I have a great idea for a CS set. I love it when people take pics of their roller coasters with 'splash zones.' However, this take hours and hours to get exactly right. So, I think that DazMatze and -Nuclear Fish- should get together and create Particle Effects Ride Events.
DazMatze has made a set that turns every animatronic scenery object a ride event, and -Nuclear Fish-'s particle effects CS set is the most popular effects CS. So, if they mixed the ride events and particle effects, the 'splash zones' would no longer take hours to make.
Also, at the same time, DazMatze could try and make the Generic Scenery objects Particles (Fire, Smoke) ride events, and even hack the MixMaster and allow the bases to be triggered as ride events and shoot off fireworks, lasers, and water jets on queue.
Finally, while working on this set, they could make new particle effects for us.
This would be a great CS set that would certainly have my download!
