I'm trying to recreate the CHOP Lag / Overshoot / Smooth in vex. Trying to add some features to a little sequential value generator i'm feeding to animated geos / cameras to automate animatino.

Script looks like that, but it's all a bit abrupt, the ease in and out function is not working as expected, I'd love to smooth things in and out with controls. Any pointers welcome.

Cheers.

Struggling with the gridmarkets install, it keeps breaking, works for a bit, then can't find the "lib" folder which is perfectly installed in the otls folder, vairables at set properly, i'm getting super confused. THis stuff is quite unreliable. Any idea how to fix this stuff please?



thanks a lot,

A.

Just taking a shortcut here. I'm having a problem with gridmarkets submitter not finding the "lib". It was working fine, i submitted jobs, then suddenly it just won't find the grodmarkets_lib, which is perfectly installed in the proper otls folder. I had that yesterday and somehow managed to fix that by installing/reinstalling and all buncha of manual clean up and sequence of stuff i can't recall. But it worked again... and bam, today again the same crap, it just won't find the lib. Have you ever had that issue? Their crappy enjoy lunacher app does not let you choose the location of installation of their files so god knows what it does. But it appears it installs in some obscur users folder that has nothing to do with the main one.

Any pointers welcome, this stuff is a real pain.

Cheers,

A.
