I am using Houdini 20.5 with a custom environment so I cant really use "inherit local environment", what Deadline Command Environment keys should I use for it to work?
Technical Discussion » LOPs USD camera export as Alembic

Hi. I am trying to automate the conversion of a LOPs USD camera to Alembic and export it out.
I know you can use a LOP camera import in obj and then go to file>export alembic. But is there a way I can automate this instead?
Many thanks!
Best. Mark
EDIT: well that was pretty easy.
-add a render ROP and just change the file extension to *.abc
can you elaborate on how you did it?

Yes, switching back to the OpenGL renderer is a good fallback for some new viewport issues
I would also try testing out a newer release, if that's possible
The newest production build is 20.5.370 and should include a fix for this issue, it looks like it was fixed in 20.5.238 specifically
the first production build is 20.5.278 which is way above 20.5.238

you probably are using Vulkan which is quite buggy as of 20.5, switch to openGL from top menubar "edit -> preferences -> 3D viewports -> Renderer" then test again.

adlabac
that means our HOUDINI_OTLSCAN_PATH environment literally ends with @/otls;&
eg.
@set "HOUDINI_OTLSCAN_PATH=tool_directory1;tool_directory2;@/otls;&"
A
so how did you have that @otls;& at the end, and you digured it was causing an issue so you removed it? or you didn't have it before so you finally added the @otls;& expression at the end?

adlabacmabelzileI've tried both and it is working.
You could try to debug first locally to see if it's related to the shared folder (i.e. move the shared folder to a folder local to your machine).
1. On my local machine set HOUDINI_PACKAGE_DIR to network share(same as farm using)
2. copied shared folder to local disk and then set HOUDINI_PACKAGE_DIR thereWhat do you mean by this ?It just means that this HOUDINI_PACKAGE_DIR environment variable was set properly before render command was started.we have packages directory on the network share which is defined by HOUDINI_PACKAGE_DIR before render starts
UPDATE:
after carefully comparing all the environments, I found the reason of the missing packages. I always thought that @/otls;& endings in HOUDINI_OTLSCAN_PATH were only needed within houdini.env and not supposed it is working in .bat files.
Now errors disappeared.
I have the same issue on farm, can you elaborate? launching houdini with a batch file with "HOUDINI_PACKAGE_DIR" set will work, but when I submit it to deadline farm suddenly thats an invalid package folder, even tho the farm is working normally with that drive.

This isn't about visiblity. You probably do an object merge or reference the alembics somewhere else that involves the sim node tree. If you still cant find the issue then sharing a hipfile will help to debug

what is the recommended way for deadling with a sequence of heavy animation .usd files that I need to layer over the static .usd file.
for anim I am caching only points and velocities while the static has the bulk of the data.
geoclip sequence is slow for me but I am using 20.0.547, should I upgrade or it wont matter if I am dealing with .usd files not .bgeo?

Technical Discussion » How to link Multiparms between HDA and its child nodes?
- AhmedHindy

tamtethis works good and all, but I am creating a custom file cache which has 2 TOP nets inside like the regular Labs file cache. it should have the 'wedging' multiparm linked to both 'TOPnet Cache' and 'TOPnet display' at the same time. I tried doing it exactly like labs file cache but it can only link one multiparm inside with the outside one.
the link will be set up automatically if you promote the parms by draging the "Number Of Filters" parm into Type Properties window Parameters/Existing Parameters section
or from Parameters/Create Parameters/From Nodes section into the Parameters/Existing Parameters section

willlinksdid you manage to create a script for that?
Thanks for the reply, jsmack!
In that case, I guess I just need to extract the textures from the usd material and assign in SOP.

PDG/TOPs » Deadline concurrent tasks for MQ server?
- AhmedHindy

I am using permanent static MQserver.exe on a windows deadline farm for the past 6 months. suddenly 2 weeks ago, submitting Artist machines are failing to connect to it using the same ip address and ports. All Artist machines fail at the same time and the only solution is to restart the mqserver.
I pinged the ports from artist machines and they seem open, but houdini can't connect without restarting.
I cant find a solution to this since there are barely any forums posts about it.

Went down the same rabbit hole.. fix is simple
If you go to you're HDA's type properties -> Interactive -> State Script tab you need to press the 'clear' button in the bottom right part uit the dialog. Else you'll have a state without code. I fell in this trap when I simply ctrl-a deleted some stateviewer code I was experimenting with instead of using the that clear button.
Before you do that, right click on your HDA node and check on 'edit extra section source code', you'll see some state related files that cause the error, after using the clear button those files should be gone.
And you'll first need to add/remove a new state and handle script. Just press the 'new' button and create something, save the HDA and then press the 'clear' button in both tabs. That should clean it up properly.
Thanks that fixed my custom filecache
