dynamic lighting

As the picture shows I am trying to use the circle for dynamic lighting. First it doesn't actually make a circle it makes a weird square and then it also for some reason has a big opening in the bottom left quadrant allows light through and doesn't stop tokens with movement restriction on. I have tried multiple times and keep getting the same results. Is this an error or is dynamic lighting circle not really a circle? Also the movement restriction follows the square shape as well and not the circle drawn?

Circles don't play well with dynamic lighting (and are processor intensive). Try using the polygon / line tool instead.

Brian is correct. From the wiki entry on Dynamic Lighting . Note:  Presently, circles drawn with the Circle Tool do not render light blocking correctly. Instead of using circles, create a rounded shape with the Polygon Tool. You can find some good hints and tips there and at the  Dynamic Lighting Style Guide . Since this is not actually a bug, I'm going to close this thread, but feel free to open another if you run into any further problems.
