj, .x, .md3 or whatever) comes into Irrlicht with a rotation of 0, 0, 0 and facing the right way, i.e. facing Y;
- I build with Y as forward axis and Z as up axis in Blender
- have it's rotation 0, 0, 0 in Blender too

edit
And which axis as forward would Irrlicht works best with, if any?

Very basic questions but this part is real confusing me.

Irr uses Y up like every other 3d engine Z up is some weird modeler convention.

Irr is left-handed yes.
