Cheers, Z!

The reflections were doing my head in in the population render.

They appear wrong, somehow off-centre and pointing towards the lower-left. Or, possibly just 'squashed' together on the diagonal(which is the Z axis' direction. Single objects were fine, it seems, a few render retries were still required because soft reflections are very erratic for me.
Render = 0.5 detail(RTE)
AA = 4 Mitchell-Netravali(1/4 first samples)
GI 1/8(supersample) Blur 4(possibly should have left this at 8 )
Reflective shader softness = 0.1, samples 24
No sunlight, no atmosphere.I didn't think this was so low for RTE. Does anyone know if reflection samples are heavily detail relative? Raising them to 32(default max) wasn't taking full care of them either, but it was adding a power to the render time.
Anyway, silly Brycean scene, no matter really.
