How to color/tint a single section of a texture atlas

Hi Everyone,

I'm experimenting by adding textures to cube faces. I'm using one Texture Atlas and then choosing a tile at run time to add to the face of the cube. So far this all works as expected, but now I want to be able to tint or color one of the tiles differently than all the others, but can't figure out how to do it. I have figured out how to color a full texture, but not just one tile.

I'm currently using a texture atlas that does contain some transparency in it - just in case that makes a difference.

Thanks in advance!

 

How are you choosing a tile? Do you have a different material on each face, or are you modifying the UVs of the mesh itself? If it's different materials then you can just have a time l tint built into the material. If you're modifying the meshs UVs then you might want to just modify the vertex colors.

 

I have one texture and proceduraly creating a mesh one object at a time, then assigning the UV coords for the tile to each face. I thought modifying the vertex colors would just "override" the texture tile being applied? Would I need to incorporate a custom shader to get the affect I am looking for?

I'm just wanting to color certain white texture tiles to make them the color of the sky, dirt, grass, etc.

Thanks.

 

Like @bgolus said. In this case I think you can only use vertex paint to get the result.
It won't override the texture. White vector color = Your original texture color.
Other vertex colors blend into that colors by using multiply method.

 

Yes, that was what I was looking for. Thank you both.
