Hi,

I've got a little problem with a render and i don't know how to solve it.

To summarize a bit my problem,

I've got a 3D object with reflection and when i'm done with all the lights, shaders,... parameters i've got this kind of result (in red)  
Can someone tell me what i've to do to get a proper (or something better than my stair result) reflect!

Thanks,

It looks as if you're using a depthmap shadow with the stair stepping... try upping the resolution on your depthmap then or you could give it a blur.

If it's not a shadow, then simply up the ammount of samples per pixel in your render settings.
