Setting transparency on to an instanced object with a partially transparent texture does not have the desired effect.
It seems that the fully transparent parts work ok but the parts with partial transparency show through to the background UNLESS there is another object between them.
You will need an image with partial transparency to run the code. Click the download button to use the one that I have used.
