[SOLVED][Editor]StaticModel doesn’t refresh geometry changes

sabotage3d

Hello,
I remember before when I create a Static Model in the Editor pointing to an mdl file it was refreshing if I change the mdl. Now it is no longer the case, I have to restart the Editor to see the changed model.
Is there a specific preference or setting I have to change for the old behaviour? I also just compiled the latest from github and the behavior is the same. The resource browser works as expected it shows the model change instantly.

This should not be related to the editor itself (though only the editor uses resource reloading presently), but points to a regression in either the StaticModel or FileWatcher code. Thanks for notifying.

EDIT: On Windows this works fine, for example creating a built-in box object and pasting the Sphere.mdl over Box.mdl, and back again. Will check other OS’es later.

Thank you for your reply cadaver. I am under OSX but it should be same on Linux. In order to see the issue write a Sphere geomtry to test.mdl create the Static Model in the editor point it to the test.mdl and write different geometry let say a Cube replacing the test.mdl. It will still show the Sphere geometry.

Tested also on Linux and OSX. I didn’t get the bug to appear. The sequence I used:

  • In Editor, create builtin object -> Box
  • In bin/Data/Models directory:
    cp Box.mdl _Box.mdl (make backup)
    cp Sphere.mdl Box.mdl (observe box turning to sphere)
    cp _Box.mdl Box.mdl (observe sphere turning back into box)

Maybe you’re doing something different that makes the bug appear?

I am under OSX 10.10.2
I jus tried this:

  • In Editor, created StaticModel from the shelf.
  • In a custom directory $HOME/Data/models I copied Sphere.mdl and Box.mdl from the original Urho3d Data directory
  • On the model field of the StaticModel, clicked on pick model and I choosed Box.mdl from $HOME/Data/models
  • The viewport was showing a Box
  • I copied Sphere.mdl to Box.mdl in $HOME/Data/models
  • The viewport was still showing Box
  • Restarted the Editor and the scene, the viewport was showing a Sphere

It did also happened to me (I am on osx) but am not able to replicate it.
I tried again,
Coppied box.mdl -> x.mdl
Loaded static node for above x in editor, and it showed.
Coppied another model over x.mdl and the model changed.

@sabotage3d, Did you copy box from coredata to data folder?

Anyway I’ll try again and let me try replicate the same.

This looks like the directory watching not being correctly setup for resource directories that are added during runtime. I’ll look into it. Inside the Urho base folders (CoreData & Data) it should work.

The probable cause is this: when you try to pick files from whatever part of the harddisk, the editor doesn’t automatically add a resource path to the engine (which is required to actually load the file as a Urho resource.) This is actually for your protection in scene authoring: a scene file only stores relative resource names, and it has no concept of storing these “extra” paths, so if you proceeded to save a scene with files picked from anywhere on the HD, it wouldn’t load back correctly.

Rather, start with File -> Set Resource Path, or load a scene, which sets the path automatically. After that, picking files and hot-reloading them from within the path you’ve chosen, should work properly.

Thanks cadaver it works perfectly :slight_smile:
