I only find set scalar/vector/texture parameter nodes in blueprints,but I cannot find comething like setboolparameter in blueprint…So How can I change staticSwitchparameter material nodes in blueprints during runtime?Thanks!
StaticSwitchParameters cannot be changed after the shader has been compiled (hence the static).
For a dynamic switch you should use the If node together with a scalar parameter.
Compile two different version of that material and dynamically swap between them.
