Texture transition from center of circle outward

Support Materials and Textures

Hello.

I want animate my ground texture to transition from alive to dead grass. Right now this is a base texture not a particle system.

My vision is to have a missle come in from a above and hit a spot on the ground (i have that)

Then I envision having the grass change from a green grassy texture to a brown grassy texture. But I want the transition to radiate outward from an interior center point of a circle to the outer edges of the circle. I can transition from, say, the left side of the circle to the right, but I can’t figure out how to do it radiating from center of circle to outer.

I couldn’t find anything online or a video description of it. So if anyone knows how this might be accomplished or if you know of some video I can follow, it would be much appreciated.

Thank you!

Use a Gradient texture node, change it to Spherical. Use a mapping node to move the center point- change the mapping to Texture, the X and Y to 0.5, and scale as needed

Hello. Thanks for the help. I got further. I can have it transition like I want if it is just the color ramp, but when I use the color ramp as the factor into a MixRGB to transition between the two textures, nothing happens

What else may I be doing wrong?

This image is roughly what I want to happen (and when I animate the color ramp it transitions like I want)

And this image shows the node settings for that.

However when I try to plug in the two textures I want to use like this, using the color ramp as factor.

I get the image here: a solid grass image.

It is really probably something simple, but any help would be appreciated.

Thank you! :smiley:

Your color ramp should be black and white only- black will give you grass, white will give you dead grass

Thank you. So, yep. It was something simple.
