I have a question regarding photoshop for anyone that has knowledge to help.

Basically, im trying to create an alpha mask around my texture so that the surrounding white box becomes transparent.


I have already made my alpha channel, and whited out the area that I I want 100% opaque.


I have tried saving the dds as

DXT3 ARGB 8 bpp | explicit alpha
and
DXT5 ARGB 8bpp | interpolated alpha


But the white boundary that I have tried to cover up in my alpha are still visible.


Any thoughts?

If you open the DDS file again, is the alpha channel still in the file and still the same thing?

If yes, you are probably trying to use it on something that does not have the alpha property thing and you will have to add it with nifskope.

If no, then something is wrong with your dds export, so post a screenshot of your export settings?

If I open up the dds file after saving it, my alpha is still there, but it is hidden, and I still see the white border that I covered up

Then you have to add an alpha property node to the mesh, you open it in nifskope and right click anywhere and select these:

Then, in the nitrishape node you set "property link 2" to the number of the newly created alpha property.

That is if you are using it on a mesh. I just kind of assumed you are. If not then can you specify where you are using it?

it is the world map texture

Where do you see property link 2?

and what if there are 2 nitrishapedata?

When I add the nialphaproperty to the nitrishape in nifskope, my texture in game becomes invisible
