SCAD X HARBOR - Week 5

Hello, this is my forth week of the Scad x Harbor blog!

Feedback From Mentors:

Vi:

Awesome to see you listened
Shot 1: the environment in background is dark/composition
Shot 2: Is it needed to add steam?

Hailey:

Remove shot2, it's the same with shot3
shot3 - defocus background, atmosphere smoke
shot6 - title needs to pull out more

Kyle:pam

Pan now 3D/Paralax
Not crazy, slow subtle camera move
Combine shot 2 and 3, it is cool from top down, and have camera orbit around the pouring
shot3 - focus on what's important/push back what isn't
shot5 - dof/background may blue/deep compositing bubbles
shot6 - too tight - perfect it

Billy:

Background out of focus
Don't render with depth of field

Joleen:

shot 1 top down? Connect the flame to the melting

After our discussion, we decided to combine shots 2 and 3 into a single shot with movement. The camera moves downward and circles around the pouring molten platinum. For shot 2, I also added steam and atmospheric smoke in the background to enhance the factory environment. This is what the final looks like; I also need to adjust the environment to smoke in the following week.

Render

I have had several tests of different viscosities of molten platinum and tried to find the most suitable one. For my latest test for the shot, I chose viscosity 40.

Viscosity: 20

Viscosity: 40

Viscosity: 30

Viscosity: 100

Separated Layers:

Caleb separated the smoke layer and beauty layer in Karma. Following the instructions from the forum post, I followed the steps and achieved the result. Use the Render Geometry Settings node, select invisible objects in Primitives, and choose 'Invisible to Primary Rays (Phantom)' to exclude the unselected objects.

Environment Smoke:

Based on Professor Fowler's suggestion, I tested two different smoke solvers in Houdini: Smoke Object Sparse and Smoke Object, to compare their speed and smoke effects. The results show that Smoke Object Sparse is much faster than Smoke Object.
