Yes, but didn’t work. Found a fairly crude workaround: I changed the disembodied camera to a scenecapturecomponent2D. This renders a texture which is applied to a plane which sits in front of the camera. It works, but I expect it will be extremely expensive once the scene becomes more complex.
There are two issues with the plane: It catches light, so depending on where I stand in the scene, the brightness of the image changes. Also, the screen is visible inside the projection. Is there a way to make the plane not catch light or something like that? Maybe make it slightly emissive? And is there a way to make the plane invisible to the scenecapturecomponent2D?
For those interested, it is very hard to manoeuvre disembodied like this. The orthogonal camera removes the depths so it’s makes it even harder. So far I haven’t gotten ill, but I haven’t spent more than 5 minutes at a time in there. I think if I can get a rigged mannequin in there it will be easier to orient myself as I will be able to see how might my body is compared to everything around.
