As the title above. I am trying to sampling direct light and indirect light. But I have many transparent objects in scene, it's very likely to block the testing ray. To my understanding, it's not good to give up the testing ray if the blocking object is transparent. Because it still have very large chance to hit light source after coming out from transparent object. But I don't know what exactly should I do to make it correct and unbiased.
So, what is the best practice for direct light and transparent object?
