Terrain paint problem

Hi Guys,I want paint terrain with leaf but leaf texture have problem(I use PNG format) and I take this problem if anyone know this pls help me thx
Photo example:

 

and I used mip maps , It is worse )

 

What you're trying to do doesn't seem to be supported. At least not using the default shader provided for the terrain layer. You seem to have enabled the Alpha Is Transparency option, but the shader seems to ignore the alpha values of the texture (I assume for performance reasons).

 

I assume you're trying to paint fallen leaves on top of dirt? Unfortunately that's not how terrain painting works. It just blends the colour values of each of the textures together.

As @powersupersport says, the terrain shader doesn't support transparency. So it's just reading out the colour values, and ignoring the fact that some pixels aren't supposed to be visible.

 

I see some game there are on terrain leaf ,stone, garbage ,I think that of only 3d model I will try with 3d model thx for help guys good game good works

 

It can be models, decals, quads with textures on them... a custom shader with a leaf layer built in...

Think about it this way. Making a terrain is just a specialised way of making a 3D model. You're applying a texture directly to that model, where it seems (from the texture) that you want a separate texture shown on top of that 3D model.

As a first pass approach, try this:
1. GameObject -> 3D Object -> Quad
2. Drag your leaf texture onto that quad in the scene
3. Change the Quad's material's Rendering Mode from "Opaque" to "Transparent"
4. Copy, past and move as desired.

This is a very simplistic approach, and may not perform well at scale depending on your use case, but hopefully that'll get you started.
