Hi, I have a transform matrix (4x4 → composed from 3x3 Rotation matrix and a 3x1 Translation vector) received from TCP connection.
How can apply this matrix to an actor?
Use SetActorTransform or SetActorRelativeTransform depending on your needs. I attach the links to the documentation. The parameter of type FTransform can be built from a matrix, or separate from Translation and Rotation (and Scale) in your case.
