I considered the object merge and may still go that route, however, I want to use all the objects in a FLIP RBD sim and I wonder how efficient that would be and if it might introduce solving anomalies.
In essence I really just want to re-write the existing nodes paths into another parent.

HI All,
I am importing a bunch of DAE files and they come in as a file inside geo that is inside subnetwork that is inside a subnetwork. This makes the selection tool work incorrectly. There is no way to select the object, with one click in the viewport. Sure I can select the node in the network window.
What I would prefer is to simply have all the mesh data from the DAE in a single GEO node.
I am wondering how to cut/copy all the children nodes from the bottom of the subnetwork into another fresh top level GEO node?
Does anyone have any python code preform such a task?

Isn't 2GB a file size boundary on some systems? I know it is also a limit on certain types of network drives as well.

I just imported 100 DAE files that were named exactly as I wanted them. However, after import Houdini has named them all sequentially like collada_scene01, collada_scene02. This makes identifying them in the network view impossible. :cry:
I wish Houdini would just name them a derived version of the original filename. Something like… collada_my_file

Houdini Indie and Apprentice » Selecting Entire Subnet Object?

Hi All,
I''m not sure why this is going on, but selection is working funky. I have imported 100 DAE files into a scene so each one comes in as a subnetwork.
I press the S-KEY to activate the selection tool and click on an object in the 3D view and I am brought to the subobject level. I don't want this I want to just select the entire subnetwork in the viewport. Just like clicking on the subnetwork node in the network view.
Can Houdini be configured to select that way?

Houdini Indie and Apprentice » [SOLVED]Decal Like Effect Using Mantra Surface?
- Enivob
- 2551 posts

I thought about the Decal preset but in one of the new training videos for R13 Ari Danesh mentions that we should just use Mantra Surface all the time because there are some new global variables, or something, that are built in for PBR.
I am not doing anything that advanced but I wanted to try to stay entirely in Mantra Surface. It would be nice if there was simply a way to invert a Map directly in the interface like most other 3D packages have in their material systems.
I guess I'll try the decal.

Houdini Indie and Apprentice » Python In Callback For Button Parameter?

Hi All,
I have a NULL with a python script node inside with a single print statement. At the object level of the NULL I have added a Button to the parameter interface.
How do I link the python module in the NULL node to the button?
What do I put in the callback script field?
Thanks

Hi All,
I am trying to make a simple effect.
I have a sphere that I have added a color node to to make it red.
I have a RGBA PNG with alpha that has white grid lines and hollow spaces.
I have a mantra surface that is using the PNG file as a color map. I assumed the alpha would be honored but it is not. When I apply the material to the sphere object I get white grid lines and black solid areas.
So I apply the same map to the Opacity TAB and the sphere becomes hollow except for the grid lines. Is there a way to invert the alpha on the Opacity TAB?
What I want is red sphere with white grid lines.
I realize I could do this with two spheres, but shouldn't there be a way to accomplish this simple effect with one?

@MagnusL3D: How did you get the tube/cylinder to work? I replaced the grid object in the ForEach with a Sphere object and I did get the curves to conform to that shape but I lost the overlapping effect.

Hi All,
I have been trying out the PyroFx and while the sims move in a realistic way, the resulting renders look very cartoonish. I have scoured the forum looking for example files and even the threads that offer tweaking methods are kind of out-of-date and contain instructions that no longer match R13 panels.
Are there any R13 centric tutorials out there yet?
Even something as simple as this campfire image would be a big improvement over the shelf tools defaults.

Hi All,
As a new user I am working my way through the tool shelf and I have come to cloth. I am a bit shocked at how slow Houdini cloth calculates.
Why does Houdini only use 1-CPU to calculate the cloth sim? How do I turn on multiple CPU calculation for cloth in Houdini? If not that, any tips on speeding up cloth calculations?
Blender and C4D seem to be 10x faster for the basic plane draped over a sphere test.

Houdini Indie and Apprentice » [SOLVED]Ocean Render Does Not Match Viewport? (.piclc bug)
- Enivob
- 2551 posts
- Offline
Thanks for the hint.
I watched this video for more info. Mainly connecting the Fetch node to the input of the Mantra node.
https://vimeo.com/84903041 [vimeo.com]
However, there is a bug in this workflow.
It seems that Houdini Indie writes out files in the form of .piclc instead of .pic.
This means the path to the displacement maps setup by the shelf tools is invalid for Indie users. You have to select the Ocean Volume shader in the SHOP network, locate the Displacement Map field under the Displacement tab and manually change the extension of the displacement map from .pic to .piclc. I wonder if Apprentice has the same problem with .picnc?

Hi All,
I CTRL-CLICK to lay down a Sphere and then I click on the Flames icon under the PyroFX tab. When I play the sim I get flames rising from the sphere. What I want, however, is the flames to emit in all directions from the sphere without any upward motion. There are a ton of options for PyroFX and even though I have messed around in a lot of the panels I can not figure out how to remove the upward direction of Flames.
I am trying to make a Sun.
Does anyone know how to make a Sun?
Is Flames the way to begin or is there a better approach?

Houdini Indie and Apprentice » [SOLVED]Why Does Flipbook Re-Cook My Sim?

Thank you, that worked.
I placed a File node after the Gravity node in the AutoDop network and then played through the frame range I wanted to flipbook. After the cooking I issued a flipbook render and no more cooking occurred.
Is there a specific reason why this is not the default? Is that just to save disk space?

Hi All,
I notice that when I use Houdini on OSX the function of the Delete key does not work. I have to use the Backspace key instead.
Is there a fix for this?
I would like to swap these two keyboard mappings to make it more compatible with Windows style operations.

Hi All,
Noob here playing with the Ocean Shelf default. I CTRL-CLICK a wave tank and press play to cook it for 120 frames. I can scrub and no re-cook occurs. My machine will not playback the result at 24fps (I only get 1.6fps out of viewport playback). I decide to make a flip book so I can view the animation, however, Houdini decides it needs to recook everything on every frame change.
I thought the point of cooking was to look in the calculations for better performance? Why does flip book need to re-cook my sim that I just cooked? Shouldn't the software already realize a valid cache is available somewhere?
Am I missing a step? Do I need to place some kind of node at the end to preserve cooked data?
