simple split/filter by text? April 10, 2021, 9:47 p.m.

I used the labs 'filter by value', but then I still had to use two of them to get the functionality of a split, and even then its more difficult than it needs to be because the operation mode needs to 'contains' (it fails on 'equal to' because its a string and not a number), and its another gotcha of do you or don't you use an @, or backticks, or make sure to spell the attribute right because it doesn't list the attributes in a combo box etc... too many ways to shoot yourself in the foot.

Looks like this if you're curious. I love that labs is trying to solve this problem, but it shouldn't be up to labs. Tops attribute discovery/comparison/manipulation should be core to tops and idiot-proof (cos I'm a high functioning idiot):

Insert a point in a curve knowing its uvw April 10, 2021, 12:59 a.m.

carve sop? it's not hugely procedural (its a pain to control it from attributes, drive different curves with different cut points), but at a basic level does what you're asking.

frames ok during rendering, turn bad on save April 7, 2021, 7:18 p.m.

Only juuuust getting started with rendering in lops with other renderers myself, but just curious, are you able to move to 18.5? Lops in 18.0 was pretty raw, might be worth testing in a more recent build.

Also you might get more answers if you can reduce the issue down to simple repro hip. If nothing else you'll be more likely to get 'me too' posts which can help build your case with support.
