I am sure everyone did come to the issue when you need to change the starting point of curve and that tilts your whole curve and you need to fix everything.
The same of course happens when I trim curve inside geometry nodes.
But i do not want random tilting when i am trimming my curve.
One solution is to not trim it at all and just make it seems like you are trimming it by setting radius to 0 on some spots.
But as my curve is quiet difficult i can not let whole curve even with 0 scale be loaded.
So i tried to set normal to only Z but that makes wierd overrotations when the curve is probably facing Z.
So i tried to make the curve normal only Z just on that first point of curve. That does not work as the set curve normal works only for whole curve.
1) So my question is probably can someone come to a idea how could I negate the newly made rotation.*
2) Or if I can make guiding curve which would not have loaded that difficult mesh and somehow copy the tilt from this curve.*
I can not think of another type of a solution but if you find one i would love to try. I think this problem has many people but they are not trying to animate trimmed non circular shape curve with texture
here is file which has all of the distortion that will be aplied on the curve
Here is an example of a curve tilting as it is trimmed:
