Hello,
I downloaded a USD asset with some materials/textures attached already.
I want to import it in SOP to do some modifications to the geo and a little animation, I use "USD Import" sop.
Then I want to go in LOP and import this sop graph using a "SOP import".
Or Maybe later I will cache SOP's modifications back into a usd file.
Problem is that I loose the materials...
If I use a "reference" LOP, it's working as expected.
Help please

PDG/TOPs » Python script to refresh attribute
- Mikel Zuloaga
- 9 posts
- Offline
Hello,
I'm trying to get the creation time of frames and put that in an attribute to later put this attribute in an overlay.
The problem is that when PDG generates the work items the attribute is not created yet, it's only created when the python script cook.
So the overlay appears empty.
I tried whith Dynamic work item generation but it breaks the rest of the depedency chain for any reason.
How can I force it to refresh the work item attributes after the python script cooked?
Thanks you

PDG/TOPs » Houdini 18.5.499 Deadline Sandbox Error

Hey guys, I had the same problem , and after a few hours of research I found the solution:
Your deadline scheduler needs to be like that:
AND
You need to copy the PDGDeadline plugin folder from *HoudiniInstall*/houdini/pdg/plugins/PDGDeadline to *\DeadlineRepository10\plugins
Works like a charm now
Let me know if it works for you.

PDG/TOPs » Python processor fetch files

Houuu thanks man ! Excatly what I want!
Now I want to perform operations with COP and export these files using “rop composite output”.
I have houdini 17.5.460 at work and it looks like it doesn't work with .exr … just .jpg
I tried on my own machine with houdini 18 and everything is fine.
Is there any bug on 17.5 ?

Hello,
I would like to fetch files using python into work items.
I have an array of file paths and I want to create a work item per file basically to process them.
Same way as the “filepattern” top but with python processor.
I can not find the python way to do that.
Thank you guys

Houdini Lounge » Recursive loop and Solver accumulation

Hello, I'm trying to accumulate an attribute inside a recursive loop.
I have a geo that enters a feedback loop multiple times and takes modifications.
The loop is in feedback mode so it uses the result of the last loop to modify the geo again.
I have an attribute that changes over time before that loop, and I want, for each iteration in the loop to be able to accumulate this attribute before I modify the geo (because the modifications uses this attribute ).
to get something like:
-accum input attribute
-change input with accumulated attribute
-accum first loop iteration attribute
-modify first loop iteration with accumulated attribute
-accum second loop iteration attribute
-modify second loop iteration with accumulated attribute
I can not share what I'm trying to achieve, but there is a super simple example file that demonstrates the goal. (I now that in the example I just could put everything outside the loop, it's just for demonstration)
The solver inside the loop kind of work, but become suupppeerrr slow with more complex stuff.
Does anyone have an idea how to do this ?
Thank you

Technical Discussion » Vex became super slow "duplicating input"

Hello,
I have this problem since a few days now on Houdini 17.5.460
When a drop any vex related node (point vop, wrangle, mountain …), Houdini freeze for 1-2sec when I drop the node and it freezes again for 1-2 sec each time I try to change a parameter and it says bottom left “duplicating inputs” and “executing vex”.
It only happens when the viewport is visible, so there is some problem with vex and viewport.
I have a GTX 1060 with updated drivers from nVidia (445.87).
Does someone have an idea what could be the problem?
Thanks

Technical Discussion » Fake Water for RBD

Hello everyone,
I'm doing Ice falling in water, it's a fractured packed object with bullet solver.
I want to make a force field in a area to fake water contact (slow down the fractures and maybe some fracture come back to the surface and float).
And I will do the water next with the rbd cache.
I tried to add a flip solver to the DOP but it seem not working well with packed object (and I have to keep it for activation).
If someone have a suggestion I put a test scene here.
Thank you for your help
