3dsmax license ok for maya too?

I wasnt sure if i rememeber correctly the rendernodes are “universal”? , but if i have a license for Next/3dsmax, with some rendernode licenses, can i also use vray on maya? at least opening and rendering files? I wasnt sure if this was also the case for the interface license too..?

The interface license is platform-specific. We might release a universal one, but it’ll be a different product if we do.

ok thats what i thought.. however could i open a file in maya and render, as long as i dont need the interface?

Not really, but you can render it command line via Maya batch, this will engage only a render node license.

So, the render node licenses are cross platform, right ? I never tried.

Yes, the render node licenses are the same for all platforms.
