Background Seeps Around Edges

[SpiderPig]

What would cause the background to seep through the leaves?  I've attached the two materials of the trees.

PineTreeLeaves.mat

PineTreeTrunk.mat

I've never seen this. Is it in AMD card? What is the MSAA level set at?

[SpiderPig]

I have GTX 980 TI.  Checking drivers now.  MSAA was 4x, I turned it off and the problem disappeared.  Nvidia problem do you think?

Updated my driver from 397.64 to the latest 398.36 for w10 64 bit and it didn't fix it. ?

I do not see any vegetation shaders being used in these material files - does that mean you are hand placing these tree models into your scene and not using the vegetation tool? If you are using the vegetation tool available in the Terrain tool options, then I would recommend using vegetation shaders as well or you will get weird artifacts/shadows.

Also, zsort on the leaves' material is enabled - that will affects the shadows that occur on the leaves and maybe related to what you are seeing here? Also you are not using a shadow shader for the leaves' material.

Typical pine leaf material for a model that will be used with the vegetation tool:

Thanks macklebee, turning off z-sort fixed it.  I am placing the trees manually as I've got my own terrain generator.
