Hi @Ace_Rothstein ,
there are no directly api for such effects but...
you can set color of modelItem Widgets and set the Opacity property - where you can change the color of the e.g. modelItem widget and make it transparent . So you use some script which will change the property in a loop / time interval so that to have the effect of continuous change
Another way /more advance /is to use some shaders [ developed in glsl] via the shader and texture property
e.g. in the post "Flashing effect of model item"
