This is looking really good Mark, Keep it up ! :)
The hard part is this one tunnel (I'm using the same tunnel for the sporozoite intro as a base) is becoming one of the largest scene files in my project library.So I've got several versions of it that have different variations (hepatocyte cells here, the sporozoite travelling about on another), I might have to start creating render passes on disparate scene files.
Awesome! Well done : D
nice and dynamic, Mark :)
