From 6e58c3d563b50c5797d1cfffbaec3fe82f18c2ea Mon Sep 17 00:00:00 2001 From: Master ScienceSim Date: Mon, 25 Oct 2010 14:11:47 -0700 Subject: Half of the compatibility is working. Login into a new region with old data works. Teleport out of a new region with old data works. Teleport into a new region with old data does not trigger the necessary rebake. --- OpenSim/Region/CoreModules/Avatar/AvatarFactory/AvatarFactoryModule.cs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'OpenSim/Region/CoreModules/Avatar/AvatarFactory/AvatarFactoryModule.cs') diff --git a/OpenSim/Region/CoreModules/Avatar/AvatarFactory/AvatarFactoryModule.cs b/OpenSim/Region/CoreModules/Avatar/AvatarFactory/AvatarFactoryModule.cs index 9f7ff7f..b74cdc9 100644 --- a/OpenSim/Region/CoreModules/Avatar/AvatarFactory/AvatarFactoryModule.cs +++ b/OpenSim/Region/CoreModules/Avatar/AvatarFactory/AvatarFactoryModule.cs @@ -136,7 +136,7 @@ namespace OpenSim.Region.CoreModules.Avatar.AvatarFactory { if (m_scene.AssetService.Get(face.TextureID.ToString()) == null) { - m_log.WarnFormat("[AVFACTORY]: Missing baked texture {0} ({1}) for avatar {2}",face.TextureID,j,this.Name); + m_log.WarnFormat("[AVFACTORY]: Missing baked texture {0} ({1}) for avatar {2}",face.TextureID,j,client.Name); client.SendRebakeAvatarTextures(face.TextureID); } } -- cgit v1.1 From 9132e251aa0d0d7395dc4868fd57799dd679cdb7 Mon Sep 17 00:00:00 2001 From: Master ScienceSim Date: Tue, 26 Oct 2010 12:53:15 -0700 Subject: Made the check for texture assets asynchronous.
