I have a problem with rotating my HDRI is loaded in my environment (8). I used CoronaBitmap to load the HDRI. When i rotate it with 'Angle W’it seems to rotate (not in the correct axis of course). But using the U offset nothing seems to happen. I use Corona 1.5 with 3ds Max 2017.
Hi. Just tested it, and here everything works as expected in both viewport and IR (same as when using 3dsMax bitmap loader). Remember that the U-offset values are not showing degrees but decimals where 1 = 360 degrees.
