I keep trying to make stuff 'mirrored', but what works for one model won't work for another.

Worse, I neither understand what I've done right nor what has gone wrong.

Part of problem is a great chunk of Poser manual's 'Material Room' documentation describes the wondrous, one-click facilities provided by 'wacros'.

Which I could not find...
I shrugged, decided that was due to removal of deprecated Python version.

This latest foray into reflectivity etc was spawned by a MMD/PMX freebie, a panel van. Actually one of four versions in set, sharing many parts. Converted to OBJ+MTL using 3DOC($$) or free PMX Editor, there were a few glitches, a few texture tweaks required, but it rendered okay in Poser.

Except for the 'wing mirrors', which remained stubbornly 'matt'.

They, at least, had their own material call, but used a complex texture map, which lacked any obvious mirror shapes. Took a 'binary chop' with half a dozen iterations to locate...

So, not only did I need reflection, but I also had to mask the effect.

I found several tutorials by JCH, sadly only for P5/P6, and the Material room has evolved far since then.

I'd just been wrangling those silly horizontal dots marking hidden menus at foot of Library, having mis-clicked them, when I noticed similar vertical dots at right of Material Room, Advanced.

Um, yeah, due Covid, I'm a year over-due updating my arm-length-focus 'VDU' glasses...
But, surely not ?
Indeed, like Poe's infamous 'Purloined Letter', wacros have been there all along...
D'uh...

An evening of experimentation ensued.
Eventually, I found the 'reflection' wacro spawned three 'nodes', per blue trail, but I could dispense with its two subsidiaries. If masking required, add new node, 2d-textures, image map. Drag its 'port' to reflection value, per lower green trail. Link to 'reflection' appears automatically. Add image call. White reflects...

Care: render default may change to firefly, as wacros over-ride preferences. Just re-select superfly.

I could not make Poser Primitives' 2-sided square behave, my simple 'map' refused to wrap correctly. Will explore. Single-sided square was okay. Box was mostly okay, but showed artefacts. Will explore these, too. And I must tweak 'metallicity' and 'smoothness', where-ever they may lurk, to minimise the ripples / freckles...

 

 

 

Very much 'Work in Progress', but several 'pitons' up steep learning curve...

There's nothing like a dozen quickie test-renders to help wrap wits around problem...

This is not the best way to do reflections, but may help.

Do Safety-scan, of course. Un-zip some-where convenient, there's a 'ReadMe' in the mini-Runtime.

Just two one-sided squares set at right-angles. One entirely mirrored, other with a blank patch.

Not a brilliant render, but 'Proof of Concept'.

Thanks, I'll try it, but tomorrow
I'm on P7, but might work with some tweaking...

Worked in P7 out of the box (only changed the version number of the mt5 to "7" to avoid the error message)

Yay !! My freebie actually works !!
