How can I change color of my material inside a "material builder" network, over time?

[Masoud]

Hell;

In my "material builder" network, I would like to change color of my material (base color), over time.

When I add a ''Principled Shader" outside of "material builder" network, it works fine but inside "material builder" network it doesn't...

How can I fix this?

(I think Houdini compiles "material builder" just once )

Thanks.

You need a parameter for this.

MaterialChange_fix.hipnc

Yes, always when you have a time dependent parameter, never animate keyframes or add expressions inside the VOPnet iteself.

Always promote the parm and do it on the outside.
