Hi Spritely,
I’ve made a small update so that there’s a different material for each polygroup. I’ve added a number at the start rather than a letter, as that was simplest to implement. I’m not a SL user so I’d appreciate it if you can test and let me know of any problems! (The plugin doesn’t restrict the number of polygroups/SL faces but ZBrush has a maximum of 1024 
)
Thanks,
This worked great, I noticed a few things 1) when SL says more than 8 faces to a prim, what they do is create 2 prims, with the first 8 faces on the first prim and the next 8 faces on the next prim and so forth (programmatically, it is 2 prims, but somehow the land impact is less than if the prims were brought in separately). 2) since the sort order is alphabetic, the 10th face is face 0 of the first prim, not the first face (1). The way to fix this is to 0 pad the numbers, so it would be 001,002, …, 010, 011, …
Not knowing zScript very well but something like this
[VarDef, prePend, “”]
[if, counter < 10,
[VarSet, prePend,
[StringMerge, “00”, counter]],
[if, counter < 100,
[VarSet, prePend, [StringMerge, “0”, counter]],
[VarSet, prePend, counter]
]
(This is just from reading the documentation, and probably doesn’t compile)
and 3) Though it works the way you have it now, and doesn’t act any differently than when i manually added the materials to the materials list at the top, technically they should be listed.
I want to Thank you for the quick turnaround on this, I believe this will help the Mesh content makers of SL that use zBrush very happy (i suspect that they will ask for a back fill to version 4.6, but like i said to my graphic artist, “just upgrade now that this tool works with SL”), If you want someone to look over and mod it more, feel free to contact me as I have spent a long lifetime as a programmer.
Many thanks Spritely, that’s very useful. I understand perfectly about the numbering and will update in the next few days.
Is it possible just to call them material_001, material_002, … instead of the names of the subtool? We are having to bring in each level of detail separately since the mesh cannot be exported with LOD since there are no subdivisions, so each level is a decimation of the highest detail. If the materials are the same name between all exports then I don’t have to change the names to match between files.
I’ve done that - try the latest version. I think that should work OK.
Hello, I download it and it works real well. The last thing I am trying to figure out is why the faces sometime appear to randomize. I think this is happening during the merge down down functions. I will research more in the morning, as i was writing this up, i actually got the last LOD mesh object to have the correct face order, and i have been beating my head against the wall, before that.
So, After a good nights sleep, i started on my next mesh object import (Yes, these are our original creations). I figured out what to change in the file to change the face order on import into sl. I do this by changing the material in the <triangles material=“material_nnn” count=“nnnn”>
<triangles material=“material_nnn” count=“nnn”><code>
<triangles material=“material_nnn” count=“nnn”>
<input semantic=“VERTEX” source="#obj_-vertices" offset=“0”/>
<input semantic=“NORMAL” source="#obj_-normals" offset=“1”/>
<input semantic=“TEXCOORD” source="#obj_-map1" offset=“2” set=“0”/>
<p>…
</triangles>
</code></triangles><code><triangles material=“material_nnn” count=“nnn”></triangles></code>
blocks.
I don’t see a way to get information about the subPolys(?) that would give you a handle to sort on though.</triangles>
Spritely,
I’m not clear of your process. Are you merging separate subtools and then require the original subtool order?
(You might prefer to take this discussion off thread, so we can sort it out before I post an update, in which case, send me a private message.)
Just a heads up that the latest version (4R7_05) will list materials based on subtool order if you merge subtools before exporting a mesh.
Many thanks for your work on this excellent tool. I’ve been using this plugin with success, except for one problem: it seems to scale my ZBrush models down by half.
I did some tests with a 1 meter cube in SL: exported it to Blender, re-exported back from Blender into SL; it was still a 1m cube. But when I export as a Blender .obj to ZBrush, then immediately save as a .dae using your plugin, then upload to SL, it becomes a half-meter cube. I can cure this by doubling the scaling in SL’s upload tool, so maybe it’s not a big deal? But I’m wondering if I’m doing something wrong. (I set my units in ZBrush so that one face of the cube = 1m long, but I’m not sure that matters.) Help, anyone?
is the _05 version newer than _06? for some reason i already have _06 installed but when i try to install the _05 version it asks do i want to replace the 2/13/16 file with an older 11/30/15 file… i know i didnt upgrade zsculpty tools after sl modified the ‘‘limitless’’ face patch for mesh. which file has the mod for the no limit on faces or polygroups?
There’s a Rigging panel with which you can make zspheres be the bones of the mesh and move it around to how you see fit.
will this plug in work with 4r8?
I’ve just updated for 4R8 - see link in first post. (I’ve also restored the link for 4R7 version - sorry about that.)
marcus, thank you for keeping this updated all these years! 
hey marcus thanks 4 all the work you put in 4 this plug in. will this work in zbrush 2018?
gracias…magnifico.
Please make new update for zBrush 2018.1 and 2019 too import collada and export collada on .dae thanks.
I am use SecondLife and OSGrid. Many people use zBrush try export .dae and upload to SL / OSGrid
Hi there - I decided to have a go at this old Zbrush to SL thing again, texturing something for a friend, but I cannot seem to access the plugin for version 4R8. Not sure if that would work with the later version, but I have have 4R8 installed still. Would it be possible to make this plugin accessible for download again,?

anyone still looking for this for SL, OSGrid the new 2021 6.2 has dae built in
