How to use Poly Haven textures in Houdini with Karma

There are a couple potential little snags with hooking up Poly Haven PBR textures with Karma in Houdini so this video goes over how to get it done correctly

[@sheeperson]

you can use a "Mtlx Range" between image and displacement node setting Outlow as -0.5 and Outhigh as 0.5

Brilliant video! short and doesn't overcomplicate anything. Thank you! :)

[@chinelothenigerian]

Thank you for the tutorial, simple and easy to understand.

[@jordanhwang]

thank you for talking about karma! I’ve had some of these issues before too and this helped me figure out why

[@ahmednasr93]

Thank you! This was a very good tutorial!

[@peterpejanovic2652]

Thänx a lot for this very useful tutorial!!! Helped a lot!

[@Rubicon1985]

Thanks chief - that was brilliant

[@quirtje1]

Great tutorial, I also liked the sporadic cat noises in the background

[@minafishi]

If all you're looking for is the node diagram here it is. Subbed for the straightforwardness, gonna watch the video anyway

[@axendroo2541]

really helpful brother, thanks a lot. love from bharat

[@liuhaiying6844]

nice video, thanks for your help

[@MrN0rmalPlays]

Thank you for sharing!

[@RMAFIRE]

Keep on hustling💯💯

life saver!!!

Your displacement is stretching around hard/high curvature edges. If you create a second N attribute (name it Nn or Nb or something unique), blur that and then use THAT as your displacement direction, your textures will no longer stretch around edges.

[@g8610g]

That sounds handy. Could you elaborate on how/where exactly to put that? 🙏

[@vladartiomav2473]

As always, Houdini makes simple things hard and hard things simple 😄 Nice to know we have this kind of control! Don't even know if it's even possible in other DCCs.

[@WillPreston3D]

this was great, thanks so much.
is there a way in matX or principled to set how many subidivsions it does at render time?

[@danacarvey]

Thanks for the tips! Can you please tell me how to connect up a triplanar node to avoid having to do UVs??

[@Tritoon710]

And for the Normal map I think you need to set the Signature to Vector3

[@metaturnal]

And how to use the AO texture?

[@burneracco]

Spot on matt! just a quick question, my test pig (other test geometries as well) loads up without any shader/texture inside the sopcreate node, any idea why its happening?

[@MattBell]

The shaders created in the normal sop context don't apply to the lop context with Karma by default. Thats why we have to add Material Library, and Assign Material nodes.

[@minafishi]

if anyone is having issues with getting their GPU to render in the viewport, go to perspective(?) ( next to camera button) > render settings > /Render/rendersettings, deselect viewport render. Had mine plugging away on CPU only. Open to suggestions if someone knows how to set viewport render default to XPU

[@rendered_useless2093]

Hi how would you change the color of the diffuse image for instance if you want to change hue or multiply it by another color value I find houdini very confusing with all nodes just looking for simple way like color ramp in bledner
Also i confuse about roughness because why is button for roughness blue but output on image texture is green?

[@vladartiomav2473]

For roughness you have to set your image texture to "float". It's like "non-color" option in blender. The difference is that in Houdini they bombard you with the real terms and not the abstraction ones.

[@vytasrauckis6703]

Does anyone know why my HDRI background doesn't show like in this video? All I get is the default viewport gradient background and grid.

[@westparezal]

can we use it with Unity engine?

[@artadecram_9624]

I think there is not enough video-material on karma - can I study mantra before karma? How manrta is comparable to karma?

[@BRUTOFX2040]

minute 13:32 its your cat? 😍
