(Bug 865455) CommandBuffer fails to blit Point lights' shadowCubemap

Hi everybody!

I try to copy the point lights' shadow(cube)maps into a renderTexture using commandBuffers and LightEvent.AfterShadowMap stage.
It works for directionals and spots but fails with point lights

I understand that the problems must occur because of dimensions but there is no workaround for this.

Has anyone ever managed to get a copy of an omni/point light shadowmap otherwise?

I come at the end of all the ideas i had and still no luck...

I've submit a bug with a reproducible project but no answer so far.
