Spherical texture projection in Arnold

Hi there,

I'm trying to made a projection from a spherical texture to a mesh.

First, I rendered a Frame of my scene with an "ArnoldCameraSettings", the camera_type was "spherical", so with this, so basically I baked a spherical dome from my scene.

Then, I tried to project the baked dome to the environment geo, using a simple "camera_projection" shader, using the same camera that i used for the dome render, but I figure it out that Arnold doesn't support Spherical camera type's as projectors.

so after this failure, I'm trying to use an "uv_projection" shader, with the projection_type set up as spherical, also in the matrix values I'm using the world position that I have in the camera that i use to bake the dome, but it doesn't match...(not even close)

is there anything that I can do to archive a spherical projection in Arnold?
