Hi Fizz,
I follow what you're saying and this certainly sounds plausible given some of the known issues with Bakes on Mesh presently. Will you provide some sample content and the script for a reproduction case. You may pass this content directly to Dan Linden and Kyle Linden.
Additionally, can you reproduce similar results using mesh content and scripted alpha updates on the release viewer immediately prior to Bakes on Mesh? That is LMR#3 which you can download here: https://releasenotes.secondlife.com/viewer/6.2.4.529638.html
This will help us determine if it is an issue new to Bakes on Mesh.
NOTE: You will need to update your viewer settings to opt-out of automatic updates in Me > Preferences > Setup > Software updates before you install the older viewer. Once done with the experiment, remember to restore these preferences.
Please press the Info Provided button when you have updated this issue.
Thanks!
What just happened?
Incorrect viewer rendering of a bakes-on-mesh texture on a mesh avatar when assigning the texture and alpha blend mode via script
What were you doing when it happened?
I'm working on the updates to the Tonic mesh bodies and other things to support bakes-on-mesh. In developing the script code for this I stumbled upon an issue where when applying the bakes-on-mesh texture to the prim in the linkset with an alpha blend mode of MASK does not work every time.
It's a bit annoying to repeat, but the steps are like this:
wear mesh, assign the bakes-on-mesh textures to the mesh with the alpha blend mode set to NONE (via script).
If you right click edit the mesh and look at the texture you'll see that it's the baked texture if you click on the texture.
Next, keeping the mesh on, assign the bakes-on-mesh texture and set the alpha blend mode to MASK with a value of 128 again using a script (NOT USING THE in world prim editor). Nothing will change. If you right click edit the prim again you will see what is wrong (I've attached a screen snapshot).
Notice how the alpha mode is NONE but it should be mask because that's what the script did (you can see that I was verifying the script behavior in the chat log - my message saying "skin alpha_mode 2..." is confirming that the arguments about to be passed to llSetLinkPrimitiveParamsFast are correct.
Now if you take that mesh off and put it back on, Voila! it will be correct and the mode when editing the prim will show MASK.
What were you expecting to happen instead?
What I expect to see is that the blend mode should be MASK not NONE as that is what the script has set.
Other information
I was trying to debug using system clothing layer alpha masks when combined with my bakes-on-mesh body and seeing strange behavior.
