Which parameter affects how soft the edges of the shadow are? Range=0.01 to 50.0

• A. Shadow bias
• B. Sample range
• C. Size
• D. Density

Answer: (B)

Soft edges come from how many samples the renderer uses to determine where light is blocked. The sample range controls how far those samples spread around the shadow, so increasing it adds more samples and creates a smoother, feathered transition at the edge. That range, from 0.01 to 50.0, directly tunes how soft the shadow edge appears. Shadow bias shifts the shadow to prevent self-shadow artifacts and doesn’t change edge blur. Size changes the light’s effective size, which can influence penumbra indirectly, but the parameter that directly affects edge softness here is the sample range. Density affects how dark the shadow is rather than how soft its edge looks.
