Thank you for your thoughts: Much appreciated.

I should point out that my posts are mostly 'Test Pieces', experimenting with imports, scaling, texture-conversion, FX etc etc. And, yes, having fun...

I began using Poser (P3 !!) as an architectural visualisation aid. My semi-pro CAD suite had proven unable to furnish a sprawling 'Caravanserai' project's Medieval-ish rooms beyond rudiments, or handle figures beyond flats and very-low-poly static mannequins. Happily, those 'CAD', 'Home Design' and 'Poser' packages all liked 3DS, so I could port, tweak, port etc. P_3, then P4 provided in-room 'Level of Detail'...

Happens I began using CAD after the square desert 'castle' where I'd set a fantasy tale sorta-grew a fifth corner. Oops !!

I'm no 'visual artist', scene figures merely supply scale, serve as place-holders. For me, the important factor for figures is may pose, should need arise, hence my running battle with FBX rigging woes...

IMHO, is getting harder and harder to do the just-beyond-simple things in Poser, and P_12's cruel culling of Material Room 'Basics' is not going to help.

Scene Luminaires ? Gotta jump through flamin' hoops to light them, and they have an undocumented maximum surface brightness...

I've now learned several work-arounds.

Mirror-surface ? There's no obvious 1-click solution, just uncertain, twisty paths through thick jungle, instead of a 'topographic map' with trails and fords marked.

I'm currently collecting mirrored freebies, intend to use them as trig-points to build that map...

Back before you needed immense libraries and run-times to even say, 'Hello, World !', I used to code in BASIC and 6502 Assembler. We had 'Top Down' and 'Bottom Up' programmers. Both types thought my self-taught approach weird, for I began in middle with core algorithm, spiralled outwards...
