請問怎樣才可令到玻璃的影子有焦散的效果? >.<" 研究了很久也做不到....

it depends on which renderer you are using.

MENTAL RAY

[sobig]

To create refractive caustics,

use the refractive objects' Object Properties dialog > mental ray rollout to have the object generate caustics.

Adjust caustic settings on the Render Scene dialog > Indirect Illumination panel > Caustics And Global Illumination rollout.

Setting an explicit Maximum Sampling Radius value can help improve quality, as can increasing the number of caustic photons.

Or, go to user references> search"Creating Refractive Caustics"
there is a detail tutorial about this.
