    Instead of continually using “said” or synonyms thereof, how about adding descriptions of the state of mind of the characters. Or, if that is not needed, and just two people are speaking, you can...

    Well, you said arcsine of the reciprocal of the Mach number, which is 2.5, so that’s what the expression “asin(1 / 2.5)” means. “GX” is the usual Blender key sequence for “move along the X-axis”, and...

    Yes, those Andersons. UFO was their first live-action TV series, though not their first live-action TV production.

    Has anyone else used Fracplanet? It will generate planets for you from various parameters you specify. You can then import the results into Blender and tweak them further and include them in scenes...
