I managed to export the xml from a mesh clothing the other day and put it in the meshesSL program and worked a treat. 

But now im getting this error in the revelator viewer when trying to export xml " DRESS-MAITREYA.xml (Content might take some time to download) " even get the error for a cube, anything. 

I've done clear cache. clean uninstall. different sim. nothing I still get this error and it never downloads. I've waited for up to a day.

What am I missing?

try to do that with the Hydrastrom viewer

that fix it . thank you !
