The colors of the warp (U direction) and weft (V direction) threads of the cloth.

The color of the area between the warp and weft threads. The threads’ colors blend into the Gap Color at their edges, so a lighter Gap Color tends to simulate a cloth with softer, more translucent threads.

The width of the warp and weft threads. If the thread width is 1, then the threads will fully touch with no gap between them. If the thread width is 0, the thread will disappear. (You can randomize thread width by setting the Width Spread parameter.) The valid/slider range is 0 to 1. The default value is 0.75.

Controls the waviness of the warp and weft threads to create special weave effects such as herringbone. The slider range is 0 to 0.5. The default value is 0.

Smears the texture randomly in the U and V directions. Adjust the Randomness value to create natural-looking cloth with irregular threads, or to prevent aliasing and moiré patterns on very fine cloth textures. The valid range is 0 to infinity. The slider range is 0 to 1. The default value is 0.

Randomizes the width of each thread along its length by subtracting a random amount (between 0 and the Width Spread value) from the U Thread Width and V Thread Width values. For example, if the thread widths are 1 and the Width Spread value is 0.75, the actual thread widths with vary between 0.25 and 1. If the Width Spread value is greater than or equal to the Thread Width value, then some threads will disappear entirely at certain points along their length. The valid/slider range is 0 to 1. The default value is 0.

Randomizes the brightness of each thread along its length by subtracting a random amount (between 0 and the Bright. Spread value) from U Thread Color and V Thread Color (similar to Width Spread). The valid/slider range is 0 to 1. The default value is 0.
