theflu Posted April 1, 2013 Share Posted April 1, 2013 (edited) hey! is there an easy way, maybe a expression or sth, that lets the mantra surface material read uv tile (udim) textures instead of just one image per channel? (instead of going to vop and set them up offsetted manually) thanks in advance! ulf Edited April 1, 2013 by theflu Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted April 1, 2013 Share Posted April 1, 2013 I don't know of a standard way to do this in Houdini but since there's logic to the organization of the UDIM textures you could setup an OTL to handle this (take the path of one into Python and use regular expressions to find all the tiles). Maybe someone else knows of more intuitive way than building an OTL from scratch though. Quote Link to comment Share on other sites More sharing options...
theflu Posted April 2, 2013 Author Share Posted April 2, 2013 (edited) thx luke. (doing python/otl is way over my non math brain ) maybe someone else will have a nice solution to share. Edited April 2, 2013 by theflu Quote Link to comment Share on other sites More sharing options...
rdg Posted April 2, 2013 Share Posted April 2, 2013 not sure if this is what you're asking, but this page seems to have the math to convert udim into uv: http://bneall.blogspot.co.nz/p/udim-guide.html Quote Link to comment Share on other sites More sharing options...
theflu Posted April 2, 2013 Author Share Posted April 2, 2013 (edited) hey georg, thx, i am aware of that. i know how to set them up.. i just look if there is an easier way to feed a channel of a mantra surface with those, than going in to vop and setting up / offsetting them by hand. something that feeds uvtiles, like one loaded image, to a channel ..

sanostol Posted April 2, 2013 Share Posted April 2, 2013 maybe a texture otl with a editable network would be fine for You , and a button that triggers a python script that fills the editable network with a correct vopsetup Quote Link to comment Share on other sites More sharing options...
theflu Posted April 2, 2013 Author Share Posted April 2, 2013 hey martin thx... jes, sounds so. i just thought, as its pretty common in usage these days, sth like that would be already available, somehow, somwhere. so long, i gonna set them up by hand Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted April 2, 2013 Share Posted April 2, 2013 The theory behind UDIM textures seems reasonable but I had to lookup what it was because I had never heard of it before. If you're not familiar with Python this would be a good opportunity to give it a shot. Quote Link to comment Share on other sites More sharing options...
petz Posted April 7, 2013 Share Posted April 7, 2013 no need for python - could be done fairly easy with an expression and material overrides. file is attached! hth. petz udim_textures.rar Quote Link to comment Share on other sites More sharing options...
