Hi,

is it possible to map a ramp to a depth map shadow so the 0 value of the ramp is in the border and the 1 value of the ramp is in the center of the casted shadow ????

thanks a lot

I think there is NO way...thats the reason we all use soft shadows...that's what you want,isn't it???

What I realy would like to do is to fake caustics by colorizing a shadow map with a ramp... but I think the easiest way is to bake the light on the texture and to do it in Photoshop... but I have to exclude to animate the caustic effect

I thought it was possible to find the center and the border of a shadow with a light utility or some mel...

thanks anyway
