If you create a ParticleEmitter with the Orientation property set to VelocityPerpendicular, setting the speed to 0 will cause nothing to ever render, even with acceleration.
In this picture, there are 3 ParticleEmitters all with VelocityPerpendicular orientation, so the particles should face upwards
That’s what I usually do, but it’s important for acceleration to have the same effect since it can be in world space while speed is always relative to the ParticleEmitter’s parent.
I’m hoping this gets fixed, a tad-bit tedious to always set the speed to 0.01 instead of just not having it move at all. Still won’t render when I set it to zero.
The issue still persists with VelocityParallel & VelocityPerpendicular.
Even with a Rate of 100 for a particle with inf lifetime, it’ll never emit anything with a Speed of 0 regardless of the value of any other property.
Changing only the Speed to 0.001 will instantly start emitting the particle as intended.
Please also refer to the reply above mine for the new issue, it’s a major inconvenience for combat systems using vfx like sword slashes.
