Deep in the warren-like tunnels of the Second Life viewer code base lurk many beasts that hide in the shadows. One such beast that often shows itself at the most unexpected times pouncing upon poor unsuspecting builders, is known as the MOMINAS (Material Of Model Is Not A Subset).
TL;DR - enough with your silliness Beq, what's yer point?
OK, the boring version. The next Firestorm should have my rewritten mesh validation that supports proper material subsets. You will no longer be forced to keep a "single triangle" placeholder cluttering up your LODs. Furthermore, two new error codes have been added to replace cases where past laziness has reused the same error code for very different issues.
Back to our tale...
The Tale Of The MOMINAS
It's a regular Friday evening at the builders' tavern, "The Prim and Proper", and many regulars are clustered around the small tables or slumped at the bar. All of a sudden, the door flies open, drawing mutterings about better door spells and smooth rotations from the occupants. A forlorn figure stumbles in from the foggy evening outside. Battered and bruised, their overalls torn and smeared with what everyone hopes is grease, the new arrival stumbles to the bar.
"Pint o' bane, please, Mal", mumbles a tired, somewhat subdued voice.
A tankard of foaming beer slams onto the bar, accompanied by a loud chuckle.
"Blimey, someone's had a bad day of it. There ya go, get that down ya." Malcolm, the gentle giant of a Landlord at "the Prim" has seen it all in his time.
The newcomer mumbles a thank you and sips at the beer. A minute or so passes, the background babble of the pub returns to its normal levels.
"All day! All bloody day...!" The outburst takes a number of customers by surprise and heads turn towards the newcomer again, who is staring, wild-eyed and unfocused across the bar, their arm protectively wrapped around their drink. "Fighting them, time and again, one after another. Every time I get rid of one of them, another leaps up in its place." A pause, a large gulp of beer and the newcomer turns, "MOMINAS!", they exclaim woefully, and a look of pity and recognition spreads across the assembled faces.
"They wasn't never meant to be, ya know." A cracked old voice, suggests as old Alex emerges from the shadows, ready to impart the acquired wisdom of his many years. Ignoring the questionable grammar, the newcomer turns to listen. "They's gotten too full of 'emselves ya see. Yer common or garden MOMINAS was only meant to tell you when you'd broken the laws of LOD, but they've been out o' control for years. Bad as dem MAVBLOCKs if you asks me. Prolly worse now since The Taming."
Mutterings of agreement, echo through the crowd. "Back in the day, the MOMINAS, was bred in the Lab, special-like, as a guardian to sniff out material errors in LODs that would corrupt your constructions. But "Material Of Model Is Not A Subset" to give the MOMINAS, its proper name, escaped the wards and cages of the Lab when Mesh was released and it went feral. Since then the MOMINAS has lurked in dark places, attacking lone builders without cause, spreading confusion, and worse....", the rheumy old eyes scanned the bar, flourishing his empty tankard, "... far worse...", he gave a little cough and smacked his lips, until a fresh tankard of frothing brew was thrust towards him by Malcolm. "Inefficiency!" He exploded, "it makes your stuff worse not better" the old man cackled, and a shocked hush spread,
"yes yes," he mused, toothlessly. "They was meant to make sure your LODs were aligned to the HIGH LOD. Even those first year's at the academy get taught the laws of LOD by rote; how every LOD must have exactly the same materials as the LOD above, but the laws is ... corrupted." A spray of spittle emphasises his disgust. He nods to himself and slurps his beer.
"Subsets, ya see, Sub Sets." stressing each syllable as if in the hope it would give it more meaning. "It was meant to be that you only 'ad to 'ave a proper subset. If your house was built of Brick, Stone, Glass and Wood, then your LOD could use any mix of those, but not add Metal. A Medium LOD with no Glass should be fine. But oh no, no no no no no the MOMINAS had other ideas. and for years they's been forcing us all to think we had to have all the materials in every LOD. That ain't no subset! Any fool can see that." Banging his tankard down with a crash upon the bar as if to vanquish the monsters, the old man paused, looking slowly around as if to gauge his chances of gaining another free beer. But before he could try his luck, a voice spoke from the shadowy corner.
"You're mostly right, old man.", said a woman's voice, its owner stepping out of the shadows. "but things are about to change." Whispers spread rapidly through the tavern, replaced just as quickly by an expectant hush."
