Transform in egg and Bullet

Scripting Issues
1

I see that my .egg file have this field:

<Transform> {
		<Matrix4> { 
			3.2808398950131235 0.0 0.0 0.0 
			0.0 3.2808398950131235 0.0 0.0 
			0.0 0.0 3.2808398950131235 0.0 
			0.0 0.0 0.0 1.0 
		}
	}

I use Bullet ConvexHullShape with geom of above .egg file then my shape is smaller than my model…

I remove them or change the matrix to idenxtify matrix -> Everything ok @@
How to set nodepath of my BulletBodyNode have the same “transform” like my model ?

(I use setTramsform method, but it only work for panda3D’s position, scale, hpr - not the “Transform” in my .egg file)

This is obviously a scale transform (uniform, sx=sy=sz=3.28).

Your best choice is to get rid of scale wherever possible, for example by applying the scale to the vertices BEFORE exporting from your modeller.

Or - if you really need to have it in your egg files - after loading and BEFORE creating a Bullet convex mesh (by use of flatten-methods).

The least recommended option is to READ the transform from your loaded model and then pass the TransformState as additional parameter in the body.addShape(BuletShape, TransformState) method.

Thank you !
