Transparent geometry

Hey, I’m trying to create a transparent geometry so I tried with this:

[java]geometryMaterial.setColor(“m_Color”, new ColorRGBA(0f, 0f, 0f, 0f));[/java]

But the alpha value seems not to change anything. How can I do that ?

The transparency section shows the methods used, perhaps thats what you require.

Yes thank you, I missed the blendmode and the facecullmode.
