Texture blur with distance, MIP not working correctly. Any solution?

Hi, I found that the textures blur poorly in distance. I think its a MIP problem, havent had this issue in any other 3D app, seems a trivial thing but it becomes a real problem in some scenarios. The wrong apha MIP make the trees look much heavier than they should, I have played with all the MIP settings but even in the sharpen 10 the problem remain. Changing the bias result in a heavy aliashing. Change the scale of the mesh on import, and change the texture streaming but no chage.

This is causing heavy issues when trying to achive diferent artistic styles. Any help will be appreciated.

bump!!!

bump, need to know how to solve it

There is Opacity Mask Clip value material setting. it defaults to 0.33 but you could bump it up a bit higher or lower to get expected look for masked materials at distance.
