Tiled EXR procedures

Hello. Is there any tutorial or doc about using tiled exr? I have 16mpix city texture and I think it is a perfect candidate for using this vray feature. But how to do it? Step by step… Also, i doubt it, but does gpu supports this feature?

Best,

If you have further, specific questions, feel free to ask.

Thanks, great resource, finally started using proxies correctly. Does GPU in Vray Next support exr tiled maps? Had no time to test it, but I doubt it…
