What is the idea of this?Please help me, thanks!
You will have to use a custom shader for that, where you pass a custom uniform that sets the border between the two colors.
This can be quite advanced if you aren’t fluent in GLSL. A good place to start are the shader tutorials here:
Thank you for your answer. Yes, I know that materials must be customized, but what’s the idea of changing colors?
You use a shader to apply two different colors in your material, based on a custom uniform (param) passed that defines the current border per frame.
@Leonidas is right, you need a custom shader for this. The shader itself can be pretty simple, I made an example here:
Many thanks for sharing this @LeXXik!
This seems to be good,too
