Hello again,
I'm having some problems using transparency, shown on the following image. As you can see, the skybox is been drawn over the map, even if the sky is quite far. Also some of the map's walls are a little transparent (but not all). My code is configured to only use OpenGL.
Only two of them have the setTransparency(int) set to some value (currently 2) which I've not yet understood it's logic. Those objects are (in the picture) one of the skyboxes (the lowest one) and the map. The same objects have at least one of their textures loaded with alpha information (giving the flag true to the Texture constructor). Finally, I'm not using any kind of sorting information (and collision detection) like octrees and portals (the last one I don't even know how to use).
I've read of Config.glTransparencyMul and glTransparencyOffset but don't know how to apply them here. So, I really need some help here... Is it caused by missing sorting information?
PS: Im my opinion, there's missing some documentation on how to use transparency, portals and more. One solution could be adding a 'User tutorials' section on the forum.
