Trees are created using Object Grass and Impostor material.  I need those trees keep color all visible distance. But they getting darker when they go further. How to fix it? Thank you

Hello osa,

I think this is caused by texture mipmaps. Please check the color of the low-resolution mips of this texture. You can do it in the Editor, just select albedo texture and use drop-down menu, I've attached a screenshot. If the color is going darker, you can do the following:

• Change the mipmapping type. I assume the blackened view was caused by point mipmaps. If I'm correct change it to box and check the result.
• Modify texture mips manually. If you can get the desired color just by switching mipmaps type this is the preferrable option.
• You also can use mip bias parameter to shift the distances. To do so enable Mip bias state in the material and configure its value in the parameters. This can can drain performance in some cases, so be careful.

Hi. You were right. The problem was with mip maps. The problem is that Impostor creates black background. I filled it with green color and it works now. Thak you.
