This Karma MaterialX shit in H20 kind of looks like ass don't you think? My other renderers destroy it though in quality (materialX just cannot compete at this time) but the integration into H20 and the fact that it works with each daily version of Houdini makes it strong.
For my other renderers I may be literally months behind daily version, that 3rd party Houdini ROP bridge may cause instability and I have to pay more for that renderer per year than I do for Houdini Indie alone. Does anyone else feel strongly about Karma?

the whole point of karma is adhering to a standard that will be present across every single package so that multimillion dollar studios don't waste time (TL note: time means money) on troubleshooting why material x in renderer y is giving a different result from renderer z.

you've typed a number of words in the op that you clearly don't understand. i'm assuming this is bait. that or you're genuinely not very clever.
either way, stop breathing.

What is wrong with you, dude? Are you gaslighting?
I use a renderer that has been around for literally decades. Karma just got out of beta 2 months ago.
Are you an idiot?

Yeah and? the results dont look very good. My other 2 renderers destroy it.

>can't articulate any specifics
brainlet skill issue. i actually have specific gripes with karma but you're not worth talking to.

>Specifics
Look at MaterialX Standard Surface and its horrible sss. Absolutely terrible subsurface. I use sss a lot and this is the first thing i tried. What in the hells were they thinking?
Look at Karma Material Builder. Its baby level and doesnt support new lobes, just uber shader connections. Its not even close to the freedom of MtlxLama (unsupported in karma cpu or xpu)

name six renderers that support lama

i did. I said it looks horrible and it does. Fuck off.
>name six renderers that support lama
no point. It exists, its part of material x, and its not included. You sound very pathetic.

What issues are you having with the SSS? In general the parametrization for MaterialX tends to be weird and not very artist friendly, but I've found the behavior of the subsurface to be pretty easy to dial in, and Standard Surface is generally nice to work with.
But yeah, overall there are still a lot of missing pieces for MatX.
>its part of material x
Despite the name, Lama is strictly a RenderMan thing for the time being. Think of MaterialX in Houdini as a reference implementation. Until Lama is actually rolled into the spec, it most likely won't appear in Houdini. Go ahead and look at the MaterialX spec and physically based shading nodes documents, you won't find any mention of Lama.

Materialx lama is used by ILM, the creators of materialx

Right, they released it initially, and it's now an open standard with a bunch of contributors from all over. Lama still isn't part of the spec though and as far as I'm aware no other DCCs or renderers aside from RenderMan incorporate Lama.
The long term goal is to align MaterialX and Lama so it's a proper part of the specification, but who knows when that will happen.

I avoid things that aren't 'high grade' so I don't use my GPU to render at all let alone with things that aren't ready, even if the difference is negligible. I don't touch Karma period (for now)

he'll never say because it's likely he's never used houdini.

if you want to render on CPU then use the ILM proven workflow with MaterialX Lama in Renderman

Bros I may have been wrong about this houdini karma shit....It takes a strong man to admit that he may have been wrong.
From doing monitoring tests between karma and another commercial gpu renderer, karma was using substantially lower vram. At least 60+% less.
Still, I feel like I have to stay committed to my previous toolchain for a little while longer and do a gradual change over to Karma over the next year or so and not just jump ship blindly

Damn...
Btw sss depth is set to 0 by default
Turn it up
