Turbulize particle velocity -- some particles get stuck
Turbulize particle velocity -- some particles get stuck
I've noticed that every time I use that node, there's always groups of particles that hang in the air, while other do their thing and move around correctly. Does anyone know why this happens?
Re: Turbulize particle velocity -- some particles get stuck
yes its a known problem with strong turbulance that particles get stuck in 'valleys' (not just in XSI ) try curl noise instead, whilst a bit more setup I do believe that is what it was designed for and you will not get particles 'stuck' unless there is some other logic in your tree making them 'stick' in the air

Re: Turbulize particle velocity -- some particles get stuck
One thing that has confused me about the turbulise node, in the past, is that the values range from -1 to 1 rather than 0 to 1 as I'd assumed, causing some strange behaviour.
I'm not saying this is the reason behind your problem but its worth bearing in mind anyway.

I like Curl Noise, but when I use modulate by noise to activate the effect, it will only occur inside the area of the null.Tekano wrote:yes its a known problem with strong turbulance that particles get stuck in 'valleys' (not just in XSI ) try curl noise instead, whilst a bit more setup I do believe that is what it was designed for and you will not get particles 'stuck' unless there is some other logic in your tree making them 'stick' in the air
