Problem in 3D bluray copy

[Locutus2k]

I have a 3D active bluray of Piranha 3D. It has 2D+3D Active+3D anaglyph on one disc.
The menu shows 2 big files: one is 2D (and i suppose 3D active) the other one is anaglyph (you can tell in preview by the colours).
I've copyed the 2D/3D file only with the "main movie" option, no recompression.
When i put the disc on the Oppo bluray player no matter what i do the movie play in standard 2D. Where am i wrong? DO i have to copy the whole disc to have the 3D Active effect or there's a workaround for this?
Thanks

You copied only 2D part of it. DVDFab Blu-ray Copy that you used, can only work with 2D content. If you want to make a copy using DVDFab Blu-ray Copy you should use "Clone" mode for it. Otherwise, you can rip your movie using DVDFab 3D Ripper, but outcoming content wouldn't be in BR format.

When i put the disc on the Oppo bluray player no matter what i do the movie play in standard 2D.

Of course... see above. BTW, is your Oppo BR player 3D capable?

Where am i wrong?

There... see above

DO i have to copy the whole disc to have the 3D Active effect or there's a workaround for this?

Yes, clone it (see above). And you have to have all other 3D paraphernalia...
