Title: How to save background on exr
Post by: arqrenderz on 2019-09-15, 02:21:32
Simple topic, i want to save my background that is a 360 drone photo put on the override direct visibility, reflection and refraction of the scene, and i want to save it as it shows on the vfb, but when i save as an exr file it just dissapears, i have tried corona beauty pass, relection, refraction and a bunch other ones.
i love exr for the file organization instead of having tons of files for each render.

once you have placed the image in the override direct visibility that should do the trick. When you load the file into Photoshop did you select Alpha Data Channel: As Alpha Channel or As Transparency?

As Alpha Channel should give you the output you are looking for. If you are using a different software to view the exr file then you should find the option that is enabling the alpha by default (which will make the background either transparent or black).

THX! opening on phosothop with the free exr plugin and checking split alpha do the trick!
