rendered a dcm .exr from h13. However, the .exr is black in nuke8v1. In mplay, the .exr is not black.

In nuke8, the DeepSample node could display sample data.

Using iinfo dcm.exr, the WorldToCamera and WorldToNDC matrices are all zero. Is it a bug?

HI，it works only nuke 7 ,not nuke 8. Maby it's a bug. I think it will be fixed in next ver.

I don't think nuke 7 support exr 2.0 deep data. And h13 mantra render exr 2.0 deep data in dcm

Nuke8.0v2 works fine now with Mantra dcm Exr2

Nuke 7 works well with Exr2 using DeepRead nodes

hey kelvin! yeah 8.0v1 deep is busted, so roll with something else.

Since you're getting into it, you may be interested in a couple tickets I filed related to Mantra's exr2:

SESI-16649 - store Zfront/Zback in deep exr images
Looking at volumetric deep samples via DeepSample in Nuke, there are values for “deep front”, but “deep back” is zero. While it might be ok to make the assumption that front=back for a hard-surface, you can't assume that deep samples are “tidy” (in-order and non-overlapping) for volumetric samples.

SESI-16644 - enable/disable toggle on deep raster planes
Add a toggle on deep raster planes to enable/disable it for DCM export; we would like to specify which channels get stored in the deep file.
