Have you tried the latest version 2-24-1?
If does not work with that, can you share your model (I use sendgb.com to share files).
Hi, Thanks for the feed back I'm using the latest version but here is the model the texture is embeded https://sendgb.com/uO3Xr86H4lR
It looks like this model does not actually have a diffuse texture/material on the model, just an emissive texture (as the add-on notes mention, only diffuse / albedo texture is supported.)
I suggest either adding a diffuse texture to the model in a 3d tool like belnder or using a different model.
