up4 Posted February 13, 2015 Share Posted February 13, 2015 Hi! The procedural UV section of the What's New in the H14 documentation has not been published yet. I assume that's where I'll find out how to use the new H14 UDIM features. In the meantime, has anyone been able to use it? If so how? Amongst other things regarding UDIMs in H14, I am interested in the following: How does it affect the viewport UV perspective? Does the default GLSL support UDIM at all? If so how? Are there new VEX functions to be able to use it? How to adapt the map file picker for UDIM texture file sets in for a shader? Thanks in advance, Vincent Quote Link to comment Share on other sites More sharing options...
up4 Posted February 13, 2015 Author Share Posted February 13, 2015 ps: I should add that there is a mention of a "udim" primitive attribute in the UV Layout SOP documentation. So I guess all my questions above are better put in context of that attribute and I should add: Is the inclusion of a UV Layout SOP/"udim" primitive attribute mandatory for UDIM support in H14 (if any beyond that) or can it natively use UV coordinates above 1,1 (the standard way to do it)?

eetu Posted February 13, 2015 Share Posted February 13, 2015 Not a proper answer, but check https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=28517&start=25 (via https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=37635) 1 Quote Link to comment Share on other sites More sharing options...
malexander Posted February 13, 2015 Share Posted February 13, 2015 No, the viewport does not support UDIM texturing currently. 1 Quote Link to comment Share on other sites More sharing options...
up4 Posted February 13, 2015 Author Share Posted February 13, 2015 Oh thanks eetu, Mark! You're the best as always! Sad to see that the Layout SOP is the UDIM support in H14 and that's it. Everything else still has to be user-implemented. Will stick to ol'VEX shading tricks (and maybe update them with the new string handling functions for UDIM file token replacement and support the non-standard "udim" primitive attribute as well just in case).

iks2k Posted May 10, 2015 Share Posted May 10, 2015 Great news! In latest build 14.0.328 in "Texture VOP" node added support of UDIM. You need to check "UDIM Filename Expansion". Than if you have UDIM textures like "pic.1001.tif" in filename need to enter "pic.%(UDIM)d.tif". Cheers. Quote Link to comment Share on other sites More sharing options...
anim Posted May 10, 2015 Share Posted May 10, 2015 and there is as well separate function to get udim based filename from uvs Wednesday, March 25, 2015 Houdini 13.0.727: There's a new VEX function, texprintf() which can perform efficient evaluation of UDIM or UVTILE style filename expansion.

up4 Posted May 11, 2015 Author Share Posted May 11, 2015 Yes! I will look into it soon! Thanks for pointing it out! V Quote Link to comment Share on other sites More sharing options...
