`pdginput(0, “file/image”, 1)`

if I put that in the File COP and make 1 file cop for each image, then feed into a Sequence COP, it works. Alas, this is clearly not very procedural or scalable

Hi,

Somewhat related to this (I tried the attached example file on that thread) but have failed to get this to work.

Basically, I have a FilePattern TOP (point it at any dir with non-frame-numbered images, such as $HFS/houdini/pic/hdri/*.rat) and I want to Mosaic the output.

Mosaic COP takes an image sequence, so somehow I have to get the @pdg_input to return a sequence to feed into the Mosaic COP.

In the linked thread, an Interleave is used, but that won't scale of course since that has a hardcoded number of inputs. Plus even in that case I couldn't get it to load two different frames I was thinking @pdg_input.0 and @pdg_input.1 fed into the Interleave but alas, I just get a single output in the Mosaic.

Any pointers most welcome.

I'm curious about that too, how to paint the quad density. I've tried red, cyan, blue green etc, with different Painted Quad Density numbers set and … nothing changes ever

Hi Mark,

Importing a .hip file is fairly easy, just “merge” a whole .hip file.

However, how you store and track the .hip file is IMO the tricky part. Do you have an asset system or database? If so, registering the .hip file as an asset is probably the way to go.

If you don't have such a system, some sort of storage area with a (possibly simple/basic) interface could be set up, as crude as a directory or directory structure that some Python lists. Won't scale well but would be fine for a smaller setup.

You can also do the partial .hip file like in the video (hcpio) but it's a bit more work and may not be necessary if your template .hip files are simple and clean.

Hope that's useful!

Cheers,

Thanks John, that's kind of what we expected

Yes we want to write BGEO files via Geometry ROP from inside Engine. This works fine, if you advance the frame. So I guess it's a Maya side tool that would do that? That's fine btw, just wanted to explore all options.

We're running HARS in a separate process, so I was thinking RPC ports between Maya and “Houdini” (i.e Engine) might work?

Hi,

After reading through the articles I could find on here, I see that some sort of scripting/hacking is needed to move Maya's current frame then cache a frame out etc to get animated outputs cached from inside the HDA.

Is there any way to script this from inside the HDA? I.e. is there Python/MEL access to Maya from inside the HDA?

If not, what is the best approach to this? I know virtually nothing about Maya but do have others around me who know it well

Cheers,

p.s. my first post in the Engine for Maya forum

Thanks for this Chris, please continue these “what's new” summaries, there is so much going on in HOudini these are super helpful!

Cool thanks Kai!

I recall the Cache LOP too, but sadly, I can't make a Cube motion blur

See attached…

DOF works, even when I don't want it Separate topic though.

Yup thanks Mark.

Thanks Mark, if 370 builds I'll give it a try!

Thanks Mark, it's obviously easy enough to work around inside LOPs, just thought I'd mention it.

Thanks Rob, it's a pre-Valentine's day miracle!

Hi Mark,

Same as goat, nada being spit out but can't load bgeo.sc files.

I also notice that Hqueue is quite flaky (machines dropping for no reason) in 18.0.367. Perhaps unrelated, but thought I'd mention it.

I can't easily test Windows currently, but if I get a chance I'll give it a try.

Hi,

I'm feeling a little dumb on on this one, I can't figure out the syntax to set the properties on the command line for karma/husk.

Also, why is DOF on by default? Since it needs to be off 99% of the time, maybe “off” for the default is better?

Cheers,

This file works fine in 18.0.355 (last time I dl'd 18 at home) fwiw.

Maybe related, likely not, I get this shizzle in my shell:

Hi,

I have an older file that loads and renders (in Karma) a bgeo.sc file created in 17.5.293

Using today's build (18.0.367 Linux) however any attempt to load in this bgeo.sc fails.

Reference LOP, File LOP etc.

When I try the Stage manager, and browse to the path where the bgeo.sc file lives, the file browser is empty as though it doesn't recognize bgeo or bgeo.sc files.

Even using a SOP Create LOP fails, the file SOP inside loads the .bgeo.sc and shows it to me in the standard Houdini viewport, but back in LOPs no primitives are created from the SOP Create LOP.

Has something broken or is something in transition or has the process changed somehow recently and I missed the log entry?

Cheers,

I was able to use a Fetch ROP pointing at Karma LOP which would use Hscript to gen the USD and render it, which worked. Not production useful of course, but at least it works!

I need to try the gen USD then render USD that you mention Chris, are there any special setups required?

Example would be especially helpful

Will there be a standard ROP setup for this at some point though, to gen USD then render it via karma without going through PDG?

Cheers,

Peter B
