You mean like the TilesetWithOverlay7.shader example for 7 property block from _OverlayTex?
See Thread: https://forum.infinity-code.com/viewtopic.php?id=2185
In my case I have an unknown amount of textures which I need to placed as an overlay over those tiles (Lon, Lat) as it already works with this examples you provided?
I hope this makes it clearer. Thanks again for all your help.
]]>I was just wondering what you meant with "The second example that uses shaders is actually for a single texture, but this can be modified for multiple textures."
A. To directly modifiy the shader for multiple textures?
or
B. Modify the script to user multiple textures with the shader?
And is there an example for that?
Many thanks!

}P.S. I haven't tested this change in the shader, but it's very likely to work.
]]>With those examples I am not able to change the colors at the moment, but the alpha update works.
I have tried with TilesetWithOverlay.shader and TilesetWithOverlay2.shader:
tilesetOverlay.material.SetColor("_Color", color);
tilesetOverlay.material.SetColor("_OverlayColor", color);
Any suggestions?

The second example that uses shaders is actually for a single texture, but this can be modified for multiple textures.
]]>I am not sure if there is an example or solution for this requirements.
1. We need to load multiple images and overlay those images over tiles (1 degree long and lat).
2. Those need to also zoom in and out accordingly when we zoom the map in and out.
3. And finally we need be able to change color and fade the alpha value as well.
Is all this possible?
Thanks again!
