A broadcast production company faced challenges in creating a scalable virtual set for live streaming events. The primary objective was to design a visually striking and dynamic virtual set while maintaining optimal performance across different hardware configurations. To achieve this, the team utilized Wasp3D’s tools and followed industry best practices for 3D modeling.

Process

1. Unit Scale Validation
   The team ensured their 3D models adhered to Wasp3D’s unit scale of 1 unit = 1 centimeter. This step was essential to avoid alignment issues within the Wasp3D Designer environment. Proper scaling also ensured consistency during the import process and maintained accurate proportions.
2. Poly Count Optimization
   To balance visual fidelity and performance, the poly count was tailored to the hardware specifications. High-poly meshes were reserved for objects close to the camera, while low-poly meshes were used for static elements like walls. This approach allowed seamless rendering without straining system resources.
3. Transparent Object Handling
   Transparent or semi-transparent objects like glass were excluded from the baking process, as baked textures cannot replicate transparency. Instead, their materials were applied directly in Wasp3D Designer. This ensured that glass elements retained their visual properties, such as reflection and transparency, without complicating the baking workflow.
4. Reducing Object Count
   Complex elements like trusses, lights, and furniture were consolidated into single meshes wherever possible. Screens, glass, and other elements requiring unique material properties were kept separate to allow individual controls. By limiting the total object count to 20–40, the team minimized rendering overhead and maintained a streamlined workflow.
5. Efficient Material Assignment
   Screens and other reflective or emissive surfaces were handled with separate material properties, enabling fine-tuned adjustments in Wasp3D. This separation allowed for dynamic updates during live production.

Outcome
The resulting virtual set was optimized for mid-range to high-end systems, ensuring smooth performance during live broadcasts. Adherence to these guidelines enabled faster rendering times, reduced processing overhead, and enhanced visual quality. The production team successfully delivered a professional-grade virtual environment, meeting the demands of their live audience while staying within technical constraints.
