Experiment Render Speed Between Arnold & Blender

In seek of method to make render in fast review, try to blend workflow from Houdini magic work into Blender for finishing as modelling/shader in Blender has faster workflow but actually found that Arnold really nuance and give a nature look than Cycles. Eevee does not count for current my work's requirement, but really fun to see it in realtime.
