Same issue in 20.724, fixed it following the above suggestion with this script:

export LD_PRELOAD=/opt/hfs20.0/dsolib/libHoudiniUI.so
cd /opt/hfs20.0
source houdini_setup
cd -
/opt/hfs20.0/bin/hindie

I downloaded that config and manually added the default view line and then put the path to the config in the ocio.json package, and I'm seeing the tcamv2 view preselected in the viewport on startup. Is that not what you see?
I went 2 ways
- initially added the path to the config to the houdini.env file
- then tried the same path through as the OCIO varibale through a sys env variable
both ways led to the config being read, but left me unable to change the default view transform (it did add the default part to the (houdini created) config however but restarting houdini removed/changed it again for some reason). so removing the variable before restarting houdini was 'a' solution for the time being
guess i could try going through the ocio.json file instead - thanks again for your input!


Have you managed to set it up correctly? Deleting before restart allows you to maintain the settings but highlights look completely clamped in the viewport.

You should really calm down man, because a lot of what you said is not true.

I'm a Blender AND Houdini user and I know what I love and hate about both. I actually believe that the two are a good fit for each other because Houdini doesn't have sculpting, 2D animation (grease pencil), 3D tracking, video editing (if needed) and can be tedious to do destructive modeling in it. Blender, on the other hand, sucks major times in quite anything related to physics, handling of large scenes etc.

So instead of taking it too personally, embrace what can be done with it - in the end it's just an egoistic thing, we use these tools for our own needs.
This is my opinion based on my experience with Blender and the BI, you may not agree with it, but it doesn't mean that I am wrong!


Not sure if you live in 2013 but blender is rocking right now, so you are completely wrong, the best one can do is use both to their fullest and balance their weaknesses.

For me it's not so much that the UI isn't useful and well sectioned but that overall feels slower and tedious compared to Blender, not to mention it breaks constantly (specially on linux). And there are lot's of other interactions to improve, overall it seems you are closer and in direct relation to the scene in Blender, the right click to select + g/r/s + mouse movement it's quite a bit faster than, S + click + T + Middle mouse + movement.


You can see it in the comparison, Houdini greys out the scene, is full of glitches and laggy, while blender resizes the scene window, it's clear all the way and silky smooth. 5120x2160p so it's quite a stress test.

i think you are joking right now. like i said, apply triplanar, ramp, anything - it will fail. surely you cant be serious
What you are saying is that XPU is still in beta and not everything works, is that it, I am shocked! 😉
i explained it above - you are using wrong material definition, and your example is incorrect. i am not sure what exactly you don't get

People talking with authority yet are ignorant on the most basic of Houdini features...

ML skinning sounds exciting , I really hope there are plans for a nice ML framework to use all kinds of models.

edit: based on "And a foundational SOP & TOP toolset for Machine Learning using ONNX" it seems to be happening.

You are using "biased" as if it meant something for you, have you done research on what is actually biased or you are just spouting it? I use both Houdini and Blender, and it's much better than using any of them alone.

3900X / 56gb 3266mhz / RTX3060(12GB) / W10 19043.1288

Pyro Scene:

XPU: 0:22
CPU: 10:20

Rhino Scene:

XPU: 3:04
CPU: Too long, Elapsed: 31:00 - Remaining: 37:58

Below a comparison between Karma XPU, Cycles-X(1024samples), which took only 18.6 sec, and Cycles-X(200samples) with similar noise to XPU, at 6.23 sec, yes. All in ACES, same hdri, materials, rhino was using glass shader instead of principled transmission that looked very dark, no time difference.

So in this test, XPU was an order of magnitude faster than CPU, and Cycles-X another order of magnitude faster than XPU .
XPU is in alpha, and Cycles-X is a biased version of Cycles, therefore much less precise than Karma, I don't see the point of comparing Houdini to Blender, Houdini is way more powerful than blender, which is why I switched to Houdini, I got tired of hitting a wall with blender all the time, Houdini might not be free, but with it I am free of the limitations of blender!

I smell a bit of salt? Cycles-x just barely go out of alpha, and the biased argument is just funny, but hey if you are happy thinking that...

Buying 3Delight makes no sense, SideFX already has a production CPU engine in Mantra - and SideFX clearly accepts that CPU engines are a legacy product - as SideFX has literally stated, they are not investing in their Mantra codebase anymore.

You don't even have to buy it: first license is free for commercial use And you get 1000 mins of free cloud rendering.

… GPU is the future and AI has just begun its disruption in the 3D/VFX industry.

No one can really predict the futur but I don't see any disruption coming from AI and GPU on the production side of things in the medium term at least.

It's already starting, in the next 5 years we'll be surrounded by AI tools in 3D productions. One example: https://graphics.pixar.com/library/SuperResolution/ [graphics.pixar.com]

What in particular do you like?

I also love that hitting the keyboard letter of the axis, restricts the move/scale/rotation to that particular axis. It's such an incredible time saver and it's so intuitive that I don't understand why others don't implement such a simple thing.


This was the first thing I changed from their system back to the traditional axis/gimbal style. It's so confusing that the object does a transformation right away which you then have to restrict to the axis you want it to move. I don't want to look/think about the axis I want stuff to transform.

So you want it to transform itself. Blender does really have a more intuitive transform procedure, with CAD Transform addon it quite nice. In vanilla you can use middle mouse to transform the object in the general direction of the mouse movement or just shortcuts to restrict it by axis.

Well after testing Houdini version of box cutter I have to say I feel a bit disappointed ☹️.
In Blender version You can start creating box, circle and custom shapes by default, tried to create a circle in Houdini and it did not aligned automatically to the surface face, it did not keep proportioned so you need to eyeball a perfect circle shape,
In blender you can Trace your shape and use shortcuts to do many actions such as union, substract, Cut, etc.
You can recall and reselect all the shapes you cut visually using Hardops.
You can perform Cuts and tweak all the cuts you did as if they were individual objects,

And the list goes on and on.

Houdini's attempt, Unfortunately is light years behind Blenders.

Hmmm

Yeah, some modelling tools like hops/bcutter would be nice, these in my opinion give blender the edge in all the modelling landscape, despite what other “industry standard” software users try to believe.
