Hi Juanjo,
Is there a way to display a background plate in the ipr and have a separate hdri as the enivroment lighting?
Thanks,
Shane

The next plugin build is going to have this new feature:

Added a new "visible environment" pin to the render target node. If specified this environment is used for reflections, refractions and all camera rays that leave the scene and the regular environment is used only for the direct light calculation.

But I am not sure if this is what you want. Are you talking about some kind of compositing function using the alpha channel to add a background plate to the rendered image?

That sounds like just the thing I need thanks!

Would be useful to have the optional input that is only camera rays , but ref/refrac/light are all env.

I too am looking for an option that would allow me to add in a 'background plate' and have that show in in the IPR for reference.

It really helps when you're trying to add in 3D objects into a scene.

Thanks,

Jim

Flat background plate is one of the nice things that I used often in octane for cinema 4d. But don't have in houdini's octane plugin.
This function would be very useful and handy.

Any news about this great feature in the most powerfull render engine in the world? when we can add a flat bg on the render?

This feature will be available probably once we have ready the new Qt based IPR, but meanwhile, how about using MPlay as IPR viewer when you need to work with background plates? ... I know that the MPlay IPR has some limitations, but on the other hand, it supports the background plate feature without problems.

Thanks,

I am also trying to do this in 3dsmax .... any update on this ?
