- So I spent some time fumbling around in MaterialX and Karma, so you don't need to and here's what you MUST know if you are going to use MaterialX and Karma.
By the end of the video, you will understand when to use materialx shaders and when to go back to our beloved vex shaders.

I think there is not enough video-material on karma - can I study mantra before karma? How manrta is comparable to karma?
If I were learning rendering in Houdini now, I would focus on Karma.
Good video and well explained. I find that Karma in ROPS looks better (at least to me) then Mantra but it is just as slow or insignificantly faster. I will have to test it in Solaris because from what I understand that is where all the benefits come from.
In most cases Karma CPU is about 40-60% faster at rendering then Mantra for me.
The 2 renderers will never produce the same image with the same lights and shaders.
So it is quite subjective which render looks better. Whichever renderer the lights/shaders were initially look-deved in will probably look the best.
Using Karma via Solaris is the recommended way in the long run.
Very nice one thanks Nelson! Subscribed
You're welcome!
Is it possible to adjust the colors from a texture map in materialX?
I see a saturation and contrast node but not a node to adjust the colors like colorcorrections node Hue Shift in Mantra.
I haven't played around too much with that yet. But there's a MaterialX HSV adjust node. www.sidefx.com/docs/houdini/nodes/vop/mtlxhsvadjust.html
That is great. Good job.
Thanks Faddy!
:)
Very useful tutorial👍 Can we render Material X in Arnold houdini ?
Yes, arnold supports materialx.
Which camera did you used for record this video? Looks so cinematic!
Thanks. It was a point and shoot Sony EV1.
Insanely well explained. Thanks man
Glad you liked it!
check the changelog for latest stuff, alot of big fixes have been done to Solaris, mtlx and karma since build 383. I am talking a serious lots of updates.
Yes, looking forward to updates and bug fixes for Karma.
- we have 12 standards, it is too much....
- Let's invent single united standard!
...now we have 13 standards
Such is technology in general. But from time to time things start to converge. USD and materialx does seem to have the support and features that is getting many industry players and artists onboard.
