i might try 88 particle generators… each particle system would have the birthrate line to one of the checkboxes. when checked, the emitter would emit enough particles to create a line, when not checked, it would be zero.
an expression like this on birthrate could work:
chk = thisComp.layer("activeLeftHand").effect("22")("Checkbox");
if ( chk == true ) 100 else 0;
change “100” to a value that would create a steady line of particles.Kevin Camp

you could use a particle system to create a grass field and then push a 3d camera thru it. you’ll likely have issues with the camera moving thru a blade/stalk of grass, though.
to quickly demonstrate, create a new comp, and use the pen tool to quickly make a simple blade of grass (like a long skin triangle with 3 clicks).
- make the fill color solid green and then hide that layer.
- create a new solid and add Particle World.
- in the particle settings, set the particle type to texture quad polygon then set the texture to your grass shape layer. increase the birth and death size to 1 or 2 (maybe larger), rotation speed to zero and initial rotation to 15-30 or so. also set the max opacity to 100 and make the opacity map a straight line at the top of the graph (by default it is ramped at the left and right, make that a solid dark gray rectangle)
- in the physics settings set velocity and gravity to zero.
- in the producer settings set radius x and z to 1 or so.
- at the top of the effect, set the longevity to the length of the comp and keyframe the birth rate to go from 200 or so to 0 over on frame.
you should have a simple field of grass.
now you can add a single node camera and animate it along it’s z axis to move thru the grass.
a particle system like Particular would also allow you to create a spherical field that could move with the camera to push grass out of the way of the camera…

it is interesting that OpenCL performance dropped with the new version of ae…
it’s my understanding that apple writes the drivers of the OEM GPUs, and those may get updated with OS updates, so it is possible that high sierra could help, but i wouldn’t hold my breath.
my guess would be that adobe will have some updates that may improve performance with more GPUs.

have you tried importing the corrupt project into a new project

this might work for you…
add the gradient ramp effect (you only get 2 colors, i’d keep them back and white, but you can change the location of the end points for angle, and ramp shape).
then add colorama to colorize the ramp. the default will give you a smooth rainbow or colors. twirl down the output cycle and near the bottom of those settings uncheck the interpolate palette. the smooth rainbow will be replaced with solid bands of 6 rainbow colors. now you’d just need to change the output color cycle to the colors that you need (which can be tricker than you’d think)
this isn’t an ideal workflow, but it may work for you.

this seems a little clunky, but i think it will work:
s = " " + effect("Slider Control")("Slider").value;
s.split(" ")[1].length;
essentially you need to get the number value to be a text string rather than a number, then you can use length to return the number of characters (minus the space that we added to convert the slider value to a string)Kevin Camp

light trail effects are often made with a particle system. you animate the producer/emitter position but set the particle velocity to zero so the producer/emitter leaves a trail of particles.
as an example, create a solid and add cc particle systems ii to the solid. option-click (osx), alt-click (win) the producer’s position property and type this little expression: wiggle(1, 400) (this is just to quickly animate movement for this example, you would ultimately link this to you moving object). set the x and y radius for the producer to 0.
in physics, set velocity and gravity to 0.
in particle, set type to faded sphere, birth size to .5 and death size to 0.
if you ram preview that, you should start to see a light streak-like animation. increasing the birth rate will help smooth it out and changing the longevity will change the length of the streak.
changing the transfer mode in the particle settings to screen or add can make it see more glow-like.
i’d need to se an example of the tunnel effect that you mentioned to help with that.

if you are looking recombine the red, green and blue layers back to form the full color image, set the blending modes of the upper two layers to ‘add’ in Ae or ‘linear dodge’ in Ps.
here’s tutorial that separates a layer into RGB layers and then recombines them (it’s a long tutorial, but the process you’re looking for is covered in the first 5 minutes or so):

in the character palette it looks like you have a 30 pixel white outline set for your font.
to turn off the outline, go to the character palette, and where you can see the color selection square (currently white square in the upper-right corner of the palette), click the outline color and then select ‘none’ (the small square with the red diagonal line across it).

if your looking for mpeg streamclip, it’s here (free):
https://www.squared5.com/svideo/mpeg-streamclip-win.htmli would render the 10000×96 comp as quicktime, photo-jpeg (but lossless is fine too), bring that into streamclip and choose file>export mpeg-4. you can set the settings per delivery specs.
i have not tried to export a 10000 px wide file from streamclip, but it would be easy for you to try. after export, bring it back into ae too see if it maintained the size.
adobe media encoder can likely do the same, but i’ve been using streamclip for too long to switch to it…
