Dear Forumers, I am trying to render a reflection of my scene in a pane of glass to comp in Nuke. What I need is an alpha channel that is composed of the objects in the reflection NOT the pane of glass itself. How can I achieve this? I'm guessing also that a cryptomatte which contained the objects IN the reflection would also be just as helpful but I don't know how to get that either? Thanks in advance, Nick PS: I am using Karma PPS: Ideally I would like to do this in the OUT context, NOT Solaris

Hi everyone, I'm newbie to Houdini and Redshift... I need your help! I failed to render Cryptomatte with correct object ID, and want to re-render only Cryptomatte without rendering main images to save time. Is it possible or is there any way to skip rendering main images? I just don't want to waste time to render the same images again..... I appreciate your help! JK -
Hi, I'm trying to setup and use stylesheets with redshift and not having much luck. The main thing I'm trying to do is override the redshift Object ID so that I can have unique IDs appear in the cryptomatte per point. All I've done is a voronoi shatter, then assembled them with packing on. I haven't had any luck past this point. If someone can point me in the right direction would be helpful or propose an alternative solution. The only other thing I can find or think of is assigning per point materials but this is out of the question since there will be 2000+ points. The post here seems to mean that this is possible: I've also gone over the Mantra way of doing this here several times without any progress: http://www.sidefx.com/docs/houdini/shade/stylesheets.html

Hey, I need to render with objectsID AOV, with Arnold, and I'm failing miserably :/ In the AOVs liste, there's an ID aov, but can't make it work. So I looked into Cryptomatte since I'm using ALshaders. I can't find info about how to use it, just a tutorial for maya on anderslanglands.com, where it seems simple (just enable crypto_object and crypto_material). But there's no such things in Houdini :/ All I can see about cryptomatte is in the shader nodes, there's an AOV tab with confusing things... Can you help ?
