Viewer Bug Reports

Blinn-Phong textures with alpha channels appear excessively transparent in the PBR client, with thinner alpha edges. Adjusting the exposure to the lowest setting or changing environment settings doesn't help. This issue affects many products, and the only solutions are to double the layer or make textures more opaque and have two versions of the same product included with the purchase. However, this causes inconsistency for users who don't use PBR, as they will see the items differently than PBR users.

Create a simple cube (mesh or prim) and scale it to 0.3, 4.0, 4.0. Create another cube, scale it to 4.0, 4.0, 0.3 and place it on top of the first one. Set the sun azimuth so that it shines onto the wide side of the first cube. Move away from the objects and observe that the shadow changes; there is now a fully lit band of light directly underneath the second object. This seems NOT to be not related to: • Materials/PBR -- adding a PBR material does not change this behavior. • Geometry -- the objects are watertight. • LOD -- a mesh cube with all LODs using the full geometry behaves the same. • Physics Shape Type -- Convex Hull and Prim behave the same. I have found only two factors that affect this: Top object thickness -- the effect kicks in farther away with thicker objects. The Draw Distance -- the effect kicks in farther away with lower distances. Interestingly, moving the top object up so that there is a gap between the two object changes the behavior and reduces the effect; see the attached image. PS: I realize that this may not technically be a "light leak" -- but I couldn't think of a better term. PS 2: I have tried to think of ways of designing around the issue, but I don't think there are any realistic options. Most non-trivial structures will encounter this issue in some form or other.

Just some observations about PBR: It is killing many of of our lower resource friends because their hardware cannot run it. It breaks many EEP settings we like. eg. I am at SLB21 event and my normal Nam's EEP flashes from dark to light. No control over some annoying local lighting except by trying to find source to derender. This stuff is pretty if you have hardware to run it but those that do not will be lost and I am afraid that will be many residents. I hope there will be an alternative for our many lower hardware resource friends.

Create a reflective object, like a sphere with 1 metallic 0 roughness Look at it from some distance Zoom in really close It turns black based on the camera distance

Trying the new PBR Firestorm. But textures stay gray when I have "too much" to load on a sim. Either some stay gray seemingly forever, or any I cam away from will unload and seemingly NEVER reload once I cam back to myself. Go to a region with a lot of object and/or avatar textures at ground level. Cam around, try to load as much as possible once your draw distance has stepped up. I'd test this on the SL Viewer, but I'm on Linux and don't have a Windows or MacOS machine to test on -- and I'm not sure if Wine would be supported for this. Also, forgive me if this is in the wrong place. I asked in the Firestorm group and was told to report this here.

Direcitonal inputs are noticably delayed and/or inconsistent in PBR viewers compared to non-PBR viewers, said delays being most noticeable when operating vehicles. Delays in inputs can result in key-presses that are longer than intended, or in some cases may result in no input being registered at all (the latter most notable again while operating a vehicle). To test for the bug, it is recommended that the tester be proficient with vehicle operation, namely on the grounds of consistency, and that the tests be carried out on a closed circuit (and optionally one with a timing system). Recommended testing locations: LC Racing Circuits: http://maps.secondlife.com/secondlife/YToub%20System/95/65/3931 Racers Island: http://maps.secondlife.com/secondlife/Racers%20Island/6/7/385 Free race-ready vehicles ideal for these tests are available at the landing points. The bug has so far been tested and discovered in the official LL viewer, Firestorm viewer, and Alchemy viewer. It is yet to be known if it persists elsewhere, but is highly suspected of being the case. (This issue currently threatens the existence of racing communities as it has become vastly more difficult to safely control their vehicles)

This is very much the same as what has been reported in third party viewers (TPVs) ( https://feedback.secondlife.com/bug-reports/p/textures-stay-gray-in-firestorm-viewer ) but it affects SLV too if you run Release Candidate Atlasaurus - 7.1.9.9620320242 It doesn't affect the SLV release version but does affect RC Atlasaurus - 7.1.9.9620320242 It was initially thought to be a TPV issue but it recently occurred to me that the SLV Release is at 7.1.8 whereas most of the TPVs are at 7.1.9 and they have this problem. And now testing in SLV 7.1.9.9620320242 it is exactly the same. To reproduce, use the viewer's default settings, on a Mac. In my case I am using a MacBook Pro with an M1 Max processor. Go to an object and texture heavy region with draw distance at around 128m Fly or cam around so a large number of textures are loaded Eventually some textures appear to stop loading / show as blank grey. This also affects textures on HUDs and images in profile and group floaters, and hud icons show as grey too. Additionally, textures that were previously loaded and should be cached will show as grey when relogging or TPing back to a location where they were previously showing. --- Note As per tests done on TPVs, and thanks to others, this can apparently be remedied by setting the debug setting RenderGLMultiThreadedTextures=TRUE . This appears to work in SLV too, but I do not deeply understand this debug flag or know whether it might cause some other unintended effects.

To Reproduce: Rez two prims and place them next to each other. Place a glTF material on adjacent faces on prims. Set texture mode to Planar Ensure both texture transforms of both faces do not match.
