I don't understand development, I just put forward some ideas
The MAPPING operator can convert floating-point values to values in the "U" axis of "UVW", so is it feasible to reverse the value of particles in the "U" axis of the object's closest vertex?
For example, aligning the Z-axis of particles with the object's normal and aligning the Y-axis with the "U" axis in the object's "UVW". Is this achieved?
I can't say exactly what kind of things I can do!
Just like the "tyConform" modifier's "UVW align" mode, this is a very interesting feature
The particle alignment I mentioned to UVW, if equipped with this function, can be said to achieve true customization by controlling the direction of the particles. That is to say, I can adjust the UV's sorting layout at any time, making it easy for the particles to lean in any direction
