HELP! -Tiling FlipBook textures?

CasperNilsson

Is there any one who knows how to tile a FlipBook Texture in UDK?
http://udn.epicgames.com/Three/FlipbookTextures.html

I have a spritesheet with 64 tiles ( 8x8 ). Problem is that the tiles are tileable, but the Flipbook texture in the material editor will scale the image as if it was a regular texture. A scaling of say 8.0x8.0 with the TexCoord will show the whole texture, and also pan it with 1/8 per frame. if I scale the mesh UV outside 1:1 the same thing will happen.

Is there any solution on this? I believe the old half life engine could do stuff like this, but in this high tech engine it seems fucking impossible.

Thanks in advance

Yes, UDK does it too. Easier to just send a link to the sample file. Check out my Link Disco Floor.

The problem is not to create a flipbook, the problem is to make the animation to repeat itself when TexCoord won't work.
Problem is that it will show up as the whole texture if I add higher value to the TexCoord node. Only solution I found is to subdividing a plane and overlay every new face to the 1:1 uv space. problem is that I first of all don't wan't extra geometry, and also that with a FluidSurface Actor i can't control the uv map to do this.

Sample how it looks, this is a 64 tiles "caustics" texture, where every tile can repeat itself in xy.
You see all I want is to get the first tile to repeat itself, as that one is changing when the flipbook animates it.

Add a TexCoord node to Lamonts exemple, and set it to 5.0,5.0 and you get what I mean.

FlipBookUV <- Frac <- TexCoord * Constant2Vector did it.

Huge thx to SolidSnake at #UDKC @irc.gamesurge.net

I followed this and it works great but I have a problem with seams;

Thank you! I'm so glad there is a workaround for this.
