Maya: Tiled EXRs to scanline EXRs render option

[antirotor]

Feature

Added new option to Maya render instance Convert to scanline. When checked, it will convert produced tiled EXRs to scanline EXRs as new representation. Useful when tiled renders are required because of heavy scene but compositing apps are having problems with it or are slow reading tiled EXRs.

EXRs are converted during publishing phase.

Requires OpenImage IO

⚠️ Requires: PYPE_OIIO_PATH environment variable pointing to oiiotool binary

This is a bit strange rigth now. It keeps both representations in DB exr and exr_scanline but they both point to the same file.

I think we could keep just exr to prevent complications. we're not putting compression name into the repre name either.

I think this is because integrator integrates both representations under same name - and that is problem by its own, isn't it? It differentiate only on representation extension key {representation}. But I think it is completely ok to want to have multiple types of the same image format in representations. So:

[
    {
        "name": "exr_scanline",
        "ext": "exr"
    }, {
        "name": "exr_tiled",
        "ext": "exr"
    }
]

When this happens I guess last representation with same ext wins.

That depends on a publishing template. We have the optional <output> key which some extractors use for differentiating between various representations. Part of the problem is the discrepancy between anatomy representation and extension in the representation data. These should be the same and in anatomy should be optionally mapped to representation["name"]

at this moment. the best would be to approach this the same way as quicktimes from extract review, by adding output key to the representation data so it get's picked up by the integrator.

This will now move files to temporary names and convert to original names with OIIO. No new representation. Same files (almost as they are tiled 👉 scanline converted) at the same place.

I'm still getting the scanline in the file names

it needs to be popped from representation['output'] key
