Hi,
just an observation, might me intendent behavior. (or not
)
The .env creation/export works only for one texture export.
If I do the process> Open sandbox > import a .glb (to have a content loaded) > import (drag in) an .HDRI for the environment > choose scene/tools > generate .env Texture > works perfectly (the .env is downloaded).
Then if > drag in a new .HDRI into the same scene, the > choose scene/tools > generate .env Texture > is not present any more.
So need to refresh the sandbox page and do the whole process from beginning to get to export.
Not a big deal (and might be intendent behavior).
Best. Werner
