Another Bug???

Has anyone else noticed this anomaly with the way ZBrush handles UV Cylindrical mapping? All of the other mapping options function as expected. However, when UV Cylindrical mapping is applied even to a simple sphere, something weird happens along the longitudinal seam.

Take a look at the model with the B&W texture applied with cylindrical mapping.

Fiirst, notice the oddness where the edges of the texture come together - but also look close and you’ll see a series of thin vertical lines there.

Whatever the problem might be, it affects how tiling works under UV cylindrical mapping. Take a look at all of the other mapping compared to the last column - the same parameters result in a problem for the vertical repeat.

I would be curious if anyone can reproduce this problem… and if Aurick or Pixolator have any explanation as to why this might be happening?

Thanks for looking,

Sven

[addendum: I think I know now what causes the problem, though I don’t think there is any workaround in ZBrush. :frowning: ]

…vicious :lol:
A “cylinder” projection on a “sphere” :rolleyes:
Have good research on your problem :cool:

Frenchy,

Something maybe gets lost in translation, I don’t quite understand what you are saying, but thanks for your help anyway… :wink:

I’m gonna try it in a bit and see if i get the same results.

Does the problem remain if you use the fix seam button in tools>texture menu? or try the offset?

ok shut up aminuts and go try it yourself…:smiley:

same thing…here are some pics

I had tried it with same results so…

pic1…i took the sphere into uvmapper and mapped in x, y, and z however my stupid self forgot to change the orientation when I remapped it in z. but you can see some problems here.

Pic2…i took the uvm x sphere and tested some textures then did a uv check on it…then remapped in z as uvc and uvchecked it…yikes!!!

Pic3…this one I mapped all in z…the xyz mark position poles are facing in preview mode, stored or restored, redrew, remapped in zb uvc then uv checked. double yikes!!

something is definitely whacky!!

Thanks for the double-check Ami,

Have a look in your regular email box for something I just sent to you to try out. Let me know that you got it.
