im trying to assign ‘flatMaterial’ to the stickNode node. it doesnt do anything though…

from pandac.PandaModules import *

import direct.directbase.DirectStart


#Task to move the camera
def SpinCameraTask(task):
    move = 25*task.time
    angleradians = move * (math.pi / 180.0)

    base.camera.setPos(20*(math.sin(angleradians)),-20*(math.cos(angleradians)),3)
    base.camera.setHpr(move, 0, 0)
    return Task.cont

taskMgr.add(SpinCameraTask, "SpinCameraTask")




stickActor = Actor.Actor("models/box2anim.egg",{
	"rup":"models/box2anim-rup.egg",
	"lup":"models/box2anim-lup.egg",
	})
	
stickActor.setScale(1,1,1)
stickActor.setPos(0,0,0)
stickActor.makeSubpart("left", ["l0","l1"])
stickActor.makeSubpart("right", ["r0","r1"])
stickActor.loop("rup", partName="right")
stickActor.loop("lup", partName="left")

stickNode = render.attachNewNode("stickNode")
stickActor.instanceTo(stickNode)
stickNode.setPos(0,0,0)
stickNode.reparentTo(render)

flatMaterial = Material()
flatMaterial.setShininess(15)
flatMaterial.setAmbient(VBase4(0,0,1,1))
flatMaterial.setDiffuse(VBase4(0,0,1,1))
stickNode.setMaterial(flatMaterial)

plight = PointLight('plight')
plight.setColor(VBase4(0.2, 0.2, 0.2, 1))
plight.setAttenuation(Point3(0, 0, 0.005))
plnp = render.attachNewNode(plight)
plnp.setPos(0, -2, 15)



render.setAntialias(AntialiasAttrib.MAuto)
render.setLight(plnp)

What happens if you set an override?

stickNode.setMaterial(flatMaterial, 1)

it works then.

what is an overwrite/what does it do. why didnt it work without it?

added:

also…the shininess doesnt seem to do anything ( i put it up high and still nothing), and my light is still fairly dull at an Attenuation of 0, 0, 0.005. very dull unfact. :S

can you tell me how i can modify those values to have a normal light and see the effects of the shininess? :confused:

Well, try enabling per-pixel lighting using setShaderAuto() - does that make the shininess show up?

The override is to override the material that might have been applied to a subnode.

5

i had no other materials applied though.

and no, that doesnt make it work either (shininess 0 is the same as 100 :frowning: )

Thanks for this tip. It solved a problem I was having with my lighting. I think it should be mentioned somewhere on the the manuals lighting page http://www.panda3d.org/manual/index.php/Lighting

are you able to get shinniness working? (if so, gimme source please?) :neutral_face:

Sorry no, Im not using shininess in my texture, my problem was lighting on a sphere I had looked real choppy and blocky until I used setShaderAuto() on it
