Does IRRLICHT support normal maps?

Hi, I don't know if IRRLICHT support this. If this does, this could give us incredible details. But I thing this need shaders to work...

Anybody know?

That's basically what the NormalMapRenderer are thought for, I guess

Wow, it's there?!!

Is there a tutorial where I could refer to?

I would really want to use this. (For me more than wanting...

)
I'll want to create crazy detailed model (1 millions poly and more), then bake it under a normal map to a low rez model. All newer render pipelines for games engine support this (As in DUNIA (Far Cry 2 engine from UBISOFT that i've been demonstrated this week. For me that engine will be superior of the Crytek one used in Crysis)

I'll create the basic meshes in Lightwave, then do the crazy detail in MUDBOX. I never saw informations on how to use a normal MAP in IRRlicht. In the long term, If im good enough, I would produce a look like in ASSASIN's CREED. For a new demo (Planned in december/january).

Please, if someone could give me some infos on how to apply a normal map in IRRLICHT, I would appreciate it very much! I didnt saw info about this so far.

By the way, I asked lots of questions on DUNIA and could I post a report on the forum somewhere? Some Irrlicht users have done some things that we could use in the long term to go in the same direction...

um, haven't you been reading the irrlicht docs and checking out the examples?

there's a tutorial here: http://irrlicht.sourceforge.net/tut011.html

feel free to post anything you like, I guess.
anything which might help improve Irrlicht, or help us users make better applications using it, would be heartily appreciated

Wow! I was only thinking that tutorial was about Bump mapping things.

I'll check this in details. Thanks for pointing me this out!

Guys! With this I'll think I'll create some incredibly detailed model in the next few months! I'm exited now!

Just to see how to create normal directly from Lightwave (Baking Camera, but I'll need to check the detail). I'll need to map the increased details in this normal map texture on a low res model, and would have visually about 80% of the Hires look.

Yes, that has been done before. Check the project announcements or Code Snippets.
Please note that there had been problems with normal maps on animated meshes. Now that the new animation system has been integrated the situation might differ, but probably no one tested it, yet.

For animated meshes this looks good:
