Again, appologies to the old hands if this is a simple question.

I am playing around with IBL in C6, and I was wondering if my theory about creating IBL for the exact scene I am working on is a possibility.

I havent tried yet as I am lacking all the skills to do the job, but I want to know if I am on the right track.

If I wanted to set up a scene that containes something shiney, lets say a car (I have watched Marks dark arts tute with the IBL) but instead of reflecting random stripes on the car from a photoshop hdri image (like Marks dark arts tute), could I create an image/render using C6 spherical camera placed in the center of my scene to create an image that can then be used so that the reflections actially imitate the scenes surroundings?

I guess the steps would be:

  1. Set up the scene and place the regular lights, spots props or whatever.
  2. Insert the spherical camera, hide the shiney vehicle (that was in the center of the scene so its doenst show refelctions of itself) and create a render from that camera.
  3. Use photoshop or similar to convert that render into hdri image.
  4. Use the image in the scene Background-HDRI to ensure the shiney object in the scene has the correct reflections from the scene.
  5. Adjust the scene non hdri lights to obtain correct or realistic levels.

Am I talking nonsence or is this an acceptable method to creat scene lighting and realistic scene reflections?
