I made the chain in the same style as my previous example it's a bit more complicated, since the section has an “H” shape all the points are doubled to give angular edges (compared to normals) of course it's fake, a simple texture scrolling, but it's light otherwise, to make it clean, you have to us...

a few small changes note that the alpharate parameter of ParticleColorFader must be consistent with ParticleTimeToLive if duration is 2 seconds, alpha must lose 0.5 per second InitEngine3D() InitSprite() OpenWindow(0, 0, 0, 640, 480, "Cube example", #PB_Window_SystemMenu | #PB_Window_Scree...

indeed, another error in the doc
(curiously, in the French version it's ok)

the latest version (but that's not the problem)

have you pressed the space bar ?

you're using values that are far too large! it's the x parameter you need to modify if you have a 60Hz framerate, a 1/60 offset will shift the length of your texture every second I've made a few small changes to your code note: startdrawing(screenoutput()) isn't very good (very slow), better use a s...

rotatematerial has no place here scalematerial: - the x parameter is the total length of your belt divided by the number of repetitions of the texture you want. (line 79 of my example) - the y parameter must be 1 :no scale change in y axe scrollmaterial: - the x parameter defines the offset or its s...

not easy to make progress
do you see it with Fred?

to animate the belts independently, you need to use one material per belt and adjust speed with scrollmaterial

a video for me, great!
(after viewing, I'm a bit disappointed, I was thinking of a documentary on my life and work )

since v6, the list of authorized constants is displayed for function Arguments, too bad it requires typing "#pb_" (especially for beginners)

I'm not sure I understand is this what you want? InitEngine3D():InitSprite():InitKeyboard():InitMouse() ExamineDesktops() OpenWindow(0, 0,0, DesktopWidth(0)*0.8,DesktopHeight(0)*0.8, "CreateShader - [Esc] quit",#PB_Window_ScreenCentered) OpenWindowedScreen(WindowID(0), 0, 0, WindowWidth(0)...

It works with several PB versions

did you search for "engine3D.dll" files on your computer ?

@Michel Vogel
it's just a technical demo, I didn't try to make something pretty!

@Psychophanta
don't you think it'd be easier to fix your problem than to adapt all the 3D code just for you?
did you search for "engine3D.dll" files on your computer ?

@Psychophanta as I've already told you, it seems to me that it is clear, InitEngine3D loads an old DLL search for "engine3D.dll" on your computer, and see if you have an old version maybe in the folder where unsaved code is executed (look in the preferences) you can also try saving the cod...

[EDIT 28/03/24]
adapted for PB6 (no scripting required, shaders are created in code)

effectively
I updated the code for v2
now it should be ok
