The HUD works, yes.
What I meant was those wearable alphas that come with some mesh clothes. Like, you get a t-shirt and an alpha that hides the parts of the body under the t-shirt. This has always worked with the system body, and it also works with the Roth2 v2 BoM-enabled mesh body (yes, it hides the actual mesh body). It does not work with Adonis 4, though.
