lens flare from lightness

	Re: lens flare from lightness by Jeremy Fabiano on Sep 13, 2009 at 5:08:52 pm I'm not entirely sure exactly what you're after, but you can link the lensflare position & centerpoint to the dot's position & centerpoint. Or you can set the flares position somewhere (center perhaps?) and have the centerpoint follow the dot.. I hope this helps, if not, post more details and we'll try to help. -Jeremy Respond to this post   •   Return to posts index

	Re: lens flare from lightness by Kevin Camp on Sep 14, 2009 at 12:28:54 pm to link the flare's center point to the dot layer's position, you'll use an expression. select the dot layer and hit 'p' to reveal its position property. then select the lens flare's center point property in the timeline and choose animation>add expression. click that expression's pickwhip and drag it to the position property of the dot layer. this will link the flare's center position to the layer's and it should now track it.

	Re: lens flare from lightness by Ben Heusner on Sep 15, 2009 at 5:16:05 am Dan Ebberts has an awesome expression that also lets you link brightness to Z position to save you from keyframing brightness. Apply this to Flare Intensity: INTENSITY l = thisComp.layer("YOUR DOT LAYER"); r = (l.transform.scale[0]/100)*(l.transform.scale[0]/100); s = value*r; c = thisComp.activeCamera; p = l.toWorld(l.anchorPoint); f = c.cameraOption.zoom; dist = p - c.toWorld([0,0,0]); vec = c.toWorldVec([0,0,1]); dist = dot(dist, vec); s * f / dist; You should link the Flare Center to the layer's anchor point.
