@ET: Sorry buddy. I guess I should have made it a little more clear. Your last scene was not what I was talking about. The shaders all work just fine 😄

My  response was  to your and @Dano's discussion about mixing clip types in a single model scene, ie, swing clips at the top and say, sitting clips at the bottom. This was what I was talking about, trying all kinds of code to get it to work, so far, without any joy 😢

@Beast: I've gone thru all of those places you mentioned over the last few weeks and slowly, I am learning. Bear with me tho as I'm still not sure which language VG is using. It doesn't look anything like GLSL shader code. (Or GL_ES). Yes, some of the same vocabulary is used of course as they must be compatible.
What I and it appears others are asking for is a VG specific vocabulary and structure. Is it the Team's own language?
Eg: From @lezardo's ShadowBlob.scn file:

framebuffer {                                  //This I underdstand
 id: Fbo                                           //This I understand
 source: Clip                                   //This I understand
 shader: fragment, Blur.fsh            //This I understand
 uniform: orientation, vec2, 1, 0     // Orientation is fairly obvious and vec2 I assume is the x.y of the screen but
                                                          the 1, 0 afterwards ???   Is that a hotspot?     
 uniform: changeColor, int, 0         // Same here. Int is integer (whole number) but why is it there and the '0'
                                                         after it ??? Does int,0 mean full strength colors and random?
}

Great to have new stuff to play with but would be nice to know exactly what each NEW line of code refers to and what it actually does and why 😐

We (or at least I) can spend ages trying to figure out how to do something or what something does by trial and error.  A help page saying something along the lines of:
This is a list of vocabulary showing when , where and how to use them.
This chunk of code does this or that. If you want to do this, then you need to do that. Altering these parameters will do this or that.

Digging around all over the place, including downloaded code from others is extremely time consuming although fun at times 😉  and does help one to learn.
My point is this. I'm trying to learn two new languages at the same time... Without a dictionary or verb table for one of them. GLSL is fairly well documented but VG code is ... Not in print yet. So do we still have to keep on learning by studying others' code or is there someone here who knows it all AND has the time to build a coding language page?

Edit: Formatting errors not my fault :(
