Override support on the GPU

V-Ray V-Ray for Maya General
1

Hi all

Any progress on the Overrides GPU support. Even if it’s just the Background, so we can render the floor reflected back in to the geo on the GPU?

Cheers

Material Override is supported but Environment Override is not yet supported.
I’m not sure what exactly you are trying to override, can you send me a sample scene so I could better understand?

Hi Svetlozar

Yep, I’m after GPU support for the Environment Overrides.
We work on a lot of Automotive shots, where we require control over these settings - floor plane projections etc.

The GPU support has been requested a year ago or so, and I was just after an update.

Cheers

It was discussed here,

Thanks for the feedback. I’ll discuss his matter with responsible developer.
Just to ensure we are on the same page, you are talking about V-Ray Material Override attribute > Environment Override option here:

Hi Svetlozar

I’m after the ‘Override Secondary Matte Environment’ support on the gpu.

Please read this post from a year ago:

Even if we can have the Background support, we can assign a wrapper to the floor plane and have the background plate reflect up in to the car.

Cheers

Thanks, it’s still not developed but I’ll raise it as a question for future development.
Can you explain in detail what’s the use case for that? What exactly you are after and isn’t there another way to get that result?

Looking forward to hearing from you.

Cool.

Here is how we work on the CPU:
________________________________________

Wrapper on floor Geo
Matte for all secondary rays - With Projection Mapping

Render Settings
Environment
Override Environment - On
Override Secondary Matte Environment -On
Background texture - placed background plate/image
GI, Reflection and Refraction textures - we occasionally use these.
________________________________________

When switching to the GPU, the Secondary Override does not render.

Please let me know if you require any more info, as we would like add our GPU’s to the preview and final renders.

Cheers

Hi Svetlozar

Just checking in on any progress?

Cheers

10

Any news on the Background texture support.

11

I’m sorry to inform you but it looks like it’s not that easy to implement those overrides for the GPU rendering.
We are still thinking ways to do that, not sure how much time it will take us to do it.

12

Ah, that’s a shame.

Please keep me informed, as we heavily us the Background feature, and so currently we can’t use the GPU for our rendering.

13

Will do it. Thank you very much for your patience.

Hi Svetlozar

Just checking in on, if there has been any progress on this?

Didn’t spot the feature in the update?

16

No, it didn’t make to the update. It’s still on the list of things to do.

17

Ah, bummer. Please keep me posted, as I have a stack of GPU’s I’m looking at adding to the rendering.

Cheers

Hi Alex, just checkin in again, after seeing update 2 for Max.
Any news on the GPU support in Maya?

Cheers

19

We still haven’t gotten to it, sorry.

20

Ah, that’s a shame.
All the other new features look great, but can you tell me if the GPU Overrides are being worked on and have a priority?

This overdue feature request will make a huge difference in our render times - as we will be able to add in all our GPU’s.

Cheers
