Opacity masks for Unity.

[dominique120]

In 3ds max I have opacity masks like these:

On:

Off:

When I import my FBX into Unity I get the textures without their masks. Is there a way for me to do this in Unity?

You do this by first exporting a colour texture from PS or GIMP with alpha transparency (by applying your mask probably), then use one the KSP/Alpha/Translucent material in Unity.

I did not really understand this, could you explain it a little better please? Also, is there no way of doing this right in Unity?

don't use JPGs. it doesn't retain Alpha information. you need to use RGBA PNG or TGA.

If you want specific information then ask specific questions. What I said is exactly what you need to do. PS means Photoshop. GIMP is a free PS alternative.

I'm assuming you speak english and understand bit depth, and various image formats.

The only other thing I can think of is that you're used to a Max workflow where every texture has a separate file. In KSP the colour/diffuse map uses its alpha channel (if present) for specularity or transparency.

On my FusTek Station Parts, the warning stickers on the hatch doors are irregular in shape, so I use RGBA PNG textures for the sticker graphics themselves. In Unity, I then used the KSP/Alpha/Translucent shader to made the background region outside the stickers transparent.

You can see the results for yourself in the first and second screenshots below:
