Please upload one of  samples from  Mesh/Sample Content .

If you can upload a sample, there is a problem in your model or exported COLLADA file.

What is your 3D modeling soft?
We can not figure out without seeing your model.
Upload a screen capture of your model.

I am not good at English, too  lol.

I have upload a sample mesh and it is not visible too.

I use blender 2.58.

2 month ago I upload the same meshes and all was fine.

Thanks for reply

I highly doubt this would solve your problem, but it's worth a try.

A while ago, I had, no matter what I imported, invisible mesh prims whenever I turned alpha textures off (shortcut is ctrl+alt+2) and I wasn't even aware of the fact that I had alpha prims turned off, turned it off my accident most likely.

This made my mesh prims invisible because I was reviewing the AO maps in-world, and those AO maps were .png files with transparant texture borders. So even with 1px transparancy on the textures of my mesh, it simply vanished whenever I had alpha textures turned offf.

Did you set the scale in the upload floater? It's set to 0 bei default, and as a result your model can be too tiny to see

[Sun Xaris]

Alpha textures are on.

[Sun Xaris]

Yes, that is it.The scale was set to 0.Thank you very much
