Single layer (8 bit) png alphamaps

Hello,
Seems to me the 8 bit png alphamaps do not store the data in the alpha channel. When I load these in DX Texture Utility the alpha channel is empty.

So in the meantime, I manually convert them and save them as .DDS and then my program can use them fine.

Is there any option / plan to make it so you can select whether or not to use the alpha channel of hte png with single layer alpha maps?

Thanks,
-Mike

Hi Mike,

The image library I use (FreeImage) doesn't support 8-bit alpha-channel-only images. The closest I can do is an RGBA image with only the alpha channel used. Would this suffice?

Cheers,
Aaron.
