[BUG-4330] Transparency is not transparent on some worn rigged mesh when ALM is disabled. #13186

Open sl-service-account opened 10 years ago

This bug does not reproduce with all rigged meshes. I have not yet worked out what is "special" about the meshes it does reproduce on.

Steps To Reproduce

  1. Upload the attached dae file with no rigging. Default upload settings should be fine - name the uploaded mesh "Lizard not rigged".

  2. Upload the attached dae file again, this time with rigging - I used the following settings:

    • Physics tab: Level of detail - Lowest.
    • Upload Options tab:
    • Scale = 0.2
    • Z offset = -0.187
    • Tick "Include skin weight"
    • Tick "Include joint positions"

    1. Name this uploaded mesh "Lizard rigged"

    2. Rez both the rigged and non rigged lizards inworld and set both to have transparency of 60 - Edit -> Texture tab -> Transparency -> 60

    3. Take copies of both meshes into your inventory.

    4. Wear the fully body alpha "Invisible avatar" from inventory Library.

    5. Wear the non rigged lizard and observe if the mesh is transparent with both ALM enabled and disabled.

    6. Wear the rigged lizard and observe if the mesh is transparent with both ALM enabled and disabled.

    Observed Behaviour

When ALM is enabled

When ALM is disabled

Heya, Whirly, can you try dropping the attached shader into your build and verifying this is a fix for you too? (I'm pretty sure it will be, but I want to test on your GT230 in case there are GL 3.3. gotchas).

Heya Graham,

All fixed with that shader file :)

Hm, I tried to either reproduce the bug or verify Graham's fix with 'Second Life 3.6.13 (284995) Dec 18 2013 21:41:44 (Second Life Release)', but the attached 'LIZARD.dae' mesh is not detected as being rig-able in the 'Upload Model' floater - "Include skin weight" and "Include joint positions" are both disabled under upload options.

Whirly, if you still have the rigged lizard, could you send me a copy? Aditi or Agni both work for me.

Heya Maestro,

The attached dae is rig-able, but remember if you upload a dae as non-rigged first, you need to delete the slm file before you can upload the same dae as rigged or the skin weights & joint positions options will be greyed out (not sure if this is a bug but it has always been this way - filed at BUG-3828 anyway ).

On Second Life 3.6.13 (284995) Dec 18 2013 20:23:18 (Second Life Release) I uploaded the attached dae rigged and passed it to you from my alt Kippy Adored on Agni.
