Transparent Shader Problem

Hello,

I’m trying many different transparent shaders for my imported trees with varying levels of success. I am targeting mobile. The problem I am having is the trees look ok close up but when camera gets further away the tree gets dark. I have also tried changing settings in the texture to no avail.

I know very little about writing shaders or even if it’s shader related.

Any advice would be greatly appreciated.

Thanks

I noticed if I turn off Mip Maps it completely removes the dark at a distance but from what I understand Mip Maps are faster. Any way to do this with Mip Maps on?
