Craig, thank you for the huge amount of research you’ve done on this topic and for sharing! I don’t have the camera, but would like to convert the already stitched 360 jpgs from the Theta SC2 to exr backgrounds for my 3D rendering software (Enscape3D and Twinmotion). I’ve tried the PTGui Pro app and it doesn’t seem to recognize what kind of stitched file types they are. Any suggestions?
