men )
trying to make nice ribbed metal surface in cycles
have map
but render gives me unpleasant noise
using displacement also gives not nice result
missed something?
thx
p.s. sizes are very small - centimeters… maybe this is problem
Yep. Missed. Missed the fact that jpg is the worst image format due to compress/uncompress losses of information/distortions introduced.
For the real displacement (cons - heavy on vertices objects needed) best option is full 32-bit scale images - OpenEXR as a first candidate.
Missed that Blender can generate such stripes in full glory if you use Wave texture.

okay
wave tex is a nice idea )
but how to map it correctly on cylinder?
for UV map & unwrapping its simple
