Photoshop alpha channel


Recommended Posts

In photoshop there is a tab beside the layers tab, that allows you to add a shaded alpha channel to a .dds file.

I need to add a black alpha channel to a .dds file.

I've tried every alpha pluggin I can find but cannot replicate this effect.

And if I open a .dds file created in photoshop with a black alpha channel it is completely invisible in paint.net.

Why is it completely invisible in paint.net but not in photoshop??

How can I add a black alpha channel to a .dds file in paint.net????

You can make and alpha mask and use that like an alpha channel...you just wouldn't be able to edit it after you apply the mask

No, Paint.NET is not spyware...but, installing it is an IQ test. ~BoltBait

Perhaps 'Alpha mask' could be added to the layer blend options?

Just applying the transparency of one layer to the layer below - ignoring colour values?

It would save time having to use the (brilliant) plugin and the magic wand doesn't seem to copy transparency.

Paint.NET combines the file's alpha channel with the source image, if the source image has a completely black alpha no image will be visible when loaded.

Importing a black image with one of the alpha mask import plugins should work.

The small increase in performance you get coding in C++ over C# is hardly enough to offset the headache of coding in the C++ language. ~BoltBait
