ugly shadow texture

[kwok3d]

check shadow areas


check shadow edge on sphere (no bump map applied)


check shadow edge on sphere (bump map applied)


1st: irradiance map 1.0
2st qmc 0.5
adaptive -1/2 catmull
preset: high (weighted ave/density-base)

anyone know why?

ahh have you tried ticking "smooth surface shadows" on your lights?

[kwok3d]

yes

yes. i do have it on.

On the sunlight (vray shadow):
Transparent shadows = off
Smooth surface shadows: on (Bias0.2)
Area shadow = on
Subdivs = 8

in fact, the shadow on the sphere is ok since there won't be bricks on round obj. but the shadow area with blurry bump texture is bugging me. i hope someone has a solution. thank you.

Decrease the Threshold for the Adaptive subdivision AA and it should be fine (the texture in the shadow, I mean).
