Get animated color while shader is changing it?

Hi,

I've been trying to find a way to have the same color across objects from a material with an animated shader. This shader takes a color input and cycles its hue.
Using GetColor only gets the starting color and not the animated output color as the hue shifts.

I haven't been able to find a solution and any help is greatly appreciated.

 

GetColor only gets the color value you originally set on the material. The work the shader does to animate the color only happens on the GPU, and the CPU / script side of things have no knowledge of those changes. You’ll have to replicate the same hue modifications the shader is doing in your script.

The Color class has RGBtoHSV and HSVtoRGB functions which should make that easier. Assuming you’re using the _Time.y in the shader to animate the color, then Time.timeSinceLevelLoad, or use Shader.GetGlobalVector(“_Time”) to get the time the shader uses.

Thank you for the reply! I didn't expect syncing color to be this complex.
Right now I have multiple materials/shaders doing the RGBtoHSV, then hue shift, then back to HSVtoRGB calculations which I imagine isn't great for performance. Sounds like in the future I should do the calculations once via a script and then pass the resulting color to the shader via a global parameter.
It's also great to know that there are other ways of syncing shader happenings. Thanks again for the help!
