I have made a video that is in a 3D effect. I have a logo and a light source shining on it. I have got a shadow coming off the logo but the edges of this shadow are too sharp. I want to soften the shadow. How can edit this shadow that hasn't been created from a shadow effect?
Adjust the shadow map size on the advanced comp settings. Otherwise you need to work with duplicate comps and use the Shadow only option on the light, so you can blur it and comp the result as a 2D layer.
I think I've found the fastest way. Within the light setting itself you can edit the Shadow Darkness and Shadow Diffusion.
