Scale Texture & SetTextureAnimation...

I've been experimenting with llSetTextureAnimation on a lag-reducing mission. Ultimately, I want to replace any instance of llSetColor I have with llSetTextureAnimation.

My question: Is it possible to scale a texture (repeats per face) while using llSetTextureAnimation?

I seem to be getting myself into a catch-22...

I have a 10x10m square that is a flashing puzzle-piece dancefloor using llSetColor. The texture on the prim is repeated 4x4. I can use llSetTextureAnim with a texture split into colored frames to achieve the same effect... but its scaled all wrong.

If I scale the texture in photoshop ahead of time - so that I don't have to scale it in SL - I end up with a *gigantic* texture with a huge load time.... creating a new lag problem.

Anyone have any suggestions, considering my goal to reduce lag? Also - given the huge texture size - am I really better off using llSetTextureAnim over llSetColor from a lag persepctive?

Thanks!

I've worked *a-lot* with llSetTextureAnim. Let me make sure I understand your situation before trying to help. You have a single prim, 10m x 10m in size, that has a grid pattern on it that is 4x4 squares(?) each with a differerent color and you want to have those 4 colored squares change color?

llSetTextureAnim() seems to override any texture scale settings, unfortunately. The only exception that I'm aware of is if you're using SMOOTH type animations, and set the x and y frames both to 0. Unless this has changed recently?

Travis, would you mind posting a picture of how it looks and how its supposed to look?

Glad to, guys - thanks for the help I'm at work at the moment - but when I get in game later I'll upload some pics.

In brief tho - Yes, I have a grid. This grid is 5 squares by 5 squares. I use repeat on it - so that in world, it appears as 20 squares by 20 squares.

If I try to animate this - the best I can do is the original 5 square by 5 square texture.

I can go into photoshop - and just make a 20 square by 20 square texture myself - but the filesize will be 4x as large.... unless I significantly drop the original resolution - which makes it look like crap.

I'll post some pics later...

My advice: Overlay a prim with this in it over your textured prim. Alpha the color-changing prim.

Lag redux at the expense of an added prim. Useful?

Possibly.... Thanks, Jeff My only concern here, is that from what I've heard, alpha textures introduce a whole set of new lag concerns on the client side. The question is - if I can't solve the problem completely.... Is the framerate hit in using an alpha texture not as bad as the server hit using llSetColor.

Actually, my original intention was to make each "frame" a different color - giving the flashing effect. But as you know - doing it that way gets me back to the scale problem.

What I've been attempting to do:

-Get rid of all llSetColor function calls
-Get rid of as many Alpha textures as possible
-Get rid of as much hovertext as possible (Client updates?)
-Reduce the number of textures I'm using
-Reduce the resolution of the textures I'm using

Ok - as promised - here's a couple snapshots of what I'm trying to do. The first picture is with scale, the 2nd picture is without scale.





Gah - I can't seem to upload attachments Never had a reason to do it until now

I think all of your concerns are valid. However, I don't think using textures set as alpha one time cause lag - on the other hand, setting the alpha multiple times, via llSetAlpha, will cause several sim updates and lag.

Another pro tip is to use the texture manager in the Debug menu. That will usually give you the stack memory your texture is using, allowing you to better regulate your texture resolution.

And, thank you. I'm glad to see someone do something like this.

I ended up just dealing with the lack of scale. Its actually doesn't look as bad as I thought it would - so probably just going to leave it that way until I come up with a better texture.

Thanks for the help eveyone - Jeff... didn't know about the debug menu option - that's gonna come in handy

For the purposes of the thread - if anyone has any ideas on how to overcome scale issues in general when using llSetTextureAnim, please post 'em here for the benefit of everyone else
