Hi does Octane have a shadow matte material ?
A material that catches the shadows to comp into a backplate ?

cheers

not at the moment no.
i could add one, if there is more demand. (i have already a large list of things that a lot of people need to be implemented first)

is there ? anyone else ?

I don't use it but I know how important it is, specially when you work with HDRI, since they are mainly made for compositing 3D in real images

That would also help for people that got 3D tracking in host app, and need to render plates in Octane

Its more a professional feature, very specific but usefull

Its a must for my Arch Vis work, a lot of the time I'll take location photos and drop the building in.
If theres no shadows casted by the building it ain't going to look good :)

cheers

what about adding support for loading images and compositing/rendering over them in realtime too?

you could tonemap your render over an image, or both.

+1 for a shadow catcher. In-camera matching and tone-mapping is not something I would use probably - rather have the flexibility to do it in Photoshop anyway.

This could be nice..Furthermore, about animation, if Octane is able to animate camera it could be very usefull to import animation data and background sequence plate and do live action mixing. Just a suggestion..

That would cool but not essential.
I find I normally load a background image in to do the camera matching, then do the comping in photoshop/aftereffects.
Camera matching tools would be nice, like sketchups.
I hate using 3dsmax camera match tools, I normally do it by eye.

+1 for shadow catcher and +1 for alpha-channel ... its usefull to render a very complex static background-scene and then render only some moving objects for compositing.
