Mesh/Sample content page is broken

[ChicByTrinity]

http://wiki.secondlife.com/wiki/Mesh/Sample_Content None of the files can be downloaded. And when I try with right-click I just get a corrupt zip file. :(

[Drongle McMahon]

Yes. Something has gone wrong. To be honest, I'm not sure these files work with the current viewers. They were made a very long time ago before the beta became open. They were also not well optimised for the current LI calculation system. I did make some updated versions of mine, but I don't think they got as far as being placed there.

[ChicByTrinity]

I just need an example file. I'm using 3ds Max 2012 and I exported a mesh (.dae) I had made last year for IMVU, and when I uploaded it the preview windows showed me some crap - only a few polygons in highest detail mode. So I think I want to see a working mesh to see what's wrong with my meshes.

Could be a ton of things, I'd suspect overuse of materials or overuse of geometry first.

It would really help others trying to help you if you posted some pics with some data and wireframe of your model.

2012 had a bad exporter for SL too, but I don't recall people having the issue you describe with it. A simple first step could be replacing your exporter with 2013.2 (FBX plugin) or newer.

Try this. It's just a cube.

Ok, this time I saw a white cube (the code provided above). Then I tried with "medium" and I saw only a white triangle. Not a pyramid, just a flat triangle.

And "upload" button is greyed out. (another broken page is responsible for that. I'm on the beta grid).

And in 3ds Max. Maybe I have wrong/invalid materials on it?

[Kwakkelde Kwak]

You can use up to 8 materials in one object, the triangle you see on medium is one of the 49 specified in the uploader I bet, the rest is probably too small to see. For angular objects like this you should really use LoD models or you end up with either a visual mess or with an enormous graphical load with matching high landimpact.

[Drongle McMahon]

Yes. It looks like more than 8 materials. The uploader just removes all triangles with the 9th and higher materials. That's why parts of the model are missing. What is there looks alright to me.
