Hello,

After fusion two models I got the new .pth file but there's no index generated file, I don't know if this is a bug or as designed but I think we need an index file after fusion for sure.

The fusion model already does not have an index file, and the index file is not suitable for the fusion model

+1 and what is the point of fusing the models then? As far as I know, .pth file without the right .index file is not usable, right?
How can you combine two models to create a new voice?

When the index slider is 0 (i.e. index is off), selecting only pth is possible for inference (including the fused pth).
