the distortion emitter doesn´t read the normal map in the particle section. The distortion keeps the form of a square. What i am doing wrong? I´ve just follow the tutorial in the manual. Plese, help me.

Which normal map you use?
Share it to me, I'll check it out for you.
And if you have some screenshot will be helpful!

Thank you. The problem was the driver of my video card. All working now.
