Bug with "From Camera" material option
It seems that activating the From Camera option on a PBR Material breaks the roughness, even if the Roughness option underneath is checked and set correctly or after deactivating the From Camera option again.
When that happens, the roughness becomes binary (everything is 100% shiny except parts of the roughness map that were full white), and the only way I found to get the roughness back is to create a new PBR material from scratch and replace the original one.
Hey Jeremie,
Good catch. Lens Studio currently doesn't remember the state of disabled elements so when we enable From Camera, we disable Specular Envmap, and its settings get reset.
Thanks for letting the community know you were running into this issue, and let us know if you need further assistance!
Cheers,
