 Description  « Hide
I'm seeing graphic issues on animated textured prims when viewed from a distance ... see sample JPG file (s).

The sample is at my home reef at 172, 176, 10 at Nomanisan Bay, on some Fish I built. They are 2 prim fish (1 prim sculpted body and 1 prim Box "fin". The fin has an animated texture which steps through 4 frames in the animation.

However with the WL client, when I view the fish from a distance the prim with the animated fins is displaying the entire texture (all 4 frames). I assume this is some sort of optimization to not animate at a distance (which is a great idea), however it needs to be implemented a bit better ... ideally display say just frame 1.

The animation code i used is:
llSetTextureAnim(ANIM_ON | LOOP, ALL_SIDES, 4, 1, 0.0, 4.0, 0.5);

Steps to reproduce:

  • View an animated textured prim from distance.

Confirmed on my end too. When you look at a prim with an animated texture from a DISTANCE, you see all frames. Once you zoom in the texture is displayed correctly.

Why hasn't anyone else reported this as a problem? I think it's awful... I get it so much, especially with fire textures. I'm surprised this isn't one of the most popular problems on here...

And a lot of textures that are animated (even if it's just a simple rotation) don't even animate. Take the Alteran stargates for example. The shield on it doesn't even rotate in WindLight, but if you select the object you can see the texture has moved.

This needs fixing!

Edit: Just uploaded an image of an example of the fire. May upload more in future when I come across it.

Most likely dupe of VWR-3101.

Hi Torley,

Thanks for looking at the bug.

However, I don't believe this is the same issue / duplicate as VWR-3101. I do understand the eagerness to close bugs, but this is different.

This is specific to ANIMATED textures, and has nothing to do with opaqueness etc.

The issue here is that the entire animation texture (all frames) is being showed when viewed from a distance - ie. the viewer is not clipping the animation texture to animate it, or if animation should not be displayed from a certain distance, then at least still clip the texture and show only the first frame.

Its as if there is optimization code in there disabling animated textures running when the viewing distance is very far, but instead of drawing only the first frame of the texture while animation is disabled, its drawing the entire texture - ie. all frames.

Potentially this means animated textures are crippled, and I agree with Ethari Hallstrom this is a serious issue, and am also extremely surprised its not being fixed already.

I'm moving this up from Normal to Major as its been around a long time, and is quite serious as it prevents proper use of animated textures.

IAm: Can you please check today's WindLight update and see if it made a difference for you?

Thanks Torley,

I don't see this issue anymore, so I'm assuming it has been fixed in one of the recent Windlight viewers.

If anyone still has it, let me know and I'll re-open it, but I'm not seeing it.

thx
