Is there a program(preferably free) that can create a big .png for credits after loading a text file?Like it would be great if it could count the scroll speed depending on the bgm lenght.
What im thinking is to load it into Panda and scroll it down.Dunno if its the best way.

I use the GIMP to create a large image, put it on an OnscreenImage, set the Z position to a low value, and move it upwards.

Alternatively, if you can't create a big PNG, create multiple smaller ones -- and multiple OnscreenImages, then set an offset on each, and reparent them to a bigger dummy node. Then, you can flatten that dummy node and move it upwards.

why not use the panda3d TextNode and just scroll the text with an interval?

And add some fading :
Code:
from pandac.PandaModules import *
from direct.showbase.DirectObject import DirectObject
from direct.gui.DirectGui import *
import direct.directbase.DirectStart
import sys, string, math

globalClock.setMode(ClockObject.MSlave)

def cycleAlpha():
    global VARIANT
    VARIANT=(VARIANT+1)%len(images)
    tex.load(images[VARIANT])

VARIANT=0
images=[]

#_____TOP & BOTTOM FADE
img=PNMImage(32,32)
img.addAlpha()
img.fill(1)
img.alphaFill(1)
for x in range(img.getXSize()):
    for y in range(img.getYSize()):
        img.setAlpha(x,y,-.2+2.5*math.sin(math.pi*y/img.getYSize()))
images.append(img)
#_____SPOTLIGHT
img=PNMImage(32,32)
img.addAlpha()
img.renderSpot(Vec4D(1,1,1,1),Vec4D(1,1,1,0),.6,1)
images.append(img)
#_____DOUGHNUT o_0
img1=PNMImage()
img1.copyFrom(img)
img2=PNMImage(32,32)
img2.addAlpha()
img2.renderSpot(Vec4D(1,1,1,0),Vec4D(1,1,1,1),.1,.4)
img1.darkenSubImage(img2,0,0,0,0)
images.append(img1)

tex=Texture()
tex.load(images[VARIANT])
tex.setWrapU(Texture.WMClamp)
tex.setWrapV(Texture.WMClamp)


# background
osi=OnscreenImage('maps/4map.rgb',parent=render2d)
osi.setColor(.2,.2,.2,1)

# alpha preview
CM=CardMaker('')
card=base.a2dBottomLeft.attachNewNode(CM.generate())
card.setScale(.25)
card.setTexture(tex)
card.setTransparency(1)
ost=OnscreenText(parent=base.a2dBottomLeft, font=loader.loadFont('cmss12'),
   text='press\nSPACE\nto cycle', fg=(0,0,0,1),shadow=(1,1,1,1), scale=.045)
NodePath(ost).setPos(card.getBounds().getCenter()-ost.getBounds().getCenter())

dummyParent=NodePath('')
textParent=dummyParent.attachNewNode('')
textParent.setDepthTest(0)
textParent.setDepthWrite(0)

# THE CREDITS TEXT
ost = OnscreenText(parent=textParent, font=loader.loadFont('cmss12'),
   text='CREDITS\n\n'+'\n'.join([c*30 for c in string.ascii_letters]),
   fg=(1,1,1,1),scale=.065)
ost.setP(-90)
ost.flattenLight()

ts=TextureStage('')
textParent.setTexGen(ts,TexGenAttrib.MWorldPosition)
textParent.setTexScale(ts,.5,.5)
textParent.setTexOffset(ts,.5,.5)
textParent.setTexture(ts,tex)
b3=textParent.getTightBounds()
dims=b3[1]-b3[0]
textParent.posInterval(50,Point3(0,dims[1]+2,0),Point3(0,-1.05,0)).start()

VPcam = Camera('vpcam')
VPcam.copyLens(base.cam2d.node().getLens())
VPcamNP = dummyParent.attachNewNode(VPcam)
VPcamNP.setP(-90)
dr=base.win.makeDisplayRegion()
dr.setCamera(VPcamNP)
dr.setSort(1000)


do=DirectObject()
do.accept('space',cycleAlpha)
do.accept('escape',sys.exit)
globalClock.setMode(ClockObject.MNormal)
run()
