Ensure all textures, materials, and maps are included in a single file to prevent missing resources during rendering.

Leverage Physically-Based Rendering (PBR) for realistic materials

Transmission for transparency effects.

Clearcoat for glossy finishes.

Volume for depth and density effects.

IoR (Index of Refraction) for refractive materials like glass.

Common texture maps: roughness, normal, thickness, and others.

If use Alpha Blending for Transparent materials, please use proper settings to render correctly alongside other objects

Check the depthWrite and depthTest to ensure objects render in the correct order relative to the camera.

Use double-sided materials for labels or graphics on transparent surfaces to ensure visibility of the interior when viewed through glass or liquids.

Limit double-sided rendering to necessary elements to optimize performance.

No need to include punctual lights; the platform provides its own lighting setup.

Ensure the model’s orientation and scale are consistent for uniform appearance across the platform.

Separate meshes based on their assigned materials.

Isolate transparent elements to improve rendering quality and reduce processing time.

Organize all meshes under a single Root (empty parent) node. This structure ensures compatibility with the platform’s renderer.

Models should not exceed 50,000 triangles for optimal performance on WebGL-based viewers.

Aim for lower triangle counts for smaller objects or secondary elements.

Avoid dense meshes; simplify where possible using LOD (Level of Detail) techniques.

Use textures with a maximum resolution of 4096x4096 (only if it’s necessary).

For less prominent assets, consider resolutions of 1024x1024 or lower.

Limit the number of unique materials to avoid excessive draw calls.

Reuse materials where applicable.

Ensure the final file size is under 20 MB for efficient loading on client-side web applications.

Larger files may negatively impact performance and loading times.

Limit the number of maps per material (e.g., normal, roughness, and metallic maps) to maintain performance.

Avoid overly complex shader nodes or material setups that may increase rendering time.
