I don't know why, but I can't play Aria Giovanni's card Halloween #480 with the fullscreen Halloween. Anybody has the same problem ?

Open the Halloween.scn file
almost at the bottom of the file look for these lines...

quad {
size: 1920, 1080
shader: fragment, sparkle.fsh
blend: true
}

change them to

// quad {
// size: 1920, 1080
// shader: fragment, sparkle.fsh
// blend: true
// }

put a double // at the beginning of each line to comment them out.

it's looks like your issue is with the sparkle shader.

Card #480 is All InOut, Pole, and Table clips. These are blocked in the Orig scene.
Open the Halloween.scn file

edit near the top..
clip {
border: 60
id: Clip
// deny: top, table, cage, pole, inout
deny: top, cage
}

Happy Halloween

In my file the double // are already programmed in and I'm stll getting the same problem mentioned by other posters in this thread.

@Wyld, you must have an earlier version of Halloween.scn
In the copy I received with the update for iS, the sparkle.fsh was already commented out by Totem.

The version I have also had the sparkle shader rem'd out.

I've just put it back - I rather like it.

Both versions work on my PC (Windows 10 + ATI/AMD Graphics card with the latest drivers).

just out of curiosity I enabled the sparkle shader section which was already commented out. It worked okay but I actually prefer the scene without the effect so will disable it again

Not sure what it is or is supposed to do but I renamed scattering.fsh to oldscattering.fsh and the scene now plays without the white block.

congratulations

Thank, who is the girl on the theme ?

we are not able to reproduce that white squares bug in the fullscreen here.
however I made a lighter version of the fullscreen, could you try to download this: https://www.istripper.com/software/scenes/Halloweenv2.zip pls ?
just unzip it in the screensaver folder, a second halloween screensaver should appear (with the subtitle 'trick or treat! v2).

hi and thanks,

installed it and its the same - white squares

but if I activate the 2 commented rows in the scaattering.fsh (thx to @dar2112v for the tip)

// sample *= illuminationDecay * weight;// + cos(u_Elapsed*1000.0)/500.0);
//gl_FragColor = vec4(0.0);

instead of the immo actviated onces the Scene is working - without the shining effect - but without the white squares

addition

sry mixed 2 things

in the original scene it's working with the 2 rows

in the Halloween2 scene become black screen when I change the 2 rows
but if I rename the file it's working also - but without the shining effect

Following Virt4B's last post I have looked at scatering.fsh. I see that in this shader gl_Fragcolor is not initialised and will have some random value when the shader is executed, but I am not sure how the use of multiple shaders affects this.

can you try with this:

for(int i=0; i < NUM_SAMPLES ; i++)
{
textCoo -= deltaTextCoord;
vec4 sample = texture2D(texture0, textCoo );

sample *= illuminationDecay * weight;
gl_FragColor += sample;

illuminationDecay *= decay;
}
gl_FragColor *= exposure;

the emu: that's a good question ....

Virt4B: can you try to add: gl_FragColor = vec4(0.0); just before this line: for(int i=0; i < NUM_SAMPLES ; i++) ?

Wow Bingo!!!

with this addition it is working!!! (gl_FragColor = vec4(0.0);)

great job - thanks to you @lezardo and @emu

now Halloween glows ;)

thanks a lot

excellent ! I will update the fullscreen right now :) thanks a lot guys

@lezardo: I added the line to the original halloween scene and even reactivated the sparkle.fsh and guess what. the scene works. but honestly i don't see a special effect other than the sparkle in bg.

If someone can tell me what the other shaders do that would be nice.
I am pretty curious about that.
for me the scene without the sparkle looks like just a girl dancing in front of a halloween background image.

the scene is now updated online, you can click on 'synchronize' it will redownload the scene.
@starryk, the scene looks like this: https://youtu.be/_jV1bHtNgwI

Open "Halloween.scn" and uncomment lines 84-88, then you will se the difference ;)

hm ok don't have these rays of light from the pumpkin here.. so what at least it doesn't look totally broken anymore
Edit: not sure what else you did @lezardo but it can't only be the initializing because i had done that already. But after synchronizing i now also see the rays of light.
Thanks a lot!

@lezardo, @Virt4B

When adapting the Shadertoy.com scenes for iStripper I have often encountered this sort of lack of initialisation, most often only affecting gl_Fragcolor.a.

Though the Glsl standard does not specify any initialisation for gl_Fragcolor but Shadertoy.com seems to initialise it to vec4 ( 0.0, 0.0, 0.0, 1.0 ). Some systems will explicitly initialise it, some not, and if they do it is system specific what they initialise it to. The worst case is systems that do not initiaise it, but where it is almost always "accidently" set to something sensible, but which may not do so after any software chane.

@lezardo
I synchronized also and the original and the Halloween2 scenes are working fine.
I really like this effect.

lot of thanks again to you

I made a mistake in my previous post, here is the corrected text (with a little extra explanation).

Though the Glsl standard does not specify any initialisation for gl_FragColor but Shadertoy.com seems to initialise it to vec4 ( 0.0, 0.0, 0.0, 0.0 ), but Shadertoy ignores the final value of gl_Fragcolor.a which effectively ***** it to be 1.0. Some systems will explicitly initialise gl_FragColor, some not, and if they do it is system specific what they initialise it to. The worst case is systems that do not initiaise it, but where it is almost always "accidently" set to something sensible, but which may not do so after any software chane.

I really like the new Halloween scene, looks fantastic.
