I'll investigate further and try to find a place where would be better place to update the id - to fix the current models

[gastoner]

The hash would be great. On Windows it works without problem because the path does not contain "/" But I would imagine same problem on Mac with the Routes

[gastoner]

ModelInfo have sha256 optional attribute - so during import I would compute sha and store it to the model and use it instead of path inside the id

[benoitf]

it can also be a hash of the id (or the id is becoming a hash of the file (but it would take time to compute as it's large files)

[gastoner]

Do we even want to have the hash IDs in downloaded models? I assume that yes, to be unified

[benoitf]

PTAL @jeffmaury

[gastoner]

@jeffmaury you have to import the model again

[gastoner]

@benoitf It should be affecting only newly imported models
