[HOU-1386] resolution overscan?

[docaml]

Simple, is there a way to render with resolution overscan?

I don't know about in Houdini, but in Maya if you go to the overrides tab in the camera, there's overscan options there.

In camera > View Tab. There is Screen window size. Maybe is what you searching for ?

[Gosho.Genchev]

Buck docaml currently those are not available in Houdini. I've logged it as a request and if everything goes smoothly, the options should be available in the next nightly.

Cheers!

Hi guys, actually screen window size in "View" tab of the camera is supported and will be applied to the final render, but it won't be saved in exr metadata.

even from Vray in Maya, when the exr is rendered and brought into Nuke, you have to put a reformat on the image to get overscan visible. you can see the bounding box larger than the image, but have to reformat the image to get the overscan pixels visible. Is this intentional? Not really a huge issue, but might be nice if we didn't have to do that

[docaml]

Yes, screen window size is doing the job. It would be better if overscan could be defined in pixels, rather than scale multiplier, but nevermind.
Thank you guys!

We implemented the Houdini way to set the overscan, because it is visible in the viewport. If we add the V-Ray for Maya settings in ROP, the won't be showed in the viewport. But I can add this in todo list

[docaml]

chakarov for me, it is fine as it is. Maybe, that comes on my mind, if someone wants exact measurement of overscan in pixels, it would be handy to have that option too, but I do not know how to implement that and keep "houdini window size" way, as it is now.

Hi!

chakarov - Has a way to output overscan in the exr metadata been implement? Or is there a work around with Houdini vRay todo this?

thank you!

Buck That's how EXRs are supposed to work.
It's handy having the view window set to the plate res and the overscan being in the the data window.

[psantos]

That’s exactly what I’m after. But when using the Houdini “screen window size” it changes the actual output render to have the crop to the filmback+overscan, as opposed to have the render displayed as filmback and have the overscan in the metadata/header of the exr.

is there a way to work around this behaviour?

The more I use the built-in v-ray overscan, the more I'm finding I do like it like this. I guess I had just been used to manually making the overscan with the camera and resolution.
