Summary0007719: Rigged & unrigged mesh transparency rendering issue
DescriptionAll mesh, either rigged, worn or unworn, which use PNG textures, are displayed with alpha rendering issues, which show broken, triangulated faces and holes
Steps To ReproduceCan reproduce, consistently, using multiple viewers (Firestorm, Singularity).
Additional InformationI gather some Mac users have reported the same issue

Updating to the latest Nvidia driver for my system has not fixed the issue

Changing graphics settings and hardware settings (ALM, VBO, Hardware Skinning ect) also does not fix the issue

This has been an issue with PNG textures for a very, very long time, and it's an issue with the viewer (and possibly OpenGL) rather than the server. This issue predates OpenSim.

The best workaround is not to use PNG files as textures on any content that doesn't need an alpha layer. I tend to stick to TGA (TARGA) files, and save a 24-bit TGA when I don't want an alpha layer. This prevents the reported issue from occurring. BMP files are another lossless alternative that don't have an alpha channel. JPEG files also avoid the issue, but of course are not lossless.

This looks like a viewer side issue
