Maya; HELP: Transparency Map works bad

exoddinary

Hi there,

This is my character I did for my game (refer attachment). At first I tried making all model with 1 texture map (1024x1024), and having the hair with some alpha map. I discovered that it creates a weird invisible texture anywhere I toggle my camera.

Then someone said I have to create a transparency map for the hair, but it still result the same. Help me!

Picture 1 - With transparency map
Picture 2 - With no transparency map (notice the white layer with the hair)

Try setting your Viewport 2.0 render settings' transparency algorithm (under Performance section) to Depth Peeling.

Can't. Maya LT doesnt have that feature.

I just notice a thread somewhere else having this problem by accidentally activating a 'transparency' map HERE .

While the one who posted that issue was trying to eliminate transparency, I'm trying to achieve that, and its important for many of my assets..

Anyone?

What does it look like in the target engine? Unless Maya is the final stop you'll want to preview it in an actual engine.

This is a common problem with alpha blend.

There are some hacks though to help you solve it. In your case, it's fairly straightforward.

Set the hair model to be 1-sided. Duplicate the hair model, and flip its normals. Then attach the original unflipped hair model to the new flipped one.

This will force the outer faces to be drawn after the inside ones. This is mentioned in the wiki too.

This hack will allow it to work properly in any game engine too., as it's not dependent on Maya's depth peeling.
