Set texture and object become black

[HeiMD]

Hi,

I imported the glb file, it looks very nice. What I want to do is to place one more texture on the object, but the object always black. Did I missing any setting?

Left side is the original one and right side is after setTexture():

class MyApp(ShowBase):

    def __init__(self):
        ShowBase.__init__(self)
        simplepbr.init()
        dlight = DirectionalLight('my dlight')
        dlnp = self.render.attachNewNode(dlight)

        self.frame = self.loader.loadModel("scene/frame.glb")
        self.frame.setPos(0,1,1)
        self.frame.setScale(0.5, 0.5, 0.5)
        self.frame.setHpr(0,0,0)
        self.frame.reparentTo(self.render)
        self.frame.setLight(dlnp)

        self.frame2 = self.loader.loadModel("scene/frame.glb")
        self.frame2.setPos(1.5,1,1)
        self.frame2.setScale(0.5, 0.5, 0.5)
        self.frame2.setHpr(0,0,0)
        self.frame2.reparentTo(self.render)
        self.frame2.setLight(dlnp)

        art = self.loader.loadTexture('scene/art/star.png')
        ts = TextureStage('ts')
        self.frame.setTexture(ts, art)

app = MyApp()
app.run()

Maybe this will help.

Using simplepbr renders native blender geometry and textures black

Hello guys, I have a problem with native (non blender-exported) geometry showing up pitch black. When transporting my blender models to Panda3D, I would like to avoid egg-files in favor of the more native export of glTF files. After import of the simplepbr module, the glTF models CAN be loaded (without error), and after calling it’s .init method in the Base subclass constructor, the textures even look correct. The problem is that if I call the .init method, the geometry generated by panda3d s…

In short, you need to customize the material.

Hi, and welcome!

It seems that loaded models don’t use the default UV (texture coordinate) set, but rather one that is specifically named "0".

So perhaps it will work better when you set up your custom TextureStage to use that particular UV set:

        ts.set_texcoord_name("0")
