Question about the off screen particle rendering.

Questions & Answers
1

Hi,

I am trying to show the smoke particles in low resolution texture and then blend back with other parts in the scene.
I read the article http://technology.blurst.com/off-screen-particle-optimization/ and make a simple test project in https://docs.google.com/open?id=0B1nYEeuWnX0DVHRaaS1uMG1EXzA

But unfortunately, the alpha transparent of particle textures seem not working correctly, they are just showing black.
Anyone can help me how to correct this?

Thank you.
