LaidlawFX Posted November 14, 2011 Share Posted November 14, 2011 I was going to do some deep compositing in Nuke from Houdini, but the deep read node in Nuke is looking for a DTEX file formatt. DTEX appears to be native to renderman. Does somebody know a way around this? And/or has somebody done off the shelf deep compositing, or is my only option still internal to Houdini with cops? I would like to use mantra to nuke. Quote Link to comment Share on other sites More sharing options...
Erik_JE Posted November 14, 2011 Share Posted November 14, 2011 99% sure it is not possible to do deep compositing with mantra renders in anything else thatn COPs atm. We will have to wait until SESI implements the new EXR stuff to do it in nuke. Quote Link to comment Share on other sites More sharing options...
moondeer Posted November 15, 2011 Share Posted November 15, 2011 maybe there is something in this lesson that can help. DT- 10 ways to work faster in NUKE In these NUKE tutorials, we’ll learn ten tips and tricks to work faster in NUKE, from proxies to expressions to python to render commands. Some of these tips will be obvious, like using proxies and the region of interest to speed up viewer performance. Others will be a bit more complex like building an expensive node disable-enable expression control system tied into our write nodes using Python commands. We'll also learn how most 3D applications create EXR files and ways we can increase performance by re-rendering them out of NUKE in its' preferred format. Finally we'll look at a cheap way to improve our motion blur from NUKE's 3D system using a combination of samples and vector blurs. Quote Link to comment Share on other sites More sharing options...
wigal123 Posted November 15, 2011 Share Posted November 15, 2011 Apparantly Cortex (open source) from Image Engine has a rat to dtex converter. I haven't tried it personally, but was ensured it works. Quote Link to comment Share on other sites More sharing options...
Erik_JE Posted November 15, 2011 Share Posted November 15, 2011 Yeah I read that after posting this as well I think cortex is just a lib tho that includes rat reading and dtex writing so you need to write a small app if you only wanna convert your files that read and writes. This is just guesses as I havent actually tried it myself. Quote Link to comment Share on other sites More sharing options...

theotheo Posted May 19, 2012 Share Posted May 19, 2012 In case you're interested: http://code.google.com/p/rat4nuke Contributions & fixes are welcome. Thank you! I think you'll get quite a lot of response on the nuke list if there's a compiled windows version Hint hint Good work, and thanks for making it open source.

symek Posted May 21, 2012 Share Posted May 21, 2012 Thanks guys, I hope it can be useful for you. Windows might be a problem for me though. No Windows, no compiler, no experience, no time to get any on them now, but I'm sure we could find a good soul with those first tree at least. Yes, eetu, I couldn't wait longer myself, so I made first move. 1 Quote Link to comment Share on other sites More sharing options...
eetu Posted May 21, 2012 Share Posted May 21, 2012 Windows might be a problem for me though. I took a quick look, and that might be problematic. Nuke plugins want to be compiled with vc8 (vs2005) and Houdini plugins with vc9 (vs2008). Dunno if there's a way around that. Quote Link to comment Share on other sites More sharing options...
theotheo Posted May 21, 2012 Share Posted May 21, 2012 (edited) edit; never mind , got it working now on linux, f12 h12.0.606 n6.3v5. Thanks SYmek! Edited May 21, 2012 by theotheo Quote Link to comment Share on other sites More sharing options...

Dunno if there's a way around that. Hmm, that means we (you?) could try to compile against H11. It might cause an issue with available licenses, but at least it could work for someone on Windows.

With some blind poking I got it to build with H12, but in Nuke the ratReader.dll raises a Runtime Error! R6034 An application has made an attempt to load the C runtime library incorrectly. which sounds like it could be a msvcrt80.dll vs msvcrt90.dll thing.

eetu Posted May 22, 2012 Share Posted May 22, 2012 Hmm, that means we (you?) could try to compile against H11. You were right, of course. 11.1.264 seems to be the last win64 vc8 build available on the download page, and it works with that. rat->getWorldtoNDC() and rat->getCameraToNDC() seem to be missing from 11.1 so I just commented them out. Also, the 11.1 libUT.dll, libPXL.dll and libIMG.dll have to be on $PATH. So, for the adventurous soul, here's a win64 build. Quote Link to comment Share on other sites More sharing options...

michaelw Posted May 24, 2012 Share Posted May 24, 2012 Hi SYmek, I compiled it with no error messages, but when I try to open the .rat file in Nuke I got the error message below: Read error: libHoudiniUT.so: cannot open shared object file:No such file or directory Nuke6.3v2 Houdini 12.0.581/Houdini 12.0.634 Quote Link to comment Share on other sites More sharing options...
eetu Posted May 24, 2012 Share Posted May 24, 2012 I compiled it with no error messages, but when I try to open the .rat file in Nuke I got the error message below: Read error: libHoudiniUT.so: cannot open shared object file:No such file or directory Did you run the houdini_setup script in houdini install dir?

mikew Posted May 24, 2012 Share Posted May 24, 2012 Did you run the houdini_setup script in houdini install dir? Hi eetu, yes I ran the houdini_setup script already and Houdini environment is initialized. Append to or export $LD_LIBRARY_PATH with Houdini's dso libraries HI SYmek, I already set this variable but don't know where I did wrong Thanks anyway.
