Hey guys,

I was wondering if anyone has or knows a way to get the Superman minifig on LDD with the symbol on his torso? Thanks.

There are 2 ways, one way that breaks the LDD EULA and another way that I don't know how to do.

...so for all practical purposes the answer is simply: You can't.

But you can try Ldraw - there you can change/apply decorations.

LDD2Powray allow to add custom decorations.

If your aim is to create a rendered image, LDD2 PowRay could be a good solution.
