I'm currently trying to learn how to make these gears but whenever I try to color the said accessories on photoshop, they appear to be transparent in-game? How do you fix this?
In photoshop. It's on the same window as the layers, it's just a different tab. There are RGB, red, green, and blue channels and there should be a last channel called "alpha".
If the alpha channel is not there, do what damonrulz said. Save it as a dds and then reopen it to edit the alpha channel. You can create the alpha channel yourself, but the dds plugin doesn't like that sometimes.
Hey, I found my alpha channel. The window was hidden so I enabled it. I created an alpha and colored it white as you said. But it still turned out the same? T_T
