notintricate Posted April 30, 2016 Share Posted April 30, 2016 (edited) Hey, I was trying to render into deep exr and faced such issue: I have simple shader with opacity falling off to object's edges. Unfortunately my deep outputs suffer on low pixel sampling rates loosing samples, however simple color exr does not. So I wonder why deep samples are lost and how to make them to be present on low sampling rates? Appreciate your help! *Dcm compression is set to 0 Here are simple examples of what I get: pixel samples 3x3 pixel samples 7x7 shader Edited May 1, 2016 by notintricate Quote Link to comment Share on other sites More sharing options...
Jason Posted April 30, 2016 Share Posted April 30, 2016 Which version of Houdini are you using? I've seen a few fixes for deep's go by in recent weeks, so perhaps it's a bug. https://www.sidefx.com/index.php?option=com_journal&Itemid=213&page=index&journal=default&view=FULL&logfile=ALL&icon=ALL&version=ALL&buildstart=&buildend=&perpage=20&search=deep&find=Find 1 Quote Link to comment Share on other sites More sharing options...

I'm using 416 build, and according to journal it seems that there weren't any fixes related to deep since that build. (However I will try the latest daily build to be sure) Should I post this one to the SideFx forum? I don't know if it's expected behaviour or some kind of a bug to be reported.

notintricate Posted May 10, 2016 Author Share Posted May 10, 2016 (edited) I submitted this as a bug to SESI and was suggested to use a workaround: turn off stochastic transparency to fix the problem with lost deep samples. Here's SESI's reply: Quote There is currently a limitation with stochastic transparency when writing 'Ce' with DCM outputs. We currently skip the sample compositing step, which results in the holes you are seeing.We are going to promote this question to a bug and address a fix for this, if possible.
