OK. I see. I'll mess around with the values again to see what other results I might get. Is there a good site or docs I can get for programming my own shader. Like to the very basics explaining the matrix/vector. I've attempted to make my one, but all I get is a black screen. I tried multiplying my output values too, just to get a gray or white screen, but had no luck. lol I have some programming knowledge, but I'm a bit clueless to how I'm effecting the matrix/vector let alone what exactly a matrix or vector is on a shader. I'm assuming the matrix is a grid & the vector is the section of the matrix. Or I'm a total noob & I'm way off on my assumption. =P
