Notch - Fisheye to FullDome via Spout

I am trying to figure out a workflow for getting a fisheye camera view out of notch into our dome theatre in realtime using Spout. Ideally I could have it at 4096x4096 at 60fps. I can’t seem to figure out how to set up my project to do this, wondering if anyone might be able to help out.

Thanks,

UPDATE:

I managed to get it to work, when I choose the full 4096 in cubemap rendering Notch crashes, but it is working set to 2048. Now I am wondering, how I can output the fisheye camera vieport to spout, but still have my other views available for working on the scene, while always outputting only the fisheye camera viewport?

the fisheye camera uses a cube map to generate the camera perspective, and the cube face resolution is per face. I believe the fisheye renders 5 faces (skipping the back), and so setting each face to 4096x4096 is probably rendering a scene at 8192x12288 (or something like that). If you’ve got deferred rendering turned on, that will use a significant amount of VRAM.

If your output is 4096x4096, then 4096 in the cubeface res is also overkill. Each face of the cube map necessarily gets squashed and warped to fit the render output, so it would probably only take up ¬25% of the view space.
Rule I would use is pick a number half the output resolution, which in your case, would be 2048.

As for the update question, we don’t really support that workflow right now. If you are working within a media server or with standalone, you could network connect to the block/executable and our edits will update automatically, but from builder there is only one viewport to work with.
