Could you give more information about the image you posted? Is it generated with a set of blended procedurals and what are they? How did you set the parameters?

Hi seghier,

Is this created with the new Brick procedural?

In that case, the bricks Sample Size parameter allows you to indicate the size of the random patch taken on each brick, so the lower that value, the smaller piece of texture will be taken, thus the less repetition you will see.

thanks Tom and Dario
no i didn't create this texture i just would show you the problem of repetition (but i will try to create one)
i create other texture : i tried to reduce width and height 0.1x0.1 of brick and i decrease repeat 0.5x0.5 and i get one texture with 10 brick in each direction but always i see repetition
in this image the same thing

procedural or not, texture is a texture.
This depends on the size of the matrix ...

The advantage of procedural texture is having tileable texture.

yes you are right but there exist solution like multitexture
procedural texture can do that but we must decrease the mapping ; if maxwell team develop it for big texturing

other question
i create material with procedural texture brick
in the brick parameters i choose procedural texture but; i can't modify the parameters of the new one and i must choose any other texture to active the new procedural texture

i have question about blending factor ; how we can use it to blend different procedural textures?

If you don't want visible repeat, you need to design your procedural in higher matrix than 4 x 4. Procedurals are not repeating withing their own. It's the tile value tiling it. So, this answers your first question I guess... ;)
Blending Factor is working up to down in the procedural stack. Setting the above procedural's blend to 50 will set its normal-blended contribution to 50 percent against the rest of the stack in order.

thank you Tom :) ; yes you are right
i try to create tiles with dirt effect ; procedural texture give nice result ; and i will try using blending factor
