Appliers are the scripts that allow you to wear clothes over mesh attachments. Those using Tangos and Phat Azz and similar attachments know about appliers.
The problem with appliers is many of the creators of mesh attachments are using their own applier, a custom script they developed. If you make system clothes via the clothing templates, you get a template from the mesh attachment maker and make textures for the attachment. It then looks like your clothes are fitting over the attachment.
The problem is everybody seems to be making their own scripts. The result is there are incompatibilities in how appliers work and how to make textures for the attachments. A big peoblem for designers is in knowing which face number is to be used for a texture. Is face #1 the breasts or butt?
There is resistance to making the Applier scripts open source. The scripts change the textures by sending a message on a hidden chat channel. If griefers knew the channel, they would mess with your clothes.
Another problem foreseen is someone creating a general purpose, but no mod script, to give out for free that harvests avatar information. The harvester would know the avatar is into buying mesh attachments and thus the owner would get great targeted marketing information.
Thus the idea is to use a communication encryption process that can be open source rather than a channel obfuscation technique.
An objection to open source is that anyone can them make a copy of the script and mod it to harvest texture UUID’s. It would then be a way to steal textures for use by other sellers that did not buy them.
I don’t see a good all around solution. Dishonest and sick people make it hard to create a simple solution.
In the SL Forum Felicia Silversmith is proposing a standard for appliers. See: Mesh Body Parts Standard (MBPS). I’m not recommending this standard, but I do think some standard would make mesh attachments with appliers more popular. Add your ideas to the thread and discuss the possible problems and benefits. This might start designers moving toward a standard.
There is script published in the thread. It is missing the channel calculation part.
Let me know if you know of a better standard or way to handle the Applier process.

Personally, I think just having a standard for how faces are used and which textures goes where would be a big help. But, I don’t expect this to be worked out any time soon. There is just too much diversity, which while chaotic is a good thing.
