Made some test renderings using Klaus cornell box in 3DSMax Design 2012. http://revitforum.org/showthread.php...hlight=cornell
To better prevent burn out areas, Klaus 20000 lumen/1KW power beamer was replaced by a 6000lumen/2x35W OOTB fluorescent fixture.
The rendering in Revit with Klaus custom settings took 14min on my machine.
The file was linked as fbx via FileLink manager and no adjustments were made to materials, lights or cameras.
The exposure value and the light burn coefficient are exact the same as in Revit.
(There is a difference how Revit and Max apply gamma values))
Following rendertechnics/engines were used:
1) iRay: Rendertime: 14min, just hit render
2) MentalRay: FinalGather:
Rendertime:12min
Final Gather Precision: Medium, FG Bounces: 0
Image Precision: High, min 1, Max 16
Soft Shadows Precision: 8x, High Quality
Glossy Reflection Precision: 5x, High Quality
Glossy Refraction Precision: 3x, High Quality
Rendertime:13min
Final Gather Precision: High, FG Bounces: 0
Image Precision: High, min 1, Max 16
Soft Shadows Precision: 4x, High Quality
Glossy Reflection Precision: 3x, High Quality
Glossy Refraction Precision: 2x, High Quality
3) MentalRay: Importons and Irradiance Particles:
Rendertime: 11min
Importons: Density: 0.2 Trace Depth: 0, Traverse
Irradiance Particles: Rays: 256, Indirect: 3, Interpolate All, Interpolation: 128
Image Precision: High, min 1, Max 16
Soft Shadows Precision: 8x, High Quality
Glossy Reflection Precision: 5x, High Quality
Glossy Refraction Precision: 3x, High Quality
Final Gather: Disabled
Rendertime: 13min
Importons: Density: 0.3 Trace Depth: 2, Traverse
Irradiance Particles: Rays: 384, Indirect: 3, Interpolate all, Interpolation: 128
Image Precision: High, min 1, Max 16
Soft Shadows Precision: 8x, High Quality
Glossy Reflection Precision: 5x, High Quality
Glossy Refraction Precision: 3x, High Quality
Final Gather: Disabled
Rendertime: 18min
Importons: Density: 0.4 Trace Depth: 2, Traverse
Irradiance Particles: Rays: 512, Indirect: 3, Interpolate all, Interpolation: 192
Image Precision: High, min 1, Max 16
Soft Shadows Precision: 8x, High Quality
Glossy Reflection Precision: 5x, High Quality
Glossy Refraction Precision: 3x, High Quality
Final Gather: Disabled
Conclusion:
MentalRay in 3DsMax does the job better in the same amount of time.
Especially the new Importons and Irradiance Particles method is far superior than the native revit method.
