[Tom25865786b2p3]

Evening all,
trying to work out how to export in an uncompressed RGBA32 format, tried this https://helpx.adobe.com/photoshop/kb/optional-file-format-plugins.html however the plugins dont seem to be functioning for me on version 23.5.  any help is appreciated

According to the following link at the top of the page, they "should" work:

Please provide the full path to the installed file.

Thanks for getting back to me Stephen, I've added the plugins here C:\Program Files\Adobe\Adobe Photoshop 2022\Plug-ins\ but as mentioned doesn't work for me.

For clarity are you referring to

RGBA with a total of 32 bits per pixel i.e. 8 bits per channel - which can be saved as a PNG or TIFF or PSD file

or

RGBA each pixel having 32 bits / channel for which you can use TIFF with transparency or use the EXR format via a plug in such as EXR-IO

Hey Dave,
Thanks for responding, I'm not really sure tbh, I'm working in unity and as part of my flow I need to creat a texture mask and the file loader blocks any file with the message it needs to be in rgba32 uncompressed format.  I'm willing to try both methods if I can progress, so if you are able to provide some additional info would be great (the plugin obvioulsy doesnt need further explanation 🙂 ).

Hi

Unity will be looking for 8 bits per channel RGBA. Each of the channels can represent a different map.

So assemble your document as 8 bits/channel RGB using layers targeting each layer to a specific channel - Layer styles allows you to check a particular channel. The Alpha needs to be added separately.

When done check your channels panel to ensure your four channels RGB and Alpha are correctly populated.

Saving as a Tiff with no compression and layers included will produce a document that works with Unity.
