How to make particle face camera? - linkinb - 12-10-2021
hi, I want to increase the size of the ends of my rope as shown below.
[attachment=1129]
My code is as follows.
Code:
var active_Rope = rope;
if (active_Rope == null || solver == null)
return;
// index of the first particle in the actor:
int FirstParticle = 0;
int LastParticle = active_Rope.activeParticleCount - 1;
int SecondParticle = 1;
int SecondLastParticle = active_Rope.activeParticleCount - 2;
Vector3 EndsShape = Vector3.one;
solver.principalRadii[active_Rope.solverIndices[FirstParticle]] = EndsShape * RopeEndsThickness;
solver.principalRadii[active_Rope.solverIndices[LastParticle]] = EndsShape * RopeEndsThickness;
solver.principalRadii[active_Rope.solverIndices[SecondParticle]] = EndsShape * RopePreEndsThickness;
solver.principalRadii[active_Rope.solverIndices[SecondLastParticle]] = EndsShape * RopePreEndsThickness;While this scales up the particle, the particle does not scale uniformly as shown in the image above.
My rope is rendered on a secondary camera that using a culling mask and camera clear flags set to "Depth Only", so that my ropes always render infront of all other objects.
goal is that I want the ends of the rope to be scaled up and face the camera always, so it looks clear and uniform. (As shown in the above image)
How can I achieve that effect?

Hi!
I’m not sure I understand the question, the image shows 3 ends all uniformly scaled. Particles in a rope are always spherical.
For the same reason, it makes no sense to make a particle “face the camera”, since they’re radially symmetric: no matter how they’re facing, they will look the same.
Keep in mind that ropes do not model orientation, (unlike rods) so you can’t explicitly choose the orientation of a single particle.
