Why RMan rendering texture Y-direction is oposite to viewport? When texture in viewport displays correctly, in rendering is upside down…

is it something with a tiling/pixel order within tiffs? How to change it? Maybe there is some switch in txmake? Now I must make two versions of one texture: for OGL and for RMan.


thanks.

Renderman reads y reverse from mantra and houdini openGL.

This is a common issue for users of prman to deal with. You will have to flip your maps in Y before txmake. Some users leave the tiffs correct for Houdini then flip in Y when converted with txmake.

I don't think Houdini has written out tiffs the other way for a while now. Are you using an old version?

well, that what I am doing, I got two ver. of tex, for OpenGL and for txmake. I've just was wonderd if this is common issue or it's just my ignorance. I even don't comply…, after hard work in shake I understand that for some apps. tile ordering is a matter of life or dead . Thanks.

edward: I use sixth and convert textures from large jepegs to tiffs and… rats Maybe there is some global variable or switch to change tile ordering in H…


thanks for reply,
Symek.

By “I use sixth”, you mean Houdini 6.0?
