A new release of RLViewer is out. You don’t really need it… no, I’m being nice. There is a problem with version 22.214.171.124 and version 126.96.36.199 is sort of a fix. Or you can just follow directions in the announcement post and fix your currently installed 188.8.131.52 version viewer.
See: RestrainedLove Viewer 184.108.40.206. You need to copy 5 files from the SL Viewer install folder over to the RLV folder.
Or download the new RestrainedLove Viewer 220.127.116.11 version here.
There is also a problem with Materials in the viewer. It breaks InvisiPrims… REALLY!!! I thought that had been broken in the SL Viewers forever. Whatever, Marine Kelley has been providing support for InvisiPrims because some RLV products need them to hide parts of the avatar under script control.
It looks like Marine is not going to be able to cobble up a working fix. Marine is planning to change the products to operate a different way. So, I guess start writing off InvisiPrims permanently.
