Scale Scene Maintain Relative Position

[reddozen]

Is there a way to join meshes together so that even if they're scaled, they maintain their joined position?

 

Example:

I have a terrain and sepraite tree meshes. If i want to scale the entire scene down how can I make sure that the location of the trees stays relative to their original position on the terrain?

Hi, 

 

I don't know if it exists a way to do that automatically in Babylon, But i would link the tree position to the terrain actual size: 

tree.position = getTreePosition(terrain)

Something like this.

That's basicially what I'm asking. If there's a way to join the 2 meshes at a point or combine them.

To join two meshes, you can use the property "parent" on a mesh to join another one : 

tree.parent = terrain

This way, all transformations done on terrain will be done to the tree as well.

 

But i'm not sure this will keep the tree relative position on the terrain. In this case, you will have to do the work with your own code.
