Rendering Competition: Chaos in Harmony


Technical Challenges

How we tackled the challenging task of rendering a high quality scene with realistic lighting, atmospheric effects, and efficient sampling.

1. Achieving Realistic Lighting on Mars

Our initial goal was to enhance the realism of the sun's glow, but bloom could sometimes create harsh contrasts, resulting in an overly bright scene. Using reflective materials rather than a traditional texture was a challenge since it sometimes created harsh contrasts and made the scene overly bright. We opted for an abstract, artistic look rather than a traditional texture. However, we were unable to achieve a perfect result despite multiple adjustments. We found that the sun without bloom, using only an emission material, looked more visually appealing, but on the final site, we decided to keep the bloomed version.

2. Thin Lens Depth of Field Issues

We had to use a thin lens model to get a realistic depth of field effect, but it initially caused focus distortions. We had to manually adjust focus each time since Blender exports scenes using the Lightwave plugin with only a perspective camera. To achieve the correct focal point, careful tweaking was required.

3. Computational Limitations

We created our render using a base model MacBook Air 2024, which struggled during rendering due to its limited hardware resources. We optimized settings to achieve a high-quality final render within our hardware constraints, despite the limitation of our hardware resources.
