easy as pie! just like when you use any special effect with firefly, it uses a blender method of creating the effect, or splatter method (whichever explains it better for you!) what you need to do is tell firefly that you would like it to look at all the pixels around the area, and change the colour appropriately! how is this done you say? easy and sloooooooowly! under your ADVANCED render settings you will notice a nice slider bar called Pixel Samples. the number set within this slider determines how many pixels AROUND the pixel that is currently being rendered firefly will look at before deciding the end colour of the pixel it is working on! WHAT THE??? simply put, if you want less grainy effects (gather, DOF, ray-trace sharp shadows) you need to increase the pixel samples so that the pixels that have not had the effect placed on them (due to the grain method) will be effected by enough of the pixels that HAVE had the effect on them. ok that wasnt too simple.... poser sets it to 3 as default and ups it to 5 on production quality. For effects such as these, set it to 8-12 or higher if your computer can handle it. the higher you set it, the smoother the image will appear, but set it too high, and you will lose detail! hope this is not only understandable, but most importantly helpful LOL
