You can see for yourself the json files being exported if you unzip the file speckle creates when exporting stuff.
A rough breakdown of the files exported:
static.json- contains the static geometry (objects that do not change if the sliders move)
params.json- contains the metadata, basically the secret sauce that makes the sliders, performance evaluation cirteria, etc.
xx,yy,zz.json- these are named after each combination of input slider values. They contain the dynamic geometry.
Any questions shoot @idid
