Problem with Emission maps

Scripting Issues
1

I was learning how to use Emission maps (glow maps) in Panda3d .
I tried setting an Emission color and value in the principled BSDF node.
I tried baking a map in the emission channel before exporting.
none of them seemed to work for me.

Then I tried applying the baked map from code , it didnt get applied for .glb but did for .obj files .However it doesnt have a glow effect .

The code :

from direct.showbase.ShowBase import ShowBase
from panda3d.core import  TextureStage
from panda3d.core import AmbientLight
from panda3d.core import loadPrcFile



x = ShowBase()
x.set_background_color(0,0,0)
x.render.setShaderAuto()


alight = AmbientLight('alight')
alight.setColor((0, 0, 0, 1))
alnp = x.render.attachNewNode(alight)
x.render.setLight(alnp)

cube = x.loader.loadModel("CUBE.obj")
cube.reparent_to(x.render)
cube.setPos(0,-4,0)

ts = TextureStage("ts")
ts.setMode(TextureStage.MModulateGlow)
cube.setTexture(ts,x.loader.loadTexture("Baked_Light.png"))

x.run()

Your help is Appreciated

I’m not familiar with doing this myself, but looking at the manual, I note the following line:

In practice, though, things don’t really look like they’re glowing unless you apply a bloom filter to your scene.

(See the above-linked manual page for more detail.)
