I have recently finished a full 2 hour course of videos that explain step by step how to shoot and process HDR 360 panos suitable for using in your 3D package for IBL, or just posting online to google maps and viewing with HMD.

Please find the course here on Udemy, check out the free preview, and if you would like to enroll here is a coupon for half off.
