So I'm having issues importing and saving models in Houdini Apprentice 15.5.673 Windows 10. Half the time when I import an obj there is no mesh brought in, but there is the node indicating the model in the side panel and that the model is not hidden. Sometimes a model successfully imports, other times it doesn't. I am exporting Obj's from Blender and sometimes I have to try multiple exports for an obj to load into Houdini.
Once I've actually gotten my models imported, I save the file and close. Next time I go to open the Houdini file there is nothing there except the nodes for the meshes on the right hand side again. No models though. I've tried selecting the node for the mesh and scaling it up, but nothing appears. This is happening every time. I feel like I always have the worst of luck trying new programs and they always bug out on me half the time.
Any help would be greatly appreciated.
More issues for a first timer.

Hi, there are a couple of things you can check to see what might be happening.
1. Select the file node/model. Press G in the viewport, this will focus the camera to the selected geometry.
2. Middle-click on the file node. - This will give you a pop-up box which displays information on the file (model). Check what size it is. (Houdini uses 1 unit = 1 meter) It's likely that your model is either very small or very large.

Share your file and we can have a look.
Just a guess:
Filename of the model is set to tree$F.obj
($F is a global variable holding the current frame number.)
So when your are on frame 1, it expands to “tree1.obj”
The error states you're doing stuff with a timeblend sop. Maybe the file-sop is evaluated at another frame number than 1, so that now the file-sop is pointing to a non-valid filename (e.g. tree2.obj)?

Thanks guys, you were right, that $F variable was the issue due to there bing a number to designate several files. So it was choosing a collection of files of say tree01, tree02, and tree03 rather than one single file. Ticking that box robsdesign did the trick! Thanks very much for all the help, glad to see there is a good community of support in this forum!
