Rotate to Z axis up

[skiss9]

Hi, I have some gltf files exported from shapr3d, which unlike blender doesn't have the option to uncheck "Y axis up".

The files get exported as Y axis up, but I'd like to convert them to Z axis up.

Is there an easy way to do this?

I see the node.setRotation method but it moves my model below the horizontal plane, not sure what's happening there.

Thanks in advance.

node.setRotation is not what I need because I'd like the objects in the scene to be Z axis up when they have no rotation applied. It's for an interactive app and having the right rotation origin is important in my case.

If you'd like to avoid applying any transform to the nodes, then it would be necessary to apply a transform to the vertices of each mesh. The following functions could be helpful:
