not 100% sure what you mean but to crete a line between 2 already existing points you can use the add node.

then you can remap x to the line and y to an arbitrary line that is 90 degrees from it.

I do a lot of modeling in Houdini, I came from 3DSM to Maya to XSI back to Maya and now to Houdini and I can tell you that modeling in Houdini is a better experience than all the rest. If you don't want the long chain of nodes just delete the history like you would in any other program and all the nodes will be gone.
T.

I find that packing certain sections in a subnet is the cleanest and allows me to backtrack often.

Pavel Breiva
Hi, would like to talk about the old as the world of computer graphics topic - MODELING.

Particularly where the pain starts.

Houdini modeling tools are unique and perfect for procedural modeling and overall procedural structure and other very cool stuff.
BUT, what if in certain parts you want to jump in and just quickly blockout smth destructively, without having your node chain to grow significantly where you can be lost, where you could be able to do it quickly and not to spend 3x time on it?

Modeling is a demanding stuff, and I want to be creative, achieve results as quickly as possible, and not being destructed by creating nodes for each blockout step without need.

Theoretically there is Poly Draw/Topo Build nodes, which are solution for current situations, but far not enough, these are abandoned and stuck in the past with limited functionality, not to compare to modeling packages functionality.

Why not to increase Poly Draw potential, make it more similar to Zbrush Z-Modeler tool/brush for example, where you could just jump in and quickly inset, extrude, drop primitive, make more flexible splits, align edge/points in more flexible way, add Edit Sop functionality to it with peak, soft move etc.

I believe(probably) it is not a big resource for development but could be relatively big step to make Houdini a win-win package for quick modeling also.

YOu can ezsaly set up a workflow that is faster then maya or z modeler. just right click the tools and ad a keybind to them.
Now you can model super fast and with a lot of tools semi procedural.

There is also a payed addon that is basically this but al the keybinds have been set for u. and costum tools have been added.
you can find it here. https://www.youtube.com/watch?v=Y_SI5MMWkYs [www.youtube.com]

Technical Discussion » Save as amc ? Motionclip .bgeo 27 MB vs 1MB amc vs 7MB FBX


NicTanghe: 109 posts; Offline

2023年2月2日 10:34:38

Hello

I’ve been looking at transferring motion data from 1 rig to another and i noticed that the storage space requirements for motion clips as BGEO are way larger than the .amc files.

Is there any way to safe a animation data as an asf + amc instead of as FBX or Motionclip ?

Houdini Indie and Apprentice » How are you converting your images to ACES on a MAC?


NicTanghe: 109 posts; Offline

2023年1月22日 09:05:56

Hello,
THe best way to setup Aces is to first download a profile.
I`ve added mine below since for some reason I cant find the githuib page with all the verions.

Then you need to set it up in your .bashrc file.
https://stackoverflow.com/questions/19662713/where-do-i-find-the-bashrc-file-on-mac [stackoverflow.com]

With the following code

export OCIO='path/to/config.ocio'

Then you can use hoiiotool
below is an example of converting scene_lineair to sRGB

hoiiotool -i input.exr --iscolorspace "scene_linear" --ociodisplay "ACES" "sRGB" -o output.jpg

hoiiotool is in the binairies folder of houdini

you can also just init the houdini env in your bashfile using
(note that i`m not sure if houdini also installs in opt/hfs/ in mac

initdir=$(pwd)
cd /opt/hfs19.5
source ./houdini_setup
cd $initdir

Solaris » Hairshader rendering haf of the hairs as white ?


NicTanghe: 109 posts; Offline

2023年1月21日 13:11:54

Hello,
I had a grass shader but lost the full scene and only have the shader left.
When I try to use the shader now, the karma hair shader behaves weirdly.

When subd is not enabled, it only puts the color on the points.
If subd is enabled, it only puts the color on half the ribbon ?

I am very confused by this and don't understand why this is happening, I thought I did the exact same thing.

Below you can find a simplified scene.
Any help is greatly appreciated.

I've been developing on Rocky Linux 9 for a while now and haven't run into any issues besides the aforementioned problem with the Help Browser.

Hello i have been on RHEL8 to avoid the browser issue but omni-verse has forced me to switch to RHEL9.

To my surprise the help browser doesn`t work still.Can i get a status update on the bug report ticket ?

Solaris » Asset Library Materials Duplicated for each asset


NicTanghe: 109 posts; Offline

2023年1月15日 07:40:50

Hello,
I have converted an KitBash3D asset pack to AS USD library, so it appears in my asset browser.
The Library, however, takes up a large chunk of storage space as it duplicates all the textures for each entry.

I was wondering if it is possible to just have the textures as a separate USD entry and still have it work in the asset library.

I realize I Could also just make softlinks so a folder with all the textures, but I'm wondering if there are other methods.
Because I’d have to remake all the links every time I edit a texture variant and save the component.(I Think)

Solaris » Shadow pass in XPU

Reflection catcher is just enabling the specular / diffuse / emission in the settings of the node.

I do agree that this is the most lacking feature in XPU.
I had hoped this would be in the 19.5 release

I really hope they can put this in the next stable release.
