In testing the first 400 frames, I found an issue with render artifacts. These stem from the falloff ramps of each splat in the set.
The solution seems to be to render the splats slightly larger and with no falloff for the first frames, and interpolate to the correct size and trapezoid splat type by frame 400. Here are frames 0, 100, 200, 300, 400.

| Trapezoid core: 0.35, Size: 150% |

| Trapezoid core: 0.35, Size: 125% |

| Trapezoid core: 0.35, Size: 125% (dust, nebulae), 100% (stars) |
