how ca i do this ??

[jisun]

I want to make particles and lines that flow down the stairs. The problem cannot be solved in the 90 degree bend.

make of those stairs VDB and use this on Pop wrangle (input 2 ) on first points that you want to use)

float volSample = volumesample(1,0,@P);
vector volGrad = normalize(volumegradient(1,0,@P));

@P -= volGrad * volSample;//adjust Position

@v += @force * @Timeinc;//Force to V
@force = 0;//Force to be 0

vector vVertical = volGrad * dot(@v, volGrad);
vector vHorizontal = @v - vVertical;
@v = vHorizontal;

계단 VDB를 만들고 사용하려는 첫 번째 지점의 Pop wangle(i nput 2)에서 이것을 사용하십시오.

 

It's hard to understand.
Can I ask you to share the file? Thank you.
