wizuby Posted April 20, 2006 Share Posted April 20, 2006 I am wondering if there is anyone out there that knows of a good tutorial covering multipass rendering in vray, but more specifically how to composite multiple render layers in PSD. I understand the concept but not the technique. I know it is a valuable tool...and wish I knew how to use it better. Anyone found any good info or tutorials?

Christopher Nichols Posted April 20, 2006 Share Posted April 20, 2006 Wrote this a while ago... it is for comping packages. PSD is somewhat limiting and does not do basic comping really well. http://www.chaosgroup.com/forum/phpBB2/viewtopic.php?t=13818 Link to comment Share on other sites More sharing options...
RobMc Posted April 20, 2006 Share Posted April 20, 2006 Wow, thanks Christopher! Will have to give this a try - looks like it could take my image adjustment to a new level! (if I can get my head around linear workspace etc...) . Will have to read throbs post again..... and again and again and... Link to comment Share on other sites More sharing options...
michael2983 Posted September 6, 2007 Share Posted September 6, 2007 Hello, I am new to vray multi-pass rendering. I am using 1.5 RC3 (there is no more G Buffer option, only Frame Buffer). How can I render out separate reflection, specular and diffuse passes in Vray? I am having a difficult time figuring this out, any help would be a huge huge help. thanks in advance.

Thablanch Posted September 7, 2007 Share Posted September 7, 2007 The G-buffer no longer exists, now you have to go in the: Render > Render Elements rollout and select the passes that you want to be saved. Link to comment Share on other sites More sharing options...
michael2983 Posted September 7, 2007 Share Posted September 7, 2007 Thank you Thablanch! So simple, can't believe I didnt think of that .. I think all the G-buffer documentation threw me off ; ) Do you know any good resources for compositing tutorials? ie, which render elements are best to blend to obtain final render quality? thnx.

devres Posted November 21, 2007 Share Posted November 21, 2007 Darn, it doesn't link to anything now that they changed the forum over there. Chris, any chance of "re-writing" that one. Link to comment Share on other sites More sharing options...

Sketchrender Posted February 4, 2008 Share Posted February 4, 2008 Will it actually save the passes for you into a file? I don't have combustion, and want to have prepass options, and don't want the hassel of saving each element seperatly myself. By the way getting into the chaos group form is a nightmare. I log on and now i can't get into the forum. What gives. why so hard to get in. phil Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted February 4, 2008 Share Posted February 4, 2008 I have composited images recently for the first time. Like anything, there are pros and cons. I highly recomend readng this thread on the Chaos forum. http://www.chaosgroup.com/forums/vbulletin/showthread.php?t=38104 You can write EXR out of the Vray Frame buffer, the area where you typically write out Vray image files. The EXR's saved out of this area will have all of Vray's render channels that you specified as being active saved into one file. However, to take full advantage of the channels you really need a higher end EXR plug-in like ProEXR. Chaos Forum user Shimakaze wrote a nice PhotoShop action script that takes the EXR opened with ProEXR, and arranges and sets the proper blending methopds to recomposit the image. I was able to get an image very close to the original render, but it was alittle off. You will need to manual adjust the intesity of the reflection and such. All in all, it is a good introfuction to compositing images in photoshop. I think compositing is going to be the next big movement in Arch Viz. Similar to LWF and floating point of a the last couple of years. He also covers basic compositing elements that are universal for almost any render engine.

Sketchrender Posted February 5, 2008 Share Posted February 5, 2008 Thanks for the response. Can you tell me. Is there a way of getting max to save out all the passes in to one file automatically. I know there is for combustion. Is there a way of doing it for photoshop? phil Link to comment Share on other sites More sharing options...
Chad Warner Posted February 5, 2008 Share Posted February 5, 2008 Cebas make a plugin called "Psdmanager" that will do this. Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted February 5, 2008 Share Posted February 5, 2008 also, saving a EXR out of the V-Ray raw image file roll out will save an EXR with all of the specified Render Elements in the EXR file, but you need an advanced plug-in like ProEXR to properly extract the channels from the EXR. i haven't messed with RPF's or RPA's in years, so i can't comment on those. my guess is you are going to need to buy either PSDmanager or ProEXR to accomplish this properly.
