I have a project, and it has an object that has always rendered correctly, but one day when I open the project and make a test render, the object has disappeared. All the settings are normal, the object, and all of it's children render display in the object outliner set to true. I really don't know what happened to it. Can someone tell me what I should look through to diagnose it? Sorry I cannot provide much detail. What I've explained is all I know.
Edit: I am uploading the .blend file at http://www.pasteall.org/blend/34719 This is a Minecraft scene. It is the wolf that doesn't render. At one point it did, but now it just won't. The wolf has particle properties. I don't know if that matters, but it could. Look through all the wolf's properties to try and figure it out.
