How much is the scale in irrlicht?

Hi all:
I load a 3dmax module by irrlicht, and the module displayed in the screen seems to be stretched by a scale. I wonder how large the scale is and where I can change the scale.
Thanks a lot!

This is a question that comes up a lot, but has an easy answer...
1 unit = 1 unit
Depending on the size of the environment you want, 1 unit could be 1 foot, 1 meter, 1 mile, or 1 cm (whatever you want)

If something doesnt "seem" right you can modify the cameras FoV, apply a scale to the object in irrlicht, or just scale it differently before exporting.

There is no "scale in irrlicht" its all upto you... and what fits best.

One thing which can happen is the relative transformation of parent and child having scale. This would lead to an amplification, because the child's scale would be scaled by the parent's as well.
Another thing which can happen is a magnification due to the FOV settings of the camera. If you use very small values, the images is enlarged due to the camera values. Same as what happens with real cameras.
Not sure what you're talking about, amybe just experiment with several scenes and settings first.
