I really need some help! I have saved a image in a HDR file to load into Fusion 360 and when I try to upload the image into Fusion 360 I get the response saying - error 'The content of the file should be stored in Latitude/Longitude format with an aspect ration of 2;1.'
Can someone please please help me and tell us how I do this?
I believe it is more to do with Fusion 360 required format of HDR image, Take a look at this discussion Creating Custom Environment for Rendering in Fusion 360 - Autodesk Community with helpful suggetions.
Let us know if that helps.
