It's inevitable. Any bets on how long it will be?

1. Ages ago. Around about the time alpha textures for clothes were allowed. SignpostMarv Martin 00:53, 11 January 2007 (PST)
2. Do bear in mind that my mention of a possible implementation for the 'nude patch' would be akin to hallucinating, due to the also mentioned ability to run extra-stringent checks on the server side for submitted content in PG regions. SignpostMarv Martin 01:08, 11 January 2007 (PST)

I don't think a nude patch could work anyway - the skin and clothing textures are combined on the wearer's client, then the combined texture is uploaded to the server as the single texture that appears on the avatar. That's why "rebaking" your textures on your client affects how other people see you. You could possibly just apply the same skin to everyone but you might just as well leave everyone unrezzed then ;) - Yumi Murakami

and chase all your payig customers away ? In order for us to build our business out in SL and represent our RL business inside SL such things should never be possible therefor as this is a technical wiki and forum how to further create a better client i suggest to build as much security in the client as possible ro prevent such 'attacks' on our avatars.

As I described in the Barriers to implementation section for this "feature", security such as this would have to be built into the server. Since the Viewer is now GPL, all it would take is for someone to remove this 'security' layer, and you're right back where you started, thus Linden Lab are highly unlikely to spend time implementing such a mechanism in the client. The method I described has benefits for both the main and teen grids anyway.

Aside from the odd oversight over the years (e.g. texture uploads, megaprims), all security and validation operations are executed on the server side. It fits into LL's behaviour to implement such checks on the server, and while they could, and most likely will do something alone these lines, there is unfortunately nothing you can do to stop somebody else making their client get nervous imagine you in your underwear. Or less.

• here is a quick and dirty solution ;)

Barriers to Implementation

Steps to how Linden Lab could 'disable' a 'nude patch'

1. Run a check on clothing textures including alpha information
   • Check for alpha information around the genitalia, refuse upload if check returns positive
2. Composite clothing textures server-side when avatars are:
   • In PG regions
   • Viewable from PG regions

A 'nude patch' would function by:

• somehow submitting full alpha textures on all clothes no matter what was worn (prevented by LL as described above)
• ignoring what the server says regarding skins
  • Could use procedurally generated textures based on avatar shape, and primitar type to prevent 'Attack of the (nude) Clones'
