Problem summary When exporting a layer from Mari as a psd file, programs outside of Photoshop will interpret this export as a full white render
The cause of the issue appears to be related to the layer being embedded into the psd file, but not set as the primary (RGBA) layer.
Customer reported version mari.4.6v4
Customer reported platform windows10
Steps to reproduce
1) Open a new Mari session, and create the example head project
2) Within the 'Layers' panel, right-click the 'Diffuse_Colour' layer, selecting 'Export > Export Selected layers'
3) When the Export Manager opens, set a file location and rename the template extension from '.tif' to '.psd', then select 'Export All Patches'.
4) Once the psd files are generated, attempt to preview them, or open them in a program that interprets psd files (that is not Photoshop), for example Nuke or Maya. Result: The file will be interpreted as a full white render
Expected behaviour layers exported as psd files should contain the layer in the RGBA channel and not embedded as a separate channel.
Actual behaviour layers exported as psd files result in a full white render in the RGBA channel.
Workaround There are two workarounds for this issue:
1) Open the psd file in Photoshop and resave
2) Open the exported psd files in a program that interprets photoshop layers (eg. Nuke) shuffle the channel to RGBA and re-render.
