Actor glft light/texture issue

[volodyaleo]

I have read faq and added Actor.

But models are black. The model can be found here.

        self.actor = Actor(model)
        self.actor.reparent_to(self)
        self.actor.setScale((scale * (1 / model_width), scale * (1 / model_height), scale * (1 / model_width)))
        if model_rotation_correction:
            self.actor.setH(model_rotation_correction)
        if model_y:
            self.actor.setPos(0, model_y, 0)

Can someone help me? What the reason might be?

You're lucky, at least gltf works. When i tried to use gltf, all i've got is a path error, no matter how i exported and place model :D

For Actor it's better to use .egg format of models, works 100%.

I know this is an old issue, but have you tried setting the texture stage? Sometimes messing with flipped_faces or double_sided will help, see this class for an example on setting the texture stage:

from direct.actor import Actor
#from direct.actor.Actor import Actor
from panda3d.core import Shader as psha
from panda3d.core import TextureStage, TexGenAttrib
class Human(Entity):
   def __init__(self):
       super().__init__(parent=scene, shader=basic_lighting_shader)
       #super().__init__(parent=scene, shader=basic_lighting_shader, flipped_faces=False, double_sided=True)
       
       # https://docs.panda3d.org/1.10/python/programming/models-and-actors/actor-animations
       
       self.actor = Actor.Actor("models/CatPilot.gltf")
       
       # for physics
       self.model = self.actor
       
       tex = loader.loadTexture('textures/CatPilot.png')
       self.actor.setTexture(self.actor.find_texture_stage('*'), tex, 1)
       
       # CatPilot model comes with three textures (pbr, emission and normal)
       # When loading, it's necessary to change the existant texture stage
       ####ts = TextureStage('ts')
       #ts = self.actor.find_texture_stage('0')
       #ts.setMode(TextureStage.MAdd)
       #self.actor.setTexture(ts, tex, 1)
       
       # https://discourse.panda3d.org/t/settexture-makes-model-black/28620/7
       #print('***DEBUG ', self.actor.findAllTextures())
       #oldTexture = self.actor.findTexture('pbr-fallback')
       #newTexture = loader.loadTexture('textures/CatPilot.png')
       #self.actor.replaceTexture(oldTexture, newTexture)
       
       #self.actor.setColorScale(1, 0, 0, 1) # set to color red
       
       self.actor.reparentTo(self)
       
       #print('======= ANIM DICT ======')
       #print(self.actor._Actor__animControlDict.get('common').get('modelRoot'))
       #{'PutOnGogglesBlink': Actor.AnimDef(None), 'WalkBlink': Actor.AnimDef(None), 'Cheer': Actor.AnimDef(None), 'Default': Actor.AnimDef(None), 'FlyingPlane': Actor.AnimDef(None), 'DefaultAnim': Actor.AnimDef(None), 'PutOnGoggles': Actor.AnimDef(None), 'Run': Actor.AnimDef(None), 'GogglesOn': Actor.AnimDef(None), 'Walk': Actor.AnimDef(None)}
       
       #self.model_bounds = self.actor.bounds
       #self.actor.showTightBounds()
       
       action = lambda: print('OW!')
       self.on_click = action
       
       self.scale = (1, 1, 1)
       self.rotation = (0, 0, 0)
       self.color = color.white
       self.position = (1, 2, 1)
       self.collider = 'box'
       self.gravity = 1
       
       MeshCollider(world, self, mass=1)
