Ya most of the freebies are 100% math no textures.

Well the size of the tile depends on what you are gonna tile it on and how many times it will be tiled. I don't much care for the tile value since it is a decimal number not a multiplier. For tile to work best they should be tiled and even amount, 2x2, 3x3, 4x4, 5x5, 6x6, etc. Well as a decimal this requires a bit of math. 2x2 = .5, 3x3 = .333, 4x4 = .25, 5x5 = .2, 6x6 = .166, 7x7 = 142, 8x8 = .125, 9x9 = .111 and 10x10 = .1 (this is the value for the U&V sizes) the main thing to remember is to not over size the tile. If the tile is 1000x1000 and you tile it 6 times the equivalent texture is 8000x8000 if this is being used to detail say a sweater on a full body render that is 2000 pixels high you will never see the detail in the texture since the program has to down sample the texture by about a factor of 8 (since the sweater area in the final render is likely 1000 pixels or less). If you have a matching bump map you likely will not even see the effect of the map. Now for the same render done at 10,000 pixels high, the tile settings would be about right.

As a rule I make 2 tiles, one small 256x256 and one large 800x800. If you find the res is a bit low increase the number of times it is tiled as this will increase the resolution.

Hope that helps some :-)

And you are welcome for all the freebies :-)
