When developing complex systems in Unreal Engine 4.26, choosing where to draw the line between Blueprints and native C++ determines your application's stability and frame time. Feature Area Blueprint Best Use Case C++ Native Requirement State machine transitions, visual blending logic. Custom Control Rig units, complex IK solver algorithms. Niagara VFX Parameter updates, basic particle triggers. ; Place in DefaultEngine

When debugging shader code or custom render passes introduced via C++, use the RenderDoc plugin. You can capture a specific frame directly from the viewport by clicking the RenderDoc icon on the top right of the viewport window. Custom Control Rig units, complex IK solver algorithms
