If the additional lights are too strong or weak, they can disrupt the overall lighting effect. Matching Ambient Lighting: Align the intensity of the ambient light with the skybox brightness, so shadows and highlights transition smoothly, avoiding jarring bright or dark areas. 6. Optimizing Performance While Maintaining Visual Quality Adjusting HDR skybox textures can affect not only the visual outcome but also performance, especially in real-time rendering environments. Therefore, performance optimization is essential when altering brightness and contrast. Lowering Texture Resolution: High-resolution HDR textures can consume a significant amount of memory and processing power. If the quality requirements are not too high, consider reducing the texture resolution to enhance rendering performance. Using Compressed Formats: In Unity or Unreal, you can utilize compressed texture formats (like BC6H or ASTC) to reduce the file size of HDR textures. This helps improve performance without noticeably sacrificing visual quality. 7. Testing and Iterating Each scene has its unique lighting and design requirements, so testing and iterating adjustments to the brightness and contrast of HDR skybox textures is necessary. Testing in Different Lighting Conditions: Test the HDR skybox under various lighting conditions, such as day, night, or indoor settings. The performance of brightness and contrast may vary drastically depending on the lighting. Gathering Feedback and Refining: Share the initial results with team members or clients, gather feedback, and further fine-tune the HDR skybox&rsquo;s brightness and contrast if needed. By adjusting the brightness and contrast of HDR skybox textures, you can significantly enhance the visual quality of 3D scenes, boosting the overall lighting effects. Through material settings, post-processing, and image editing, designers have flexible options to meet the specific needs of different environments, ultimately achieving the desired visual impact.
