Is it possible to export a *.png with RGBA8 in Photoshop?


Doing some design for 3D and developers need PNGs with RGBA8 for transparency. I am not even sure if this is possible with png. When I look at channels I see no alpha channel but there is alpha on the png, which is very confusing.

My flow is usually through generator, so I name layers fileName.png32 so it does full alpha but they turn out wrong and I have to open them and resave and that fixes it somehow (though I still cannot see alpha channel).

edit: more details. Here are the actual error I get from the program trying to import the PNG.

MakeImageCompatible: Converting Image 'item url here' from TEXFMT_BGR8 to TEXFMT_BGRA8

so its saying somehow it cannot read the alpha channel from what I gather.

Is it possible to export RGBA PNG from Photoshop? Very much so!

As Scott said, there's no separate “alpha” channel visible in “Channels” panel, but the alpha channel is there anyway (just not “shown” in the panel), as long as the image doesn't have the “Background” layer. Anyway this alpha channel is used when PNG files are saved. If you need some more control over your PNG files saved by Photoshop, I recommend you to use the “Save for Web”.
