CG Artists Toolkit: HDR Lighting, Displacement Maps and Ambient Occlusion

HDR Lighting

 Below are the renders from creating an HDR dome using a composition of five images at different exposures. After cleaning up and unfolding them to create a map they were assigned to a dome and a reflective NURBs sphere used to reflect the dome. Unfortunately there is some puckering in the final render.

Displacement Maps

 Below are the various renders of a dinosaur head using displacement maps, transitioning between Mudbox and Maya.

 Here is another example of displacement mapping, using a toadstool. 

Ambient Occlusion

Below are three variants of Ambient occlusion. The first process involved the node being plugged into all the shaders in the scene. 

The second involved plugging in the Ambient node into an area light, firing the Occlusion all around the scene. (Far less time consuming than the first method)

The third and final method was to create a simple Ambient occlusion render pass to be composited later in Photoshop.

Cg Artists Toolkit: Instancing Objects, Instance Rotations, Goal Weights and Animated Instances

Instancing Objects

Below is an example of instancing objects. The sample here is a conveyor belt seemingly churning out objects.

Instance Rotations

In my attempt to complete the instance rotations file, I hit a flaw somewhere. I have a feeling it may be around the point in which I created the 360 arrows in their rotation. I realised in my outliner I was missing a second group (the instances group I think) and then later on Maya kept throwing this error message at me.

Error: file: /Applications/Autodesk/maya2013/ line 491: Could not find attribute named ".cycle"

In any case, despite following the tutorial, I have arrows that fire well, but have no rotation. (Which was the point in the exercise.) So they're all at the same angle :/  I think I will have to give this one another go another time.

Goal Weights

 The videobelow is a playblast of the goal weights tutorial. This took a rather long time to complete what with competing with error messages and being left uncertain as to what was wrong or if it affected anything. Despite my arrows ending not quite right, my butterflies did start to behave themselves.

Animated Instances

Below is an example of animated instances. A spider-bot invasion climbs down a ramp.
