BoM and SIM packed with avatars!?

[Axel Naxos]

I was at a SIM yesterday for a BLM event ... as people arrived, obviously everything was slower ... ok, normal ...
But there were many avatars appearing deformed and naked ...
I do not speak English, but in my translator someone spoke ... "Oh, BoM is fu**ing this land!" and she said that after mentioning the infamous "forced nudism" ...
Although I use BoM in my AV, I don't technically understand the subject, but I was curious ... Is BoM good? On any occasion? Was the BoM connected to the nudity and deformation of the Avs?

It's not the BoM, it's mesh.  Mesh takes longer to render and thus folks end up naked and with parts all messed up.  Happens worse in really busy area.

BoM - Bakes On Mesh

Brings classic avatar texture baking to modern mesh avatars.

It basically removes the need for appliers and allows people to use old-school clothing layer items, the servers bake a texture made up of the skin, alpha, tattoo and clothing layers your avatar is wearing. This eliminates the need for mesh avatars to have multiple layers of geometry for skin, tattoo and clothing, combining this whole stack into a single texture. This baking happens long before an avatar travels anywhere.

BoM is an awesome feature bringing a lot of flexibility back to dress up, reduces the need for onion skinned avatars (maitreya's BoM body now omits all the extra 'onion skin' layers' allowing the user to only use extra layers if they need it), which significantly reduces mesh avatar complexity, texture load times and VRAM usage.

If you're on a busy region and it's loading slowly, that's because it's a busy region and your SL client is doing its best. Be patient, reduce your draw distance and ignore people who find something or someone to blame the lag on.

(the amount of data to be fetched increases dramatically as draw distance goes up, even reducing it by a couple of meters can have a huge impact).

Classic example of somebody blaming LL for their own mistake.

Maybe they meant nipples and bits showing, but does not that show on all mesh bodies before they are loaded and the clothes on.

I am using nipple pasties and crotch pasties on layer, so I am always PG. And/or I use underwear on layers. They are baked on and showing even when the body parts are floating around.

I suppose you are saying that "mistake" was to assume that what happened on land would be caused by BoM ...
Even because I came to find out ... or if it is the lack of language on my part ... it would be sad ...

BoM is great, I love it, and it really does make avatars rez faster, however, it seems that while a BoM mesh is rezzing, the system avatar appears. Those system avatars are usually nude* and often have weirdly deformed faces to trick kludgy Bento mesh heads into looking normal. That's different from pre-BoM mesh avatars which alpha-mask the whole system avatar to invisibility.

All told, net/net nudity might be about the same because with or without BoM the mesh body will rez in without attached mesh clothing. That the BoM body will rez sooner should partially (?) offset the mesh-rezzing interval when the nude system avatar appeared.

______________
*or maybe those initial system avatars get the same textures as whatever textures are baked to the BoM mesh? not sure.

Oh I like that very much; I'll try that.

Just in passing: am I correct in assuming that this BoM cube, and the system body, and the BoM Mesh body all are painted with the same baked textures?

Incidentally, I do something a bit similar: I wear a prim painted with a normalmap to trick viewers into pre-loading it, so it applies quicker and more reliably to the one layer of my BoM mesh body; otherwise the normalmap seems to lag far behind the baked texture loading, and sometimes annoyingly unloads and reloads repeatedly.

Yes - the bake service doesn't really know what the bake is going to end up on; it just knows, "Composite these and send them out on this channel."

In case anybody else wants to try the BoM texture pre-loading prim, here's a script you can drop in a prim to paint eight of the eleven possible BOM textures, each on a face, so you can then remove the script, shrink the carved-up box, and wear it somewhere inconspicuous. It might be kind of instructive about how BoM works, too, if that's still mysterious. (I think you can set all sides to 100% alpha and the textures will load just as well.)

list BOM_TEXTURES =
    [ IMG_USE_BAKED_HEAD
    , IMG_USE_BAKED_UPPER
    , IMG_USE_BAKED_LOWER
    , IMG_USE_BAKED_EYES
    , IMG_USE_BAKED_HAIR
    , IMG_USE_BAKED_LEFTARM
    , IMG_USE_BAKED_LEFTLEG
    , IMG_USE_BAKED_SKIRT
    , IMG_USE_BAKED_AUX1
    , IMG_USE_BAKED_AUX2
    , IMG_USE_BAKED_AUX3
    ]; // Sort the ones you don't use to the bottom; uses 8 of 11

default
{
    state_entry()
    {
        list paramList =    // carve a box to get eight faces
            [ PRIM_TYPE, PRIM_TYPE_BOX, PRIM_HOLE_DEFAULT, <0,0.875,0>, 0.5, ZERO_VECTOR, <1,1,0>, ZERO_VECTOR ];
        integer face = 8;
        while (0 <= --face)
            paramList += [ PRIM_TEXTURE, face, llList2String(BOM_TEXTURES, face), <1,1,0>, ZERO_VECTOR, 0.0 ];
        llSetLinkPrimitiveParamsFast( LINK_THIS, paramList );
    }
}

Just for completeness: Apparently this BoM-rezzing oddity is already fixed in some viewers.
