Hi!

I don't usually type in scale values directly. I plug a math node into the scale values and use the math node to compute the 1/X where X is how many times I want the tile to repeat. Not only does this avoid me doing the math, it also makes it so when I want to change X, I only have to do it once.

This is particularly helpful when you have to coordinate the scales of two or more texture maps. For example, here I have a diffuse color map and a bump map. They need to be at the same scale all the time.

I use a Math:Divide node to enter the repetition factor. The value you want goes in Value_2. In the render, I showed two walls, one at X=4 and one at X=10. It's very easy to change this way and also to get precise number of copies, if that's what you need.

Note: When you use seamless repeating tiles on clothing (for example, a woven knit fabric pattern) it really doesn't matter whether or not you repeat it an integer number of times. The "edges" of such UV mapped items are not the edges of the image anyway. You'll get seams no matter what, because the cloth item is "cut" from the texture and wrapped around in quite arbitrary places.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
