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.

wanglifuWasn't there a roadmap in the H19 presentation?raincole
I guess it's a sooner-or-later, but I really hope Karma XPU and MaterialX get production-ready in H19.5.
Probably not,maybe two years later.
Mid 2022 for XPU beta
End 2022 / beginning 2023 XPU production state.

VEX comes more from RSL but it has more like c++, javascript syntax.
It is not hard just it takes some time to understand. Python is a bit diffrent but just try to learn it. When you know the basic of programming both languages will be easy to understand.

does Blender run native on a apple M1? what i know is that cycles has M1 support under development.
cinema4d had a huge rewrite at the core and viewport that has been started years ago.

i am pretty sure sidefx will do a metal based karma render engine, but that that will come when the XPU will be production ready.
currently apple M1 is still new and it just takes time, in one year we will have more information.
if houdini will have native support for M1 that is another question.
