When importing static mesh from USD file then it has the wrong amount of UV channels. Selecting a UV channel shows an empty area in the viewport.
Regression: YES - not reproduced in 4.25.3 production
In order for this to work the models st primvars must be changes from float2 to texCoord2f. After that UV channels should import properly
UV is shown empty. There are only 1 UV channel.
UV match expected result (see attachments). There are 3 UV channels.
