[BUG-216012] Mesh Avatar with Alpha masking > 0 doesn't appear in "Edit My Shape."

[sl-service-account]

Steps to Reproduce

Wear a full-body rigged mesh avatar textured with avatar bakes and edit your shape.

Actual Behavior

The illustrations showing the extreme slider positions won't show the mesh avatar and the underlying avatar is shown (properly) as being alpha'd out, leaving the avatar to be shown as literally disembodied attachments.

Expected Behavior

The baked-textured avatar should appear in the illustrations the same way the default avatar or a non-baked mesh avatar does.

Other information

The avatar itself appears in the main view; it's just the illustrations that appear above the sliders.

Hmm this doesn't reproduce for me. I'm testing with the Wowmeh mesh body (the only human mesh body I have that's mod).

Hmmm... I was wearing a Bento-rigged full body and head from a downloadable file provided during the Bento testing phase.

I passed you "bentoHeadMesh_0" inworld - it's one of the old test bento bodies. I can't repro with that one either.

Not wearing mesh body - http://prntscr.com/iz272q Wearing mesh body set to use bakes on mesh: http://prntscr.com/iz2874

That one works properly for me too, at least on Agni - this doesn't seem to be a widespread issue then.

Hi Theresa,

Will you please pass a copy of the rigged mesh this reproduces with to Dan Linden and I so we can try to reproduce this issue.

Thanks!

I sent a copy of the body to Dan Linden on Aditi.

I think I found the issue - the body is set to alpha masking and will appear if the cutoff is set at 0 (i.e. will never show alpha'd sections.) Anything from 1 to 100 will cause it to not appear in "Edit My Shape." Given that it will be necessary for alpha masking to have a non-zero cutoff to use any wearable alphas, this is a problem.

Ahh yes, reproduced. The same problem happens in a non-BOM viewer if you are wearing a mesh body with the diffuse texture set to alpha masking with a non zero cutoff too.

On default release Second Life Release 5.1.2.512803 (64bit) - same problem. https://prnt.sc/j4dv7e https://prnt.sc/j4dvtf

This only reproduces when ALM is enabled too. When ALM is disabled: https://prnt.sc/j4e0aj

Hmm I wonder if this is essentially the same bug as BUG-4357
