caching substeps Nov. 23, 2020, 4 p.m.


Caching sub steps using the file cache node doesn't seem like a full proof solution if you want to cache sub steps from such data as a particle sim, etc. For example, I wanted to cache (bgeo) of a particle simulation with 5 substeps. If you look at my photo, you can see that I get frames like 2.200000000000000001 instead of 2.2. I tried everything, I tried setting the substeps to 5, I tried setting the increment to things such as (0.2 or 1/5) but nothing works. Some times it works, sometimes it does not (meaning some frames get the right number and some get long decimals). If I am only doing 2 substeps, it usually works fine. The more substeps you add, it starts to become less stable. Even the documentation says, “The disadvantage of using $FF is possible binary-to-decimal arithmetic errors causing $FF to have a value like 31.99999.” So does that mean there is no way to guarantee 100% success rate when caching substeps? If so, that seems like something that would be worth fixing.


gas equalize volume unstable with large objects Nov. 6, 2020, 4:06 p.m.

hmm, found a fix. Bigger objects need more substeps.

Obnoxious moving windows bug Nov. 4, 2020, 1:48 p.m.

You don't have to close the program, if you your mouse to select the very bottom of the window until the resize arrow comes up, then resize it, the top menu will automatically pop down into the right spot. Or after opening the window you can hit alt + space then hit m and you can move the window around.
