Transform Controls Broken?

[ManaforceStudios]

Hello! Was utilizing this in a project, and noticed that the geometry is locked to scaling with the container. I thought I'd be able to use the Set Ball Transform node to change the Scaling, as well as Location, but it seems that Transform is only affecting Location.

Do you know of a good fix for this? Am happy to pay to fix it up!

Can't be fixed. Metaballs are calculated and rendered inside fixed boundaries (grid).

Oh there is no way to be able to scale the boundary box so you have more room to play with?

You can try to scale the Actor or change grid size.

I've tried scaling the actor, but the geometry scales with it. I'm unsure of where to scale the gridsize though, so that's something I haven't tried yet.

Try to change MetaBallsBoundBox->InitBoxExtent(FVector(100, 100, 100)) to bigger values, like MetaBallsBoundBox->InitBoxExtent(FVector(300, 300, 300))

Okay, will do! Is there anyway to expose that parameter as an adjustable Scale?

Too long a time has passed. I'm not remember, just dig deep into the code and explore it.
