As an extra step I've done, which was suggested previously is comparing the headers and they both seem identical to me.
Technical Discussion » GSOPS : noising point position and re-exporting SIBR

Hi,
Has anyone ever had to noise up the point positions of a .ply sequence and re-export them to be rendered in SIBR?
My workflow has been as follows :
1 - read in a .ply sequence
2 - noise up their point position
3 - write these out as a new .ply sequence using the Gaussian Splat export
As far as I can tell, only the P position gets updated, all other attributes remain the same (f_dc*, f_rest*...).
Is there something I'm missing? Having a really hard time getting this to work.
**Also, I've compared the headers of both files and they seem identical to me.
Any info or guidance would be greatly appreciated!
Thanks!

Hi everyone,
Resurrecting this topic given we're having some issues exporting a .ply sequence from Houdini to be read into SIBR.
Dragging this .ply into the open SIBR viewer with a camera.json file in the same folder also crashes the program with this error message :
I'm currently using the GSOPs v2.0.0 package and exporting as seen in the screenshot below. Has anyone found out how to solve this?
Thanks!

That's awesome!
Is this anywhere to be found in the hou module help? I found myself circling over and over and I didn't see anything regarding toolutils. Would you mind providing a bit more insight as to how you found this please?
Thanks again for your help J.

Hi,
I'm having a hard time trying to change the background color scheme via the viewportColorScheme module. For one, the class isn't mentioned in the help.
A little help would be appreciated
Thanks!

Hi J,
Thanks again for your explanations. It does make a lot more sense.
I understand that in my for each loop, my ‘i’ was already getting assigned the objects of my tuple node_outputs.
Hence all I needed was something like print i.name()
Maybe I don't have the right terminology but it does make more sense
Thanks again!

Hi J and thanks for your very descriptive response
I'm obviously still very new to python so there are some concepts that I don't fully grasp.
For example, when I created the object node_outputs = node.outputs() I assumed that this was returning me a list I could loop over the indices. From what I understood from your answer is that my node_outputs only contains hou.ObjNodes that don't have indices. Hence tuples don't have indices?
Thanks again for your explanations

Hi,
I have python script at the obj level connected to two other geo nodes.
I want my script to print out the names of the two geo nodes.
This is my script :
node = hou.pwd()
node_outputs = node.outputs()
for i in node_outputs:
print node_outputs(i).name()
I get this error :
Python error: Traceback (most recent call last):
File “”, line 5, in
TypeError: tuple indices must be integers, not ObjNode
What am I missing here?
If I write :
print node_outputs(0).name()
This works correctly though. So what's wrong with my loop?
Thanks!
PS I had to replace the brackets where the indices are to post this

Hi,
I'm relatively new to the world of Python and would obviously like to start implementing slowly in my practice. I've created a small script that allows me to create an object_merge node from the selected node in my network.
Please feel free to correct my coding or suggest easier way of doing thigs. Very new at this whole Python thing
Here's my code :
#selectedNodes creates an array/list of the nodes that were selected.
nodes = hou.selectedNodes()
#Me node of interest is the first one in this case, hence nodes
#print nodes
name = nodes.name()
#We need to get the full path of where to create the new nodes
parent = nodes.parent()
path = parent.path()
#print parent
#print path
#We need to create the object merge node
objectMerge = parent.createNode(“object_merge”)
parm = objectMerge.parm(“objpath1”)
parm.set(nodes.path())
objectMerge.setName(“merge_in_” + name)
#Get mouse position and print
net_editor = hou.ui.paneTabOfType(hou.paneTabType.NetworkEditor)
#print net_editor.cursorPosition()
#print net_editor
objectMerge.setPosition(net_editor.cursorPosition())
I'm running into an issue where I can't use this more than once in my network since two nodes can't have the same name. So how do we solve this?
Thanks!

Hi,
I would like to change parameter settings using the textport.
For example, how could I change the /obj/geo1/box1/sizex to specific value using HSCRIPT?

Hi,
I've been trying to have an animated fracture static object interact with a smoke simulation and have been experiencing some issues. Here are the steps :
1- create a rbd packed object simulation (in the dop network
2- cache the packed object simulation
3- import the packed objects
4- unpack the packed object into ANOTHER dop and have it interact with the smoke.
Please take a look at the dopnet inside the smoke_sim geo. I'm pretty sure this is a collision issue going on here.
Is there a more efficient way to do this kind of work? Any help would be greatly appreciated!
Thanks,
Maxime

Hi,
It seems that my ATI Radeon 7850 has a lot of issues with H14. After having reported many of my crash logs, I was told that I need to change my graphics card.
That being said, what are your suggestions on video cards? I'm still a student so I won't spend over 350$.
Let me know!
Thanks!

Houdini Indie and Apprentice » Particle spawn on collision

Hi,
I'm having some trouble trying to spawn particles on collision.
Here's what I did :
-I'm animating an object on which I`ve scattered points (see geo_points).
-I'm animating a collider that I've imported in my dop_particles
Now here's the issue : I only want particles to be emitted when my collider comes into contact with my POINTS!
Any idea on how I can do this?
Thanks!

Yes I did think of that. But let's say I want my smoke to interact with objects in my scene, maybe I don't want to rotate everything, just the fluid container.
