Standing ovation @Wyldanimal.
It works like a charm now.!! I can also see where I went wrong.
Very much obliged for yours & others helps here maestros 👍

If you want to give yourself a fit change the multiplier to 120 :D

Shorter, slightly more efficient, and giving equal time to each background rather than biasing it towards one or the other, would be

uniform sampler2D bg0;
uniform sampler2D bg1;

void main(void)
{
gl_FragColor = (sin(u_Elapsed*0.1)>0.0) ? texture2D(bg0,vTexCoord.xy) : texture2D(bg1,vTexCoord.xy);
}

I have not tested it, but I can't see any typos.

This version, however, can not be so easily generalised as @z22's and @wyldanimal's suggestion.

Well, the discard and stack layers in a 3d camera scene kind of works but i am getting a gray line around each layer for some reason. Any ideas as to why?

there are no light sources so it's not a shadow.

Is it, perhaps, the result of feathering or antialiasing that blends the edges of the image with transparency to avoid jaggies? Maybe your processing has exagerated this if it is present in the first place.

only thing the shaders are doing is discarding if out of bounds eg < 0.6 | > 0.71

I probably don't need the > parts really, was just trying to fix one type of error.

I think it's something the the 3d camera is doing for some reason. It may work with a 2d camera but will have to figure out the x offsets

@Emu, thanks lots for the alternate swap code.
Timing background changes accurately with some scenes
like the gaming ones is going to become critical.
Having settings as uniforms, is going to be extra good
to manage swaps too 👍.

Changed it over to a 2d camera and the gray lines are gone... weird..

Working version

may need to increase the seperation a bit more.
might add more layers.

It appears to be the some kind of scaling that caused the gray outlines because if i have scale: 0.5, 1.0 in the camera 2d version i get the gray lines again....ffs

easy fix though, just moved the scale to the clip in the original framebuffer.

I wonder....

If i can move all the discards into one shader by setting alpha to 0 if the "if" is triggered rather than discarding and offsetting the layers in there before combining them for output. May be able to make a progressive scan 3d version by using the if else *****/flop we have been discussing and setting it so it swaps every frame. so "u_elapsed*60"

even without progressive scan it would make it easyier for others to use if it was just 2 shaders and 2 sprites.

Will give it a go later on...

The 'if else' swap would need to be set for even timing perhaps or it might flicker some.
Nice going @Z22

Yeh, when i was messing with it before in the TLJ mirror expriment, i sometime had odd extra frames

That does sound like a very simple anti-jaggies mechanism that results in blending between neighbouring pixels, some of which are transparent, after scaling.

Absolutely.! The less shaders used, and the more uniforms declared, the more portable it will be for existing .scn's to become mods. 👍

@z22 the existing grey lines to me look very similar to the first time you played with the wet skin look.
the boundaries came up then like contour lines.

@TE yeh, something like that anyway. know to avoid it now.

@ET I think with the wet look shader it was just down to how bright the overlay was rather than an unexpected error as this was. In this case it appears to be another annoyance that is out of our control... 2d camera doesn't have the same problem unless i do scaling in the camera node so it's easy to avoid.

hmm, how to assemble 19 layers in a shader.... ponder...

may work...

if((Girl19.a) > 0)
{
gl_FragColor = vec4 (Girl19.r, Girl19.g, Girl19.b , Girl19.a );
)

if((Girl18.a) > 0 && (Girl19.a) == 0)
{
gl_FragColor = vec4 (Girl18.r, Girl18.g, Girl18.b , Girl18.a );
)

if((Girl17.a) > 0 && (Girl18.a) == 0 && (Girl19.a) == 0)
{
gl_FragColor = vec4 (Girl17.r, Girl17.g, Girl17.b , Girl17.a );
)

ect, ect...

@EverthangForever - for swapping backgrounds according to some schedule you could use one or more of the "Pulse_RGBA" shaders from my library. They only act on a single image but you could have a stack of sprites and control each of their opacities using the shaders - much like using animate: for opacity but much more flexible. These shaders allow you to set up a schedule of "pulses" for the R,G,B and A components, the schedule comprises an initial quiescent phase with no pulses, a phase where the pulses occur cyclicaly and a final phase quiecent phase. Each phase is optional. The pulses can be sharp edges or the edges may be softer.

Everything is controlled via uniforms that you can declare in the .scn file.

in the examples the pulses are affecting the overall brightness by pulsing the R,G and B components, but you would want to have them act on the A channel instead (or as well if you wanted a fade to/from black as well as changing the opacity). This is controllable via the uniforms declared in the .scn file.

They can be a bit heavy on the GPU due to their flexibility so at some point I intend to create simplified versions that, for example, only do sharp pulses or only do soft pulses or only act on the opacitycahnnel rather than have everything fully configurable at run time.

@Z22 woohoo thanks 👌

@Theemu, thanks a lot, If peeps are looking for TheEmu's pulse shaders
you can find them in his 0000 - Basics/Shaders/TheEmuLib.Scheduling directory
Their documentation is in rem lines in the various shaders

Think i have some errors in there somewhere... it shouldn't have that line near the edge.

Think it's my cuttoffs are starting to low(0.05) so none of the girl gets clipped out for the first few layers.
