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.

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.

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.

Apparantly Cortex (open source) from Image Engine has a rat to dtex converter. I haven't tried it personally, but was ensured it works.

[Erik_JE]

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.

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]

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.

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.

edit; never mind , got it working now on linux, f12 h12.0.606 n6.3v5.

Thanks SYmek!
