I want to create an animation where a sphere moves. This sphere is going to be textured with a PBR work flow. However, the sphere will feature a relatively complex node setup, wherein one of the main elements is refraction.
Here is the issue...
The sphere is a placeholder object for the main character of a short film (sphere like main character), and will be in almost every scene. In order to make sense in the narrative, the shader for this character has to be semi-transparent/refractive.
Since this sphere is going to be in nearly every shot in some capacity, I want to keep render times for this object to the absolute smallest amount of time possible (preferably under 1 minute per frame).
Is there a way to optimize a refractive material or the lighting in the scene, or maybe perhaps there is a way to fake refraction, in order to keep render times as low as possible?
