... And it's about freakin' time... Oh, this thing was live ?
Here is the latest version of the RLV, at last... I've been waiting for a while before being able to release this, because there was always something that was too wrong to make it acceptable for public use. The code from the official SL viewer has changed quite a bit in the last month, and many new features have been brought to SL. The two most important ones are Pathfinding and Temporary Attachments.
I have no clue how Pathfinding will work yet. I do know the viewer has to be able to handle them, but from what I understand, for the moment every third party viewers such as the RLV is unable to control it yet. The user interfaces are there, but they are just stubs so they won't do anything. A little like mesh upload back when it was new.
Speaking of mesh upload, it seemed that the new Pathfinding stub library for third party viewers included the code for mesh upload, at least the one given by Linden Lab, which is a stub as well. In other words, to release this "Pathfinding-enabled" (with big quotes because it cannot handle it yet) meant to not being able to upload mesh once again. Unacceptable, so I had to skim through the code to reinstate the open-source mesh upload library. This explains the delay in part.
The other big new feature for SL is "temporary attachments", which means that any object is now able to attach itself on you, whether you own it or not. If you do not own it, the attachment is "temporary" : you do not have it in your inventory and it will be destroyed when you detach it or when you log off. Problem is, the viewer is not given any way to tell a temporary attachment from a regular one. Not being present in your inventory is not good enough, because your inventory could still be loading so even regular attachments would not appear. Worse, a temporary attachment could issue RLV restrictions and commands. To at least err on the safe side, this RLV will not permit an unowned object to use the @acceptpermission command to attach itself on you automatically. It will always have to ask your permission, regardless of how restricted you are. I can only recommend to be extremely careful what you allow to attach on you. I am also convinced that eventually the viewer will be able to tell a temporary attachment from a regular one, but for the moment that is not the case yet, hence this precaution.
Another reason for the delay is that I am fed up, as in really really fed up, of all those viewer crashes. It is unbearable. Unusable. Pathetic. Part of the crashes are due to the open-source JPEG library (the official SL viewer doesn't use it since it has KDU, but Linden Lab does not own a redistributable license for it so we are condemned to using OpenJpeg instead). That library is good, but has severe shortcomings when it comes to handling degraded cases such as corrupt textures, huge textures or memory allocation. All those things are edge cases from this library's standpoint, but routine from the viewer's standpoint. As the crashes are not coming from the viewer, LL would not fix them, and as they are edge cases for the library, the team in charge for maintaining the library would not fix them either. Catch-22. So I worked on strengthening both the library and the viewer myself. It is not perfect, but I have a crash rate way lower than before. This is better than nothing, I guess.
Also I noticed that when @addoutfit was active, the viewer would sometimes have trouble reattaching bodyparts after logging on, resulting in making you a permanent cloud. I tried to fix that, it looks good from the tests I ran, but I'll still keep an eye on it.
Finally I wanted to make aiming in Mouselook even more efficient. Holding the Control key down while aiming now makes your aim more precise (speed x0.25), but not as much as when you're holing the Shift key (speed x0.1). Both keys are cumulative, which means that if you're pressing both, your speed goes down to x0.025 ! Now you can score a shot when zoomed to the max !
Anyway... enough blathering. The features themselves are few but significant I think :
- added : Press Ctrl while in Mouselook to make your aim more precise but still faster than with Shift. Combine Ctrl+Shift for an extreme precision.
- added : Handle the new temporary attachments by not letting @acceptpermission automatically accept attachment requests from objects you don't own.
- changed : Strengthened the viewer against texture crashes (this is most of the work that has been put into this version actually). As a result, it takes at least an hour to crash in crowded areas while on deferred rendering ("lighting & shadows") while it took a few minutes before. There are still artifacts on textures after a while, but at least we are not crashing as often.
- fixed : Alpha textures were not casting or receiving shadows.
- fixed : Made @addoutfit let bodyparts be worn while we are a cloud.
As usual, you can grab the viewer here :

Have fun !
