Texturing with an Animtexture

| I have a cuboid (build in code) where each side is a quad of two triangle, vertices are not shared among different quads. I'd like to texture each quad with a different 'frame' from an animtexture. Is this possible? Or do I have to manage the u/v coords myself. The purpose of this is to keep all the sides as part of a single surface; and therefore different 'textures' are packed into a single animtexture. BTW: The cuboid is just an example, I'm doing a lot more that that. |

| I can't see any other option than managing the u/v coords. They are all the same surface/entity so you can't EntityTexture each one with a different frame. |

| I'm working on something similar. What I'm doing is packing images into a texture (using an ImagePacker tool I wrote), saving the texture along with a definitions file which specifies where each image is located in the texture. Then I use functions such as: pack1=LoadSpritePack("mysprites.png") car=GetPackedSprite("porche",pack1) PositionSprite car,100,200 I convert the x/y/width/height of the image dimensions into UV coordinates then use VertexTexCoords to get the image from the texture into the quad. It's just a matter of dividing the pixel coordinates by the textures width/height to get the appropraite UV coordinates. |

| It's a shame we can't take advantage of the in-built animtexture features. An extra parameter on addtriangle or addvertex could specify which frame. The system already does most of the work as specied u/v's in the 0-1 range are corrected depending on the frame selected. |
