Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

I used a hdri-image to light the scene but disabled primary visibility cause I need a dynamic background. therefor I mapped a procedural shader to the camera´s environment tab - used an envSky_node. under it´s Cloud Attributes tab I mapped a 3dcloudTexture. it´s placement_node´s Translate attribute is keyframed from 0 - 1 on x-axis over the whole scene - so the clouds are moving slightly. in the envSky_node the elevationAttr is animated as well from -20 to bout 70, so I get a anim from dawn till dusk. this is my background image for the scene. reflections tho come from the HDRI cause the envSky is just a imageplane and doesn´t enlight the scene. It could when pluging the output color to the cameras backgroundColorAttr, but that doesn´t give a good lighting.
in addition I placed a directional light with the same angle as the inital elevation direction, grouped the light to itself and connected the elevationAttr into the lightGroup´s X-rotation. so the directLight moves with the sun from the envSky shader and I get an additional light casting raytraced shadows which seem to come directly from the procedural background image.
well, so much for initial light setup. next big thing will be the shaders which give me the creeps allready.

maybe cause I use the envSky for reflection? checked it in the imagePlane - "visible in reflection/refraction"
what happened?

the envSky´s "Visible in Reflection" attribute - this might also be a bug. well the texture is kind of visible but only the summary of the sky shaders RGB levels. so I got a slightly more bright bluetone in all reflections. this might be cause I connected the envSky´s outcolor into the camera´s backgroundColor to get a dynamic global light for FG driven by envSky_elevation instead of the HDRI file. but there´s no other way than connecting those attrs.
now I have to get my true texture reflections!
