Arnold GPU Limitations: Ignoring Round Edges on Instances

[3dvfxprofessor]

Arnold GPU is not production ready for three reasons:

- It does not support out-of-core yet (not critcial for most of the scenes)
- It does not support branched samples
- It looks like that instances will ignore the Round Corners shader (compare the two renderings)

My still life works good because it just uses a simple shader with diffuse, roughness and normal maps. And a slightly DOF.
This LEGO scene is using SSS and transparency. Without the control over the samples for Diff, Spec, Trans and SSS I am forced to use high samples for the whole picture just to get rid of the SSS noise and this ends up in higher render times in my case.

Even with a similar time there's still too much noise in the GPU rendering.
