Why is it so hard to control the mapping of color ramp?

Hi, I would like to create a gradient of colors that looks like those cute little cheeks :smile:

I find it very hard to control the mapping. I’ve been playing with the parameters for more than an hour but I can’t make a simple circle-like gradient. I’m sure that I’m missing something. Why isn’t it easy like photoshop or other software? Here’s my node setup:

if you use a sphere you can do it like this :

Did you try a different mapping than the default “linear” ? :slight_smile:

Thank you so much for your suggestion. Actually, I’m not using a sphere. I would like to color a cheek of a simple character. So I select the faces that form the cheek and then I assigned the material to them.
Can I use your method and apply it for a cheek or non-uniform surface? Or does it work for spheres only?

For a plain face you need another setup

Actually, yes :slight_smile: Nothing worked

Thank you so much :smiley: I’ll try it and I’ll get back to you as soon as possible.

or you can use maybe vertex weight

For the second method you gave me (the plane method), it gave closer results when I unwrapped the UV and connected the UV output of the Texture Coordinate to the vector of the Gradient texture.

OMG I didn’t know that there’s a vertex weight option. I’ve just googled it and it seems that it’s a much easier method. I’ll study it and I’m sure that there’s a great probability that it’ll work. Thanks again for your suggestions. You’re great!
