Is it somehow possible to have more than just 4 dynamic scalar values in cascade to control material?
I would assume you would use multiple Dynamic Parameter nodes, they are just vector4âs.
You cant sadly.
But with some experience you could use a âparticle color nodeâ as a dynamic parameter as well, though with some limitations.
Additionally there are nodes like âParticle relative timeâ wich outputs a 0-1 over the lifetime of the particle/
âParticle Randomâ (gpu only) which outputs 32 random values between 0-1 for each particle emitted.
And if you know how to use If nodes, you could make it so if the Red output of a dynamic parameter goes above 1, it activates something else than when its below 1, and again for when its above 2, above 3, etc.
Hi , thans for your response,
I had the same idea, to use âifâ nodes and kindoff make a switch, where positive and negative values would be used as two separate values, and although itâs a great trick, we still canât have more than 4 values at the same time, because one value canât be positive and negative at the same time.
But âparticle colorâ and âparticle relative timeâ could be very usefull actually. I could setup the color of the particles in the material (and never change it), and use 1 - âparticle relative timeâ to drive alpha of the particles (since I want simple fade out). That would give me 4 new parameters from the particle color node! 
Which is exactly what I needâŚ
I hope Niagara will fix this kind of issues in the futureâŚ
Thanks again , great to have you around
what you can do once you set up a color for the particle, is use hueshift node and use only one of the RGBAâs from the particle color to modify the hueshift.
I know this is old but I stumbled upon this when trying to work out the same thing.
I figured out that you can indeed have multiple Dynamic Parameters and all you have to do is increase the âParameter Indexâ, Each Index has itâs own set of Outputs.

This is because that function has been added quite recently.
Back in 2017 this was not possible
Its good that you posted though, in case people nowadays are wondering if its possible!

Yes, but there are only index 0 to 3, and I can´t find anything to add a new index within the particle system.
So are we really limited to index 0 to 3 or have I just not seen how to add higher index?
Feedback much appreciated.
no, four tops (0-3) and unless you are doing something really crazy, 4 is generally way more than enough. If you need one more, you could still use a particle color node as a fifth, as its basically the same thing as a dyn. parameter, just without parameter names.
If youâd need even more, you might want to consider other approaches to pass through data. Which, --besides simple stuff like uv maps/vert colors-- is not really my forte.
