how can i soften the object’s shadows the lamp lihgt casts because they are very sharp.I read about a radiosity method but it’s complicated and if you change the camera’s position it’s useless(if an animation).what’s the solution?Can yafray do better?
Do you have to use a Lamp?
If not, try an Area Lamp. Turn on Ray Shadow and set the samples to about 12. Higher numbers = softer shadow but slower render.
Or you could use a Spot light with Shadow Buffer. Adjust Soft, Bias, and Samples in the shadow spot panel to affect cast shadow. More samples = better shadows but longer render time.
