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

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.

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
- 2544 posts

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?

Hi All,
Extreme noob here asking a question that may have been answered before. I CTRL-Click to lay down an Ocean and then setup a camera. When I render, however, the result of the render does not look like my viewport.
What is going on here?
How would I plan any kind of animation if the resulting render does not look ike my viewport?

Houdini Indie and Apprentice » Crashing With Unattended Render?
- Enivob

Hi All,
I am trying to render a scene. It takes a while. Yet every time I walk away from the computer and come back Windows has crashed and rebooted. So it appears to be a BSD. This only happens when rendering with Houdini 13. My system is very stable otherwise. I think this has something to do with power saving settings. I can't confirm this yet but my guess is that when the power management kicks in Houdini crashes.
I also have similar issues on my Mac mini running Apprentice. OSX does not seem to think that rendering under full load constitutes the computer is in use and idles down the CPUs to a slower Megahertz when it's sleep time is reached.
Is this a known issue?
Is it expected that we are supposed to disable power management to use Houdini?
