In fact, this bug is still there whatever old version of Corona or Corona v7.
To explain the BIG bug:
When you use a texture with alpha channel and assign to geometry, for example to leaves, and whatever you choose "CoronaMtl" or "Standard" material shader, you connected the texture with alpha to them "Opactiy", you will see the both still there alpha masked area and out alpha color and when you render, you will see the WHOLE Geomery just with a texture, no alpha masked effects or got reverse effects that the main content be masked and leave those should be masked content visible.
For example setting:
1.To create a "CoronaMtl"
2.To create two "Bitmap" nodes
3.To connect a "Bitmap" node without alpha to "CoronaMtl" Diffuse-->Color
4.To connect other "Bitmap" node with alpha to "CoronaMtl" Opactiy-->Color
5.Assign "CoronaMtl" to your geomery
6.Render it, and you will see that bug
3dsMax version: 2014
That's so affliction, this bug directly affect the forest, grass, flowers and them use a texture with alpha to create those leaves actually.
So, please please please please please please please please!!!!!!!!!!!!!!!!!!!!!!!

I think many have found the same issue in every version of Corona.
You have to put the opacity map inside a corona wrapper. It`s been mentioned before although I`m not sure if it`s considered a bug or not. It is however, a bit of a pain.
Apologies if it`s since been amended.

Hi, I tied to do with lots of way, but I found there is only way to get right render, you have to save out only alpha channel to jpg and put the alpha jpg to opacity, you will got right render. And about others pictures with alpha inside, all no way.
