In secondlife, we don’t have morphing (shapekey) therefore use multiple layers (materials in Blender and faces in Secondlife) and change alpha with llSetAlpha.
HUD and llGetAngentInfo can control layers by Linden scripts.
Still it’s a primitive HUD but you can understand how we can control facial expressions by multiple layers.
Enjoy.
Great news!
Avastar RC4-812 also provides us “Weld Edge Normals” option in Tools shelf [Other] section as collada export option, in order to avoid visual seems (line) between objects.

Visual seems? Yes, you can see “Line” between objects or doubles vertices in smooth shading.
Why we can see such a “line” even though we adopted “smooth” shading in blender?
Because vertices on the line are “doubles” and vertex normals are different.
Here is a great video to understand Normals and Smooth shading by Avastar’s creator, Gaia Clary. It’s Good Job!!!!
Face normals
Vertex normals and smooth shading
In order to hide/avoid visual seems, so far we use [Remove Doubles] in Tool Shelf in Blender. However [Remove Doubles] means merging vertices to one vertex. If you would like to keep separated objects, you could not avoid visual seems between objects by normal functions.
Keep separated? Yes, if you would like to have over 8 materials in one object, you should separate object for more materials under secondlife mesh limits.
See “Mesh” limits below link.
http://wiki.secondlife.com/wiki/Limits
Why we need more materials?
We need “faces” for each facial expressions. With like a flip cartoon method, you can adopt facial expression to mesh head/face instead of morphing.
Eye part has 8 materials as 8 (prim) faces
Mouse part has 8 materials as 8 (prim) faces
Eye and Mouse part should be separated objects. It means we can see visual seems between Eye and Mouse parts.
But now we can erase it by Avastar “Weld Edge Normals” option in exporting collada.

PMX imported model? Non non, it’s mesh anime head “M3” from UTILIZATOR!
(Head only. Miku costume by GANTZ) with Wind Light, light/shadow and DOF rendering options
UTILIZATOR – M3 Mesh Anime Head in marketplace
https://marketplace.secondlife.com/p/UTILIZATOR-M3-Mesh-Anime-Head/4697296
With PMX imported mesh doll.(Applied Wind Light setting, without light and shadow)
With another M3 Head avatar. (Applied Wind Light setting, without light and shadow)
Realistic mesh head (hybrid avatar) “Nea” is also amazing work and this M3 Mesh Anime Head has so many facial expression patterns controlled by HUD.
This M3 Mesh Anime Head shows us high potential of mesh works in secondlife, I think, as well as Nea gave us.

Already we know, if we would like to reduce land impact – especially “download”, we try to adjust triangle limit number of each LOD level.
However if Physics value is so big, how to reduce it? [Physic] tab provides us [Analyse] and [Simplify] buttons but we have more effective way to reduce it if mesh model is linked objects one.
Again, if your mesh model is linked from several mesh objects, the following workaround is so effective. Your mesh model doesn’t have children objects, this workaround does NOT work.
reference wiki
http://wiki.secondlife.com/wiki/Physics_Optimization
According to the above wiki article, Create the following script in root prim, and execute it. When completed it, Script will be deleted by itself.
default
{
state_entry()
{
llOwnerSay("Setting all child prims to PRIM_PHYSICS_SHAPE_NONE");
llSetLinkPrimitiveParamsFast(LINK_ALL_CHILDREN, [PRIM_PHYSICS_SHAPE_TYPE, PRIM_PHYSICS_SHAPE_NONE]);
llRemoveInventory(llGetScriptName());
}
}
If you don’t want to make script or you are not familiar to scripting, you can do the same thing from [Edit] dialog.
Open [Edit] dialog and check land impact.
Except root prim (yellow line prim) in edit mode, check [Edit linked] and select children prim (blue line prim). Open [Features] tab and select [None] in [Physics Shape Type].
Already you can see 31 land impact changed from 38 on the above picture.
Try to select [None] in all children prims.
When Physics value is less than download, you had better stop this workaround. No more effectiveness is expected.
Also you can see land impact value is reduced from 38 to 8 in Edit dialog.
Enjoy!
