I want to know how can I cast a shadow of a tree to my render. If I use a speed tree in front of the light, will it cast shadow to the objects? Or should I place a 3D tree model? Or else should I place a plane with tree texture?\

Which one would be better?

    $\begingroup$ I'm not sure I understand.. What's a "speed tree"? $\endgroup$ – gandalf3 Apr 26 '16 at 6:30
  • $\begingroup$ So I gather that SpeedTree is software for modeling plants... that's about all I know from 10 seconds of searching online. But if that software generates textures and UV maps it's just a matter of setting up those textures correctly with Cycles nodes. I'm inclined to think it should work. Why don't you give it a try? Sounds like you have a pretty specific workflow, so the best thing to do would be to test it out. $\endgroup$ – Mentalist Apr 26 '16 at 6:47
  • $\begingroup$ Also, as a general tip when dealing with lots of foliage: make sure your max transparency bounces are turned up high enough or you may encounter problems like this. $\endgroup$ – Mentalist Apr 26 '16 at 6:50
