[Updated] Issue with texture-animated mesh water ripples - caused by a bug or a feature in 7.1.10/7.1.11 versions of official SL viewer & Firestorm?


Recommended Posts

Hi all,

I have this game that uses rippling water effects in a mesh object that plays a texture animation. Since a new viewer update, this water mesh is no longer semi-transparent, but grey, breaking the water animation effect.

In the picture below, on the left, the animated, rippling water is shown as intended, using the Firestorm 7.1.10 version. On the right, the same object is shown using the official SL viewer, version 7.1.10. Note that the frame on the right also looks like this when I use Firestorm version 7.1.11 (the water is also grey/broken).

I could not find a similar issue in other texture-animated objects, but those all used an alpha mask. The water above uses alpha blend.

I've excluded that it's a network/texture-loading issue. All the relevant PBR textures have fully downloaded.

Did something radically change in the rendering of PBR from the transition of official viewer 7.1.9 to 7.1.10 and, similarly, from the transition of the Firestorm viewer 7.1.10 to 7.1.11?

Would it be a temporary thing that's being addressed in future versions? Because it seems that the change in the way the object is being rendered has now broken my game. This has never happened before in the 16 years that I'm in SL.

[Update]

I've narrowed it down to a rendering bug. It only happens when an object has both PBR and Blin-Phong materials. (See image below.) I've submitted a bug report on the feedback page.

Please please 🙏 upvote to get this fixed.

And this one too, which is somewhat related, but IMHO even more important:
