Hello! I know this is a long shot but I've not found an answer to this question and I know there are some brilliant programmers on this forum so I thought I'd ask. Is there a replacement for OpenDX? It used to be such a useful environment for creating node based, procedural systems and I could really use it for upcoming projects. Thanks!
paxsonsa posted a topic in General Houdini QuestionsHey all, The team at Psyop just open sourced their ID matte toolset called cryptomatte. I started working there a couple months ago. we are looking from some contributors for Mantra implementation for the project! anybody interest? https://github.com/Psyop/Cryptomatte Have look and if your interest hit up the team, we are eager to make this apart of mantra Cheers!
Hi Guys , I would be curious to know if some of you would be interested to help me work on an Open Source Mantra Shader. There are actually some very cool PBR shaders right now like those one : http://forums.odforce.net/topic/18353-pbr-all-purpose-layered-shader/?hl=danylyon http://forums.odforce.net/topic/20682-bsdf-bonanza-ggx-microfacets-disney-brdf-and-more/ http://forums.odforce.net/topic/21673-physhader/ The problem is that the first 2 are not accessible in VOP , you can't modify them yourself and thus you are not 100% free. The last one is also very cool and will help me a lot to understand VEX more in depth. But i would like to work on a modular shading tool. base on a core BSDF that you would then layer to build complex material. Most shader are more UBER shader like the V-Ray MTL / Arnold Standard / MR MIA / Mantra Shader. But i would like to have something closer from what you have in Maxwell or Octane. Where you combine BSDF. I'm quite bad in complex math, but i guess by combining some brain power here on od force we could achieve something cool. So i would have some questions before starting to work. Q1 - what would be the most powerfull environment to develop a cool mantra shader ? - Material shader builder context inside houdini - CVEX shader builder context - external compile VEX code - external compile CVEX code Q2 - what would be the most elegant organisation to keep thing easy to read / maintain ? - full VOP node organisation - full VEX code organisation - a mix of VOP and VEX with inline code Q3 - what are the requirements if we want to be able to make it work in Reyes/Raytrace/PBR ? - does CVEX shaders work in all mode ? - how to emulate the compute lighting node in CVEX ? For the moment i was thinking to start to work with those : - Material Shader Builder Context - mix of VOP for utilities and Inline Code for core shading functions - VEX I would be glad to have as much advise and pov on the subject ! Cheers E
