Probe projection? Who use mirror ball made hdr maps anyway? :]
Me. To some degree. It´s not about HDR but it´s the
projection I need:
For quick´n dirty reflections we usually take a single photo with a circular lens. Take a photo, extend the canvas in PS or whatever application so it meets a mirrorball FOV and plug it into a shader supporting mirrorball projection - ready. No conversion, no stitching, no postwork for the environment at all - just one photo. Enough for reflections when you do e.g. archviz projects where the counterpart is important and would be (and should be) visible in reflections.
Right now VRayHDRI is the only way to do that in Corona afaik, please correct me if I´m wrong. I´d love to see "Mirror ball" in the Environment mode dropdown of CoronaBitmap for this reason in the future.
Good Luck
