and gamedev as usual.

I'm not sure but I don't believe irrlicht has this yet but with that article and more experience then i currently have you'll be well on your way to making dreams come true.

Check out IrrCinema in the projects forum, that project has been playing around with HDR i believe.

To get an effect like real HDR, you'll need to do some big modifications to irrlicht. You will need to change the render targets to be 32-Bit and floating point. You will need to remake all your textures into floating point formats (I believe DDS can do this, not difficult to add in). You'd then have to write the shaders to calculate the effect itself.

Its a long a grueling task, you should stick to something simple, like bloom, if you are using irrlicht
