ID 511770 - RenderOutputDefine parameters not respected when tile stitching

Problem summary
Tile stitching no longer respects the value of the forceLegacyChannelNames and exrBitDepth parameters. Resulting in non RGBA channel names and always at 32-bits per channel.

Customer reported version
Katana 4.0v8

Customer reported platform
CentOS 7

Steps to reproduce

These reproduction steps use the attached tile_render.katana scene with RenderMan.

1) Tile render the attached tile_render.katana scene. Example commands:

"C:\Program Files\Katana4.0v8\bin\katanaBin.exe" --batch "C:\Users\Work\Downloads\tile_render.katana" -t 1 --tile-render=0,0,2,2"C:\Program Files\Katana4.0v8\bin\katanaBin.exe" --batch "C:\Users\Work\Downloads\tile_render.katana" -t 1 --tile-render=0,1,2,2"C:\Program Files\Katana4.0v8\bin\katanaBin.exe" --batch "C:\Users\Work\Downloads\tile_render.katana" -t 1 --tile-render=1,0,2,2"C:\Program Files\Katana4.0v8\bin\katanaBin.exe" --batch "C:\Users\Work\Downloads\tile_render.katana" -t 1 --tile-render=1,1,2,2

2) Stitch the tiles. Example command:

"C:\Program Files\Katana4.0v8\bin\katanaBin.exe" --batch "C:\Users\Work\Downloads\tile_render.katana" -t 1 --tile-render=0,0,2,2 --tile-stitch

3) Inspect the stitched "lgt_distant" EXR's metadata.

Expected behaviour

The channel names are B, G, and R as forceLegacyChannelNames is set to "Yes". The channels are 16-bit.

Actual behaviour

The channel names are lgt_distant.b, lgt_distant.g, and lgt_distant.r. The channels are 32-bit.

Workaround
Unknown.
