hello,
I'm probably gonna loose my minds today... no matter what settings or tweaks i mess with I can't get rid of these reapeating patterns in my texture
the following image shows perfectly what I'm trying to explain....It's a leather texture in maya...
So, it there something I have overlooked? Or could it be that... dunno, at least this texture can't achieve true randomness in infinite space...
PLEASE! help me out
...kind regards, everybody!

You can use automatic mapping for that and also see if the texture have many more repetitions that it support

Also you can use the (dimmed) alpha of another map plugged in the density of your texture. Cloud, Brownian or Fractal are good for that purpose.

thank you kindly...
first of all, vancliff, I have to shamefully admit that I have no idea about what you're saying...automatic, is that by any chance the 'local' option in the 3d texture?

Exo7-ok...here's a screengrab...You can see in this poor man's test I'm still failing at this...
I've linked a scene so If you have 10min to spare maybe you can have a go at it...

Er... yes, sorry, just saw your post. I'm giving it a try, I hope I'll do as well as I said :arteest:

omg, no wonder why I stopped using these textures years ago :eek:
Would you forgive my foolishness if I offer you this shader ? It won't repeat ever I promise :blush: by tweaking precisely the forementionned alphas, you'll get a whole range of natural looking surface, from rock to muddy walls... works also with mental ray, and loves displacement...
