Hello
I am working on landscape and i am scattering the grass, in order to break up the grass color for realstic view i want to make a different approach if possible of course, Is it possible on shader editor to draw a texture with different color variation and to tell the blender on white area change the saturation a little bit or value like in this way.
I want to create a vegetation scattering system where the scattered objects (grass, trees, bushes, etc.) keep their original textures, but their appearance can be influenced by the surface they are scattered on.
For example:
The vegetation models already have their own texture maps, and I do not want to bake anything.
The goal is to have instant variation: if one part of the terrain mask is white, the grass or trees scattered there should automatically receive a different color variation, while areas that are black keep the original texture.
Basically, I want the surface texture/mask to control variations of the scattered objects through Geometry Nodes and the material shader.
It depends on how you are scattering them, but you probably want to pass some attribute from geometry nodes to the instances and then edit the textures of them in their materials. You can make a single group that would contain all the edits so it can be easily repeated in many materials. You would then use the attribute to change properties of the instances that have it in their materials:
scatter.blend (1.8 MB)
Yes. You can do exactly the same in your scene.
If you dont mind can you just tell me where to put these nodes in geometry node because when you scatter on surface there are lot of nodes where do i need to put them exactly
At the end of the scattering geometry nodes tree or you can even make a new geometry nodes modifier just for adding the attributes that would be placed after the one scattering. The scatter modifier makes instances, so they are there and the idea is just to add attributes to them.
Thank you so much
I just want to add one more question is it possible to make the instances to get the color where they sit, example if instances sits on red color of plane than it will be solid red if it sits on blue side it will be blue very much like particles but instead of particles this time it needs to be with geometry node
The earlier version that you told me i have tried and it worked perfectly fine as in first image showen but this time i want if it is possible to work exatly same as hair particles you can see the plane has the texture and hair particles gets the color where they sit so it creates different variations like you told me eariler you create a mask and than you play with hue saturation, i want my scattered object have no color but it gets them from plane where it sits, i hope i am clearer now 
Yes, solutions tend to not work when you ignore them. 
I will not be able to help with that. It’s in the file I shared though…
