Avatar Character and Clothing are at partial (Clothing, Tattoos) or full (Avatar Skin) transparency when feet are touching any object or the terrain while Windlight Basic Shaders are ON and/or Foot Shadows are ON. This affects the Avatar Skin, Tattoos, and Clothing ONLY, this does not affect Avatar Object Attachments, Avatar Eyes, and Avatar Hair. In Flight or Jump, the Avatar and Clothing will return to full opacity until Feet (and ONLY Feet) touch any object or Terrain. Any other part of the Avatar can touch anything and retain full opacity. Going into Appearance Mode will restore full opacity WHILE in Appearance Mode ONLY. Disabling Foot Shadows will restore full opacity without the need to reduce Windlight features, however Foot Shadows are defaulted to ON on a normal install. Foot Shadows also resets to ON on program exit/start. (Advanced->Rendering->Features->X Foot Shadows Ctrl-Alt-F5) Disabling Basic Shaders while Foot Shadows are still on will also restore full opacity, however that reduces Windlight Features (Edit->Preferences->Graphics->Quality and Performance->[v] Custom->Shaders:->[v] Basic Shaders) This occurred when i installed a new ATI Radeon HD 2600 Pro AGP card. This may be something that affects Radeon HD Series but not the X1k series as this did not happen with the X1950X AGP card. ADDENDUM ------- While Foot Shadows are off, even though my own Avatar was restored to full opacity, OTHER AVATARS were not, HOWEVER, panning camera to where my own Avatar was completely off screen other Avatars would be restored to full opacity, then when any part of my own Avatar was back on screen, other Avatars would then revert to skin transparency and clothing/tattoo translucency . EVEN MORE ------- Disabling Volume, which eliminates all primitive objects (except Linden Trees and Plants) will restore opacity of ALL AVATARS, however all attachments, being primitive objects, are hidden If Foot Shadows is still ON, avatars appear to have flat black rectangles on the bottom of their feet Toggling Foot Shadows while Volume is OFF has NO EFFECT on avatar opacity. (Advanced->Rendering->Types->X Volume Ctrl-Alt-Shft-F9) ANOTHER ODDITY ------ At certain positions and viewing angles, much like disappearing alpha channels at certain texture rotations and viewing angles, the sky blanks out. Although Windlight and Classic clouds still render, the blue sky becomes white.(daytime) and black with no stars (nighttime). This appears at first random, but it seems to happen at the same points/rotations/angles... IOW, while walking or turning, the points at which the sky blanks are consistently reproducible, but pinpointing places or patterns is near impossible. Disabling Atmospheric Shaders will unblank the sky, but reduces Windlight features (Edit->Preferences->Graphics->Quality and Performance->[v] Custom->Shaders:->[v] Atmospheric Shaders) LINDEN WATER ANOMALY ------ The translucent avatar hides Linden Water. You can see the terrain and objects through the avatar body like a window. Zoom in real close to the body and pan the camera around, you can see Occlusion Culling in action, but having a rather hard time deciding what to do.. reacting to the avatar's idle movements. I would think occlusion culling to the avatar body is unnecessary. Just idle all the calculations that must be involved culling and re-rendering. THE TELL-TALE SIGN? ---- Hardware Skinning and Avatar Cloth are greyed out Connection? (Likely) (Edit->Preferences->Graphics->Quality and Performance->[v] Custom-> Avatar Rendering:-> {#] Hardware Skinning) (Edit->Preferences->Graphics->Quality and Performance->[v] Custom-> Avatar Rendering:->[#] Avatar Cloth) Oh WOW!! ------ Enabling Anti-Aliasing either in Catalyst OR in SL 1.20.0 at NO LESS THAN 16x will restore full opacity to ALL AVATARS.
