Render Multiple Camera (Houdini)

Deadline
1

Bonjour !

Hope you guy`s are doing well. I am trying to render 2 camera at the same time in houdini.
Unfortunatly, I dont have quite a lot of succes.

I’ve been able to render out a simulation, and a single camera so far.

The plan is that i want to be able to, simulate, render the picture, and then composite the whole thing in one pass.

The advantage with houdini is that you are able to composite before rendering. So at the end you got one MOV file with the dailies on it.

But i cannot find a way to enter 2 render node in the section for it (under override output).

Also, with the plugin include in Houdini, it automaticly put an override export IFD… Why does it do that ?

Thanks for all your help :slight_smile:

How does this workflow currently work in Houdini? For example, how do you render 2 cameras at the same time directly within Houdini? Back when we initially wrote the Houdini plugin (I believe it was for Houdini 7), the workflow was select a render node and then hit render, so that’s what we based our script off of. If you can now set up multiple render nodes and then render them with a single click of a button, then it would be good to support that in Deadline too.

I checked the submitter code, and it grabs the defaults from the first render node (ie: frames, ifd export, and ifd filename). So if the first render node in your scene is configured for IFD export, that explains why the submitter always defaults it that way.

You can do multiplie render by telling Houdini network to first, render your mantra 01, and after render your mantra 02.

You can see in the graph what i am talking about.

We tried to enter in the Render Node section /out/mantra_red; /out/mantra_blue, but we got an error. Then we tried each of them separably, with still no success.

The cool part if we can get that to work, we will be able to do our compositing in advance right in Houdini, and output them in .MOV already pre-compose so we can watch our render in our dailies.

I don’t know if i express myself clear enough, English is my second language so don’t hesitated to ask me to specifies some part .

Thanks for your help again :slight_smile:

Thanks for the info! I did some reading too, and I think it boils down to the fact that we currently don’t support a way to specify composite nodes in Houdini.

Is it possible for you to post a sample houdini scene with some compositing set up already? We should be able to support composite nodes, and this would give us a bit of a head start.

Thanks!

Might not be tomorrow but i’ll ask one of our vfx artist !

Hi,

So far I have been able to get a working seen with 2 render of ready.

So the network communication is: When render_red is complete, it automaticly lunches the second render Mantra_green.

What is ode in dead line is when he is lunch that network, he should that network so then render those 2 mantra.

Logicly, each render sould have one item. But we had a little bug that render both item on both render. I figure out for you guy it`s not quite a problem yet.

Keep us in touch and thank you again (:

Thanks for the scene. If I’m understanding you correctly, it sounds like it’s working through Deadline for you. Can you confirm?

I tested the scene here with Deadline, and selected the GREEN render node when I submitted the job. This resulted in the RED node rendering first, followed by the GREEN node, which I think is the expected behavior.

Cheers,

Well that’s ode… Yeah it’s working but it’s wasen’t the first time ! hehe

I guess we did someting wrong the first time. I’ll try to figure out what it was.

Thanks for your time sir :slight_smile:
