Hi there !
I have in my houdini file a COP2 network making some changes to textures on my hard-drive, and then outputting those textures with a ‘ROP File Output’ node.
Those textures are actually a set of Masks, each channel is a different mask (R=Metallic,G=AO,B=Emisside and A=Smoothness)
This is working nicely, but here is the issue:
Those outputted .png or .tif files are using the alpha channel as transparency, and if I open them with Photoshop, there is no accessible alpha channel, and instead all my RGB channels are displayed with transparency.
Basically, I cannot use those textures as they are, they are completely impossible for an artist to author in Photoshop.
Is there any way to export/render a COP network into a .png or tiff file, and keep a clear visible alpha channel, accessible in Photoshop ?
