Actor not showing up

Scripting Issues
1

So I’m making third person camera and I use an actor to render the player but it’s hidden. Here is the code:

self.mannequin = Actor(‘player.glb’, {
‘walk’: ‘player.glb’})
self.mannequin.reparentTo(self.render)
self.mannequin.setTwoSided(True)
self.mannequin.loop(‘walk’)

Well, to start with the simplest: have you checked that your model loads properly in PView/a simple test-program?

Otherwise, where is your camera, and where is the mannequin-object being placed? Could it be that the mannequin-object is simply out of the camera’s sight? (For example, by being placed behind the camera, or by being placed too close to the camera.)

And finally, are you doing any particular setup to your camera–reparenting it to some other object, or applying state to it, or something like that…?

hmm are you sure .glb models work by default with the Actor class? for me, I have always first loaded the model using panda3d-gltf then supplied the nodepath into the actor class. This also means you no longer have to supply the animation file arguments.

# pip install panda3d-gltf
import gltf
model_np = gltf.load_model('player.glb')
self.mannequin = Actor(model_np)
self.mannequin.reparentTo(self.render)
self.mannequin.setTwoSided(True) # probably don't need this anymore
self.mannequin.loop(‘walk’)

This is usually the right way to do this as the direct Actor class automatically loads animations from nodes that have animation data.

If you install panda3d-gltf, it will register itself with Panda’s own Loader, allowing you to pass glb files directly into Actor. What won’t work is using pview, which is a C++ utility which doesn’t understand panda3d-gltf (which is a Python library), so you need to use gltf-viewer to preview it.

Most “hidden model” issues are usually a result of the camera being positioned incorrectly, either being inside the model in question or pointing away from it.
