Will Karma be fully integrated like Arnold in Maya or Cycles in Blender.
At now, it's very user unfriendly.

Karma is a USD based Render Engine with Hydra Viewport Integration. In other words you could Integrate Karma in every Software that supports Hydra and USD and it feels like a native Renderer. Other Render Engines will feel the same as Karma in Solaris if they Support the USD / Hydra / MaterialX Specs.
Surly some Functionality is missing in Solaris, Karma needs some more Features but i am 100% sure H20 will be a awesome Release.

When you do manipulations on points, primitives then you use VEX or VOP.
When you want to import data,special UI, tooling then you use python.

If you want to master houdini you will learn anyway both. For the start you need to understand the basic's and use some expressions that is the hardest part as a new user.


My brother started 2 months ago to use houdini as a indie artist. 1 month was a hard time for him, 2 month he understands the houdini way and likes it more and more.
He used before cinema4d and maya and knows programming in these months the most complex VEX was a 2 liner.
He has done 2 customer projects and new projects will be done in houdini.
I helped him alot at the start and now just when there is a problem that he can't solve.

Good luck!

is there a typical time of the year when new houdini versions get released?

Yes and No
March or October where some releases but no date is safe. SESI is too funky in that case but when they are very quiet it is near.

Btw. 18.02.2024 would be a nice date that would be 10'000 days after H1.

probably pretty simple, just add multiple refract bsdfs together. You won't get any neat tricks with polarization though.

okey thanks, will test that out.

I was asked if Mantra or karma has the possibility of Rendering Double Refraction Material.
Because my shader knowledge is just in the base level it would be nice if somebody has some advice's, tips.

i add some links that i have found about Birefringency.

Houdini Lounge » Odd behavior with Karma CPU

Or maybe is that XPU is ignoring bad geometry and CPU is rendering it properly.

I would say maybe the Shader has functions / textures inside that XPU ignores and Karma CPU is using it. Or the Mesh has Attributes inside that gets wrong used.

What you can do:
Check the Mesh in Spreadsheet if there is something a Special Attribute or Normals(N) in Point or in Vertices you also can import in /obj and check there.
You can add for Testing a SOP Normal (Vertex or Point) and check if it is Better.
change the shader to a MTLX Standard Surface does it look same.
use a Default Mesh (Box, Sphere) and check if the shader works on both Karma(CPU, XPU)

I don't have a Apple M1 and i also don't know how XPU is Working on a M1 CPU/GPU.
When you find it could be a bug then it's required to report to Sidefx:

Dassault has left the forum

Huge complex products are developed with Catia V5 or V6 and they don't win the beauty contest.


I have to say small updates on the UI would be nice.

I think it is a safety for the users because the data can't be copyed by index bot's.

Virus developers can't use the forum as storage for there attacks.

It's logged who downloaded the files.

I don't know the canadian law or if there are special regulations. But it helps in such cases when you know who is the publisher and who is the downloader.

Godot Engine is becoming very popular, and is probably one of the most widely used game engines, especially by independent developers. Would it be unrealistic to wish for Houdini Engine for Godot to become available, perhaps not in H20, but in one of the next major Houdini versions? Is this being considered in SideFX's long-term plans?

Made 4 years ago a proof of concept. I asked for some help and i didn't got feedback or intresst. The godot file format is simple and with gltf i think the complexity for integration is lower.
The video is old and i had also made a small code update where the instanced objects are in a csv file and the points in a csv file. Thanks to that the load time is way faster.

-Kill Mantra in favor of Karma.
-try to end redshift's hegemony in favor of materialx
-GPU Multithreading pyro solver.

Thank you! Finally someone who agrees that Mantra shall be dead!

Mantra is EOL since H18 the development is fully on karma. They just didn't removed from houdini because it is still a solid render engine with many functionality.

Mantra is EOL so no new developments. Karma and in vulkan they are investing ressources. Everything is fine

The reason why houdini exist is where other tools fail houdini will solve the problem.
I am sure H20 will bring many cool things it takes time and beer. To overcome the waiting...

You can try the older builds.
H19 or H18.5
https://www.sidefx.com/download/daily-builds/?production=true&python3=true [www.sidefx.com]

For start learning the basic are the same.

When you can install linux or windows on a seperated volume it could MAYBE fix the problem.

Why not build a standalone Compositing app? We need some real competition to Nuke or it will remain the same for next 20 years too! Most Compositors are completely fed up with lack of development and legacy bugs!

Not required, have you seen the price tag from nuke vs houdini core?
Houdini core is 2k$
Foundry Nuke is 5k$

If houdini core/fx can replace nuke in the production nobody needs a standalone composition app.
