Thanks for the answer!!!Can you link to me the manual url please?
I'm not understand why I must do that (rescale) because if I change the kernel window and the step I get different value from 300 (but all over 255). 

If I do this rescale and I compare the result with the ENVI tool or the ArcMap tool, I get the same results or this rescale will change the result?

Thanks in advance for the answer!

Like this:

r.rescale input=input output=output to=0,255

r.texture ...

I have improved the manual now to better explain this issue.
