The statement "lens flares can not be produced in Bryce" is not accurate...and it does not require the imagemap and mask routine.. however achieving it is not simple, nor is it as convincing as the effect you can get by just taking it into a third party image program... and doing this also increases render time... but if you are dead set to do it in Bryce, here is how to do it: 1> create a standard tube and apply a shiny metal material to it 2> create a back for the tube (this can either be done by just making the inner cylinder shorter than the outer, or by creating a new cylinder and putting it at the back) 3> create a "lens" by creating a large positive sphere, and one smaller negative sphere and one negative cube. Align the objects so that the small sphere cuts out the inside of the larger sphere and then put the cube in such a way that it will cut off the majority of the larger sphere...when you group these, you will have a "lens" like object. Apply a glass material and put this object in the front of the tube you made earlier. 4> Put the dolly camera inside this object that you created...you will now need to put a spotlight behind the camera (within the tube) and one in front of the camera (where ever the light is coming from) this will mimick a lens flare..and it does work, however since you are rendering from within an object and the camera is rendering its pov thru a glass lens, the render time will greatly increase depending on the scene you create. I suggest you play with this method if you are dead set in doing it straight out of bryce... good luck BT http://www.brycetech.com/
