WIP - TurnTable Object Node [Houdini Utility] Jan. 5, 2023, 5:02 a.m.

Copy the file into the HDA folder of your project. Then go to menu Assets > install asset library > pick the hda file

Coordinates rounding? Dec. 3, 2022, 1:08 p.m.

Well 2.5 was just an example. Perhaps this happen only on numbers that Aizatulin was telling about : 2.1 2.6 0.1 ...
But I still don't understand why these numbers don't stay the same as I entered. Even if I don't manipulate the handles, 2.1 turns to 2.1000000000000001, which is not the same VALUE.
Same thing with transforms at 0 that turn to microscopic values.

Hey Aizatulin
Well no, in my case 2.5 is NOT the result of a calculation, it's just values that I type in, on some objects, in the transform tab at the /obj level, or in the base node in the geometry level. At the beginning all is fine and when I type "2.5" I can see "2.5".
Then when I go back to the same node, the value is converted to "2.499999999".
So the problem is not even a rounding problem, 2.499999999 is lower than 2.5, so the real problem is that the value is CHANGED.
The same happens with rotations. Even if I don't rotate an object , when its transform is 0, after a while Houdini keeps putting things like "-1.73472e-18". These values are so small they're equivalent to 0, but why does Houdini replaces "0" by "-1.73472e-18"?
THIS is what I don't understand, and no technical math page will put my mind at ease about this. I still think it's a bug.
