Issues with the tint of the shader

[JovenOculto]

I know it is an old shader and possibly you no longer pay attention to this but I have not found a shader or similar anywhere on the internet and it is very necessary for my current project. the problem is that I have tried a thousand things but it always applies a greenish tint to the texture, any idea how to solve it?
This is the porblem

And this is what it should look like

the difference is small but crucial

Hi there! Glad you've found this useful. This is pretty old code but reading over it again I didn't see anything that jumped out to me as making the image greener. The reason that your sprite looks washed out is probably because this is a lit shader. If it were unlit it would look exactly like the input texture.

You could try modifying the shader to be unlit. This is the simplest approach to doing so:

Another approach would be to rewrite it as a vertex / fragment shader instead of a surface shader!

Thank you very much, I will try the options you tell me :)
