Short description of error
Generated noise texture is not infinite.
I wanted to have very fine noise in normal maps for this 32 meters wide panel. Can't be.
If there is lack of float numbers available it should do some trick of, for example, mirroring everything around, or simply looping back-to-back.
Exact steps for others to reproduce the error
Just use very big scale for noise generated texture. I expect other generated textures to work same way.
Voronoi actually goes good. Noise texture on the attached .blend was cutting black on 5000. Voronoi was good on crazy value of 200^70.
