Note the answers to fix this issue are 'Turn off Tokenizer'
To fix this, provide an interface to force tokenizer NOT to composite the portrait file but use it as-is.
Currently there is no option to do so.
Note that this functionality exists in the token: you can override the tokenizer's token by setting the image from the token settings in token prototype, which Tokenizer does not override, but no way to override the portrait to be a particular file and not composited.
Just shift click on the portrait to open the default filepicker and by-pass tokenizer. You can also reverse this behaviour in the settings, so only shift-click opens tokenizer.
Sometimes, like in this workflow: https://www.reddit.com/r/FoundryVTT/comments/s9fkw5/in_8_minutes_you_too_can_have_animated_portraits/
