imported blender .babylon mesh/scene axis' off

Did you try the debugLayer I shown ? It clear helps debugging

Yea I have looked through it but I do not know what to look for, I've been looking for like pivot point or something.

So if I choose the imported mesh that I want to rotate then I click the wrench, it shows the x,y,z axis' for that mesh to be off the mesh.  I think this is what dbawel was talking about fixing but I couldn't figure out.

 

It also seems as though the axis' of that mesh are just points since they don't really have length that I can tell.  if they do the length is small.

It also looks like the Y and Z axis' are switched with each, like they would have been in blender.  Yet when I rotate around the y or z it rotates around the y non matter what... well the up down axis...

 

rotation isNonUniform is true... but thats read only.

Using 

            meshes[0].setPivotMatrix(BABYLON.Matrix.Translation(-1, -1, -1));

did not seem to change where the object pivots relative to itself but relative to the world.

if I use:

                meshes[0].rotate(BABYLON.Axis.Z,1,BABYLON.Space.BONE);

or

                meshes[0].rotate(BABYLON.Axis.Z,1,BABYLON.Space.WORLD);

It will actually rotate around a Z axis, but If I use:

                meshes[0].rotate(BABYLON.Axis.Z,1,BABYLON.Space.LOCAL);

It does not rotate about a Z axis, it rotates about a Y axis (still not at its centre, off to the side)

Thanks to @JohnK we have an extensive doc on pivot:

Thanks for all the help guys!

But I figured out my own "hacky" way...

https://www.babylonjs-playground.com/#LJPRIN#8

Heres how I did it, 

Assume the red cube is the trouble, the meshes[0] that has its pivot point off its actual mesh.  So then I make another cube(called sphere) and I put that cube on the position of the redCube.  So we have two cubes one cube is red and the other is grey and not touching the red one.  then I set a cube to when the actual mesh seems to be and make it the parent of the grey cube, and I make the grey cube the parent of the redCube (not sure why I couldn't just use one cube and make it the parent...).  Then I rotate the green cube and it make the grey cube orbit it(kinda).  This makes the redCube Turn since its origin point it moving. 

 

I think, point is it works...

 

I will still look into this docs to see if there is a better way to do it.

 

Thanks everyone,

DD

As long as it works, this is cool. I'm a pragmatic

Haha yea me too a little..

Im still going to try to make this a better system, this way I need two extra meshes.  Just for rotation, so I'm going to find a better way possible.
