Irrlicht Engine

Hi guys!

I'm new to Irrlicht (actually I'm using Irrlicht.Net) and I came across a problem with making a model transparent. I add 3ds textured model, a camera and one or several lights to the scene: everything renders fine. But when I change material type for that model to TRANSPARENT_VERTEX_ALPHA the model is rendered incorrectly: far faces are sometimes rendered on top of nearer ones. It looks like no alpa-sorting is performed.
What shall I do to get a single model rendered correctly with transparency?

May by you can't setting correct flags for material,
try put true on these material flags:

ZwriteEnable
ZBuffer
BackFaceCulling

that makes zorder work, but another thing is needed to use TransparentVertexAlpha:

when you create mesh you have to set the alpha value of vertex color less than 1.0 to get some transparency

Thanks for advice, but it didn't work.

TRANSPARENT_VERTEX_ALPHA doesn't work properly with any combination of material flags (zbuffer, zwritesenabled, backfaceculling, lighting, and all others). I spent two days playing with all these options and material colors with no result.

I've managed to get transparent model by using TRANSPARENT_ADD_COLOR material type. It works fine but this option mixes material color with texture color and I need pure texture color. I guess, TRANSPARENT_VERTEX_ALPHA should do this but it doesn't work for me. So the question is still open: how can I render model with alpha but without material color blended to texture?

(I use Irrlicht 0.12 with DX9 driver on DirectX 9.0c from Aug 2005 DX SDK update.)

bump. help.

screenshots please. just because...

quickfix: use opengl not d3d

Flip normals

Normals have nothing to do with this problem

Just wanted to say something

Best not to if you don't know what you're talking about because you'll just confuse people... it's not a contest to see who can post most!

JP, you are not in the mood today?
My idea based on own experience.
Sometimes when exporting meshes in .x format i received very similar problems with incorrect polygon placement, but it was only visual illusion because of incorrect normal directions.

Normals are only used for lighting so they're not going to affect z-order at all.
