The last thing is that MtoA doesn’t support color space configuration in file node currently (v1.2.4.3). We need to set all parameters in gamma correction to 1.0 and set display gamma to sRGB, Rec 709, etc: When we turn on the color management in Maya: Maya supports color management after Maya 2015, but few things should be noticed. The best practice of photo-realistic rendering should be done with linear workflow. Those problem would cause discontinuous shading artifacts.face penetration, discontinuous tangent/normal vectors, etc.The number of triangles would affect the render performance since ray tracer needs to load all the objects in the scene before tracing.Use aiUtility to examine the problems of geometry such as:.Arnold will stop rendering process immediately when it fails to access target textures.Check output log for any missing or broken textures.Besides, scanline EXR has memory overhead when rendering many AOVs. Reading tiled EXR in Nuke 9 is 25 times faster. Turn off tiled, since most compositors prefer scanline format.Set compression format to zips and enable half-precision, auto-crop to save storage.

This is very useful for render process diagnosis.

Change log verbosity to Warnings + Info.

Always using tx! It can significantly reduce I/O time!.

Here is the summary about what I’ve learned from experience, hope it would help any Arnold user. Which means that when we switch from one ray-tracer to another, we had better use different strategies to adjust render settings. However, if we blindly increase the number of ray samples for every render scene, we would not always get a cleaner imagery.

works with photon-map or irradiance caching, etc).Īrnold is an un-bias uni-directional path tracer with a remarkable importance sampling mechanism and great memory management to achieve amazing performance excellence. Although they are all categorized as ray-tracer instead of rasterizer, the infrastructure of each implementations are quite different (i.e. All photo-realistic ray-tracers are trying to solve the rendering equation.
