Problems you might face importing rigged mesh and the solutions I found that worked for me:
The following assumes you have already used Meshes SL to successfully rip a model from an .xml file produced in e.g. Hydra and are trying to upload that model.
Problem: Material is Not A subset of reference Model:
Usually caused by a part of the mesh not having a material assigned to that a part or vertex group of the mesh.
Sometimes you will find a mesh that has a part of the mesh A.) alpha channeled B.) Face orientation facing the wrong way. and has no material assigned, especially if you skipped the alpha texture download.
There are two ways to overcome this problem:
1.) Delete all unneeded pats of the mesh. e.g. mesh bodies, only import one Layer at a time and make sure all parts have a material assigned
Including root prim or DEMO sign etc or better; delete all unneeded parts.
Mesh bodies are onioned into different layers for tattoos and cosmetics etc. Import one layer at a time, worst scenario: part-by-part
1a.) Object mode: With mesh selected, press "show overlays" button in the top right hand of the 3d viewer - under geometry, check Show face orientation to ensure all face are facing outwards and are blue, flip normals or delete any part that has the incorrect orientation.
2.) The long way:
Open file in blender and go through each and every part of the mesh and re-assign the materials.
It is important that you have saved all the textures and recreate the materials, by selecting each the part of the mesh.
Selecting the material that blender highlights and drag and drop the textures you saved for the object into the node editor and connect diffuse to base color connect, Normal to normal and Specular to specular connector.
With the part of the mesh selected, hit "Tab" and go into Edit mode and select all by hitting "a" and then select "assign" to assign the correct material to each part of the mesh.
(If you are attempting this with a mesh body, there could be up to 8 materials per part of the mesh. e.g. The chest would have 8 separate materials, all using the e.g. upper body skin texture. You will have to drag and drop and assign for each part, and mesh shapes can have up to 4 layers of mesh for each section... it is tedious work, so just work with one layer at a time. This is the best method and has always worked for me.
Problem: Error importing due to convex hull or physics block etc blah blah:
Solution:
a.) Make a simple cube in blender. Save cube as Dae, unrigged.
When uploading, go to physics Tab in FS or Hyadra etc and choose from file and navigate to the cube, sometimes more that one cube selected works better depending on the size of the mesh.
b.) next option: Open object in Blender and apply a Decimate modifier and make a really bad low poly copy of the mesh. Apply Modifier and hit cntrl+A to apply all (all in object mode).
Save as Dae - Unrigged
Select as physics object.
In both cases reduce LOD to 0 in Lowest field
c.) Reduce LOD in to 0 in Medium, Low , Lowest - and upload. Quick and easy lemon squeazy.. but you cant see Jack from a distance.
d. ) Import each part separately e.g Broberry jeans from Deadwool: i uploaded each leg, the pockets and buttons seperately, wore every thing, selected and linked and then took them off , rezzed and textured.
I use Hydra and the Hydra textures feature to ensue I rip all textures including normals and specular to get a good result.
TIPS:
When importing a Dae into blender 2.8 make sure you hit the gear icon in the impot window and check the following:
Armature Options:
Fix Leaf Bones
Find Bone Chains
Auto Connect
Keep Bind Info
Therefore your mesh will import into blender correctly and not a big messy square pile of unorganised rubbish. Also apply rotation scale etc then transform , set origin to geomirty.
TIP 2.
See Dae file quick and easy without opening Blender etc: opens mesh files as easy as viewing an image
use :https://github.com/acgessler/open3mod
It's also useful for opening files with a Dae cannot parse file error and also quick and easy obj. to dae export
Excuse the typos
