I need help with vertex colors

[median hound]

Why do you want to do it via Vertex?

I've couldn't find any other way if you know I'd like to hear.

Doing a quick google search I found this video that seems like what you want. I haven't watched it nor am I the best with shaders but the result looks good.

thanks for trying to help! but i don't think i can implement that, anyways do you know other ways to paint a mesh via code?

[median hound]

I can't really help if you don't elaborate why you can't implement that one or any details about your terrain generator. Here is another one in 2D

the reason is, i want to make the biome generation like in this video the other video you shown is only works in vertical and i need to Implement this video in 3D for the effect i want

[neat cypress]

is there really noway of doing the effect i want?

[median hound]

I am sure there is a way but I do not know what effect you want. I did not understand what you meant by "only works in vertical" and you seemed quick to dismiss these examples as helpful because they aren't exactly what you want so I do not know how to help.

Sometimes you need to start with something that isn't your ideal implementation as a jumping off point and then work towards what you want once you understand the code better.
