I have only PSP 9.
- create a new mask layer
- paint your alpha channel in the mask layer
- Menu "Layer"->"mask save/load"->"save mask in alpha channel"
- Menu "File"->"export copy as..."
- export options: choose 24bit as color depth
Yeah I did that all that, But in MED in texture options it keeps
saying it's only 24bit. Even when I choose 32bit then select alpha the transpareny still doesn't work properly.
But with png format it works as it should. Hmmph, Go figure.
So rather than waste time trying to get TGA working properly it's easier and quicker to just save as png.
Thanks everybody for your input though.
