Thanks Oscar, I am about to start rewriting them all for Houdini 15 (many many things have changed for the better and would be silly to do a plain conversion, really the new features need to be put forward)
You will have to be patient, will take me a bit as you can imagine. jb > On 11 Jan 2016, at 14:28, Oscar Juarez <tridi.animei...@gmail.com> wrote: > > Hey, I'm not Jordi, but the guides can be found on the sidefx site: > > https://www.sidefx.com/index.php?option=com_content&task=view&id=2711&Itemid=418 > > <https://www.sidefx.com/index.php?option=com_content&task=view&id=2711&Itemid=418> > > Cheers > Oscar > > On Mon, Jan 11, 2016 at 3:26 PM, Eric Turman <i.anima...@gmail.com > <mailto:i.anima...@gmail.com>> wrote: > Hi Jordi, > > Did you ever assemble your Houdini migration notes into a PDF or an ebook? > > Cheers, > -=Eric > > > On Mon, Jan 4, 2016 at 6:52 AM, Gerbrand Nel <nagv...@gmail.com > <mailto:nagv...@gmail.com>> wrote: > Yeah Mantra has this ability to make the same looking render, take 4 min or 2 > hours, depending on your settings. > But for transparent stuff.. stay away!!! its worse than Arnold with internal > reflections. > Really can't stress enough how important blender has become for rendering in > my pipeline. > I've tested cycles against redshift, and octane, and in my tests, cycles came > out top.. plus its free!! > It's a real pain to learn yet another piece of software, especially blender, > but I don't think we can afford to ignore it any more. > If someone put a gun against my head and asked me to choose between blender > and maya as the only tool for the rest of my life, I would probably go with > blender. > At least its not #mylife's future looks bright bullshit. > If mantra can get gpu rendering for those smaller but annoying jobs, that end > up paying most of my bills, life would be sweet, Until then its a mix between > houdini and blender for me :) > > > > > On 04/01/2016 12:23, Tim Leydecker wrote: > Regarding rendering in Houdini. > > Currently, in H15 (15.0303) I´m finding UDIM support a bit limited, f.e. for > all those cases where one > would want to do adjustment stuff to a texture put inside a Cop2net and then > pointing to that in a map slot. > > op:obj/cop2net/OUT > > The limitiation is that the file import available inside a cop2net dosn´t > provide UDIM extension resolving, > the workaround would be to do the adjustments to the UDIMS as if it was a > sequence (e.g. 1001, 1002, etc) > and then write the results out to file and link those as maps instead. > > That´s an extra step that could be seen desireable anyway, depending on where > the hand-off line for assets is > drawn between people/pipeline but still, I would prefer to be able to keep > the adjustments live and quickly > accessible directly from a map input slot, understood at a glance.
