Hey everyone. I'm wondering if there is anyway to offset a texture using the UV cords of an object? I'm currently working on my map engine which contructs a memblock mesh from my map array and what i thought i could do was adjust the UV points for a given spot on the map to texture that spot with a section of the larger texture assigned to the object. So say i have a texture that can be divided into 4x4 squares then from 0.0-0.25 U and 0.0-0.25 V would be the top left square and so on, but i have found it doesnt work this way or i'm doing it completly wrong. I'm asuming this can be done since DB's matrix commands work very similar to what i'm trying to do. Anyone have any ideas about this? and sorry if this has been answered elsewhere allready, i've been searching the fourms with every combination of phrases i could think of trying to find an answer to this.
