Intro to Karma Materials for Beginners in Houdini

[@andersutterstrom6089]

I think I cracked the code thanks to this video. Took your ideas and added some textures. Very quick results! Thank You and looking forward to your procedural video.

[@bubblepins]

Sounds awesome! I'm happy my video was helpful to someone!

[@Tallmnn]

Great content! please don't stop posting :3

[@bubblepins]

I've been doing some live streams! But I'll have a new long form video soon, I'm still working on it.

[@Learn_9654]

The content is good and the voice sounds wonderful

[@bubblepins]

THanks so much for the lovely comment!

[@mohamedazab3586]

Thanks, I need to know how to add material xpu for flip ocean pyro explosion particles rbd and vellum

[@bubblepins]

There's a bunch of open source materialX by AMD. In Solaris, drop down a material linker node and on the parameters panel, you'll see some weird graph thing, in the middle top, there's a gear box button to add a library and it'll ask you where to save the library, then you can drop in the materials into your project. They have a water material. As for Pyro explosion, just reuse the mantra materials. You maybe have to break all the links if you created the pyro sim using the shelf tool, which also automatically creates the mantra pyro materials for you. If you copy and paste that into karma it'll work, but sometimes they have links linking into places in SOPS, you'll have to break those links before using it in karma.

[@Razafx]

Very useful tutorial! Could you please create a tutorial on rendering flip and pyro simulations with Karma XPU? I also explored the AMD Mtlx library but couldn't find any water materials there, thanks.

[@bubblepins]

I'll try to fit it into the next video!

[@Razafx]

@@bubblepins That will be very helpful.

[@TheBaldMansWay]

How to bake karma materials to texture maps from one model to another (high-poly to low-poly)?

[@bubblepins]

I hadn't thought of that! i'll look into it

[@cgvapour]

Is there an easy way to import shader and texture from substance painter? Do I just use materialX?

[@bubblepins]

I have a Karma Material Generator HDA that I'm releasing to my Perk Members this week, that's shown in the video @19:07 but if you want something out of the box inside Houdini, I know there's a substance node on the SOPS context, but it's meant for Substance Designer materials (not Painter). Other than that, that's all I got. Hope that helps!

[@chamsbenzina]

am facing problem with karma when importing 50 fps video or custom fps and render using carma on tthe video and track 50fps th evideo fps do not lmatch at all jiggly but when in the same project in houdini engine i use other render plugin it fits perfectly on the video frame aftrer rendered , like there is something wrong with kkarma fps even tho i shows that it would render on 50 fps it doesn't fit the 50 fps video3.

[@bubblepins]

Are you importing a video on an image plane? Or like a baked animation? The viewport renders really slowly in realtime, you need to create a flipbook for accurate fps viewing. I'm not sure if this is what ur having trouble with, but I hope this helps!

[@chamsbenzina]

@@bubblepins the problem is in flip book in the scene view the movement is perfect too .. the only problem is once rendered

[@bubblepins]

@@chamsbenzina what u get in the flipbook should be the same as to what u get when rendered. Double check the ROP USD Render node when rendering in Karma or double check the other render settings node that may affect the render quality.

[@chamsbenzina]

@@bubblepins yup i know and double checked and same stuff same scene when i use arnold everything is good but in karma just off the render in frame rate they is minor missmatch which make it unusable ..

[@bubblepins]

@@chamsbenzina The thing is I don't think Karma changes the time, it just renders out whatever is in the frame for each frame. The only way that I can think of that would affect the time or playback is some sort of animation playing in ur scene that has configured timing like a time shift node or time warp node or even the time parameter in a solver. This is a very unusual bug. Sorry I'm not sure what other parameters I can think of.

[@jamesc1589]

Amazing video! Was wondering if anyone knew where to input Ambient Occlusion. For now I've been using the MtlX AO node and mixing it into the base color. It "works" but is almost definitely wrong, any ideas?

[@bubblepins]

I'm assuming u mean AO texture map? I'm sorry if I misunderstood! Technically Karma doesn't need AO, because it has ray tracing so we don't need fake AO's. U can get ray traced AO's calculated from the Karma engine that will dynamically update, even better than AO texture maps that won't update!

[@jamesc1589]

@@bubblepins Exactly what I meant! And even better I don't have to worry about it. Thanks for the quick reply, and for your channel as a whole. Doing Gods work for the Houdini community!

[@bubblepins]

@@jamesc1589 Ur words r too kind!

[@salvio2776]

Thank you, imma try this to make an better coffee or juice material, its so easy in redshift but its hard in karma

[@bubblepins]

ohh I think one of those AMD material link has coffee or juice, but too bad you can't customize those materials. You have to take it as it is, so I get what you're saying.

[@TomCushwa]

I am a member of bublepins but I can't get the password for file for this tutorial.

[@bubblepins]

Hi Tom, you've been a member forever, thanks for all the support! Can you access the youtube post: kzbin.info/door/gSL2gPQragMHtVh3f2YUQAcommunity?lb=Ugkx0QEiagj5p72DlTv87n2KdbCAco0lrLvy Does this give you an error? On a total different topic, the Karma HDA Material Generator will be released in a few more days, I just gotta clean up a few things and record a demo video on how to use it. That way you don't have to recreate the tedious PBR texture setup process. I found it to be very useful, I hope everyone will find the HDA useful too.

[@EmreAy-v1c]

Great video, excellent content. Supporting comment for the algorithm!

[@bubblepins]

Thanks for the comment! It does help!

[@teccc42]

Thank you! Very helpful video.

[@bubblepins]

Thanks for the comment! I hope to create more Karma material videos, going to dive into procedural materials soon!

[@TomCushwa]

Thanks.. Very illuminating!

[@bubblepins]

Thanks so much! I super happy you like the newish format that I'm trying out. I'm trying to improve on the quality of the content and perk benefits, but it does take a little longer to produce. But I do think I'm getting faster as I'm getting use to the new workflow. If you have any feedback I would love to hear from you!

[@AshR6-y3e]

Can you plz make a tutorial video on material x room node and love your content ❤❤❤

[@bubblepins]

room node! I thought it was a typo when I first read your comment, I had google it and wow there really is a room node! Is it that parallax thing I saw in SideFX's keynotes?

[@sakibkhondaker]

kzbin.infowUeRtuZM-hw?si=DaTbkmvlHFas62Us

[@sakibkhondaker]

I have tried it. Works well.

[@bubblepins]

@@sakibkhondaker It sounds very interesting! It reminds me of that ChipWalter's Blender's addon.

[@sakibkhondaker]

Yes similar thing. I also tried it with my Procedural Building. It is pretty flexible. But my concern is how can it be exported to Unreal with the room textures attached. @@bubblepins

[@brokenfix]

Is the Karma Material Generator HDA compatible with Houdini 20.5?

[@bubblepins]

That's a good question! I did a quick test, it looks like it's working! Remember to download the latest version 6.0 it has a few bug fixes a bit of improvement. It now creates the LOPNET for u, so you don't have to worry about overwriting ur previous setup.

[@TroubleShotVFX]

"The learning curve is minimal because it's like Houdini..." oh no...

[@serialvision]

great video! thansk fro sharing

[@bubblepins]

Thanks! This video was fun to work on!

[@nonenone2748]

Houdini is famous for its deduralism, and Karma is as procedural as polygonal modeling?

[@bubblepins]

Karma is the built-in render engine of Houdini, Houdini's famous for proceduralism.

[@nonenone2748]

@@bubblepins yes - a know but is Karma procedural?

[@bubblepins]

@@nonenone2748 yeah it's as procedural as it gets!

[@Heartless0RD]

niceeeeee

[@bubblepins]

Thanks!

[@nicksushkevich]

Can we fucking have something beyond "for beginners"? How about advanced Karma setups or something? Tired of 100500 "for beginners" videos.. Sorry.

[@bubblepins]

I'm slowly building towards a little more complex video, I usually like to start from a simpler video so I don't leave any of my viewers behind. I use to number them concepts 1, 2, 3,4... for clarity, but youtube doesn't like that. Please be patient, the next video may be more interesting to you, it will involve a bit of procedural materials in karma.

[@reasonsreasonably]

@@bubblepins If I were you, I would have ignored that guy demanding something not for beginners, for free. I was about to tear him a new one, but I guess he is ESL and doesn't know that his words are out of place and disrespectful. Thanks for your efforts. You're appreciated, and take your time and don't feel pressured. Kids these days...

[@bubblepins]

@@reasonsreasonably I thought about ignoring it. His comment was a bit mean, but I guess I tried to give him the benefit of the doubt. Thanks for your support! I appreciate all the kind words from all comments that everyone gives me, it does mean a lot to me. These videos do take a long time to produce and its your generous comments that keep me going.

[@reasonsreasonably]

@@bubblepins You must be Canadian! Keep up the great work!
