Hey there,

I'm trying to create 32bit BMPs with alpha channel. Re-Volt doesn't seem to recognize them (doesn't load them entirely). I tried with both, Photoshop 13 and GIMP 2.8.

I made sure I ticked alpha channel and saved them as 32 bit. I tried X8 R8 G8 B8 and A8 R8 G8 B8.
Urne's 32bit Bitmap-pack works for me, so Re-Volt is not the issue.

Any clue?
Thanks in advance. Have a nice day!

- Marv

Uploading an example of a broken BMP would help investigation...

Sorry, I forgot that.
I didn't know that PNG's and BMP's alpha channel behave different.
I'm writing a tutorial for Photoshop right now.

Done:

A tutorial for gimp is coming as well.
