Hi
im learning unreal and im trying to create visualizations for my “interactive floor system” (projections on the floor), i already spawn one actor per each foot of the people on the interactive area so now i want to create effects and animations that react to those spawned actors.
this a reference image of the system :
The effects i want to create are “water ripples”, “grass that leaves a trace”, “destructable city from above” and in general create some kind of visual reaction to steps.
I had no luck trying to find a way on how to create realistic water wich reacts to actors or how to leave a path on grass after someone just passed by.
So can you suggest what method to use to leave marks on materials (is it decals) ? or what would be my best method to generate massive effects for my projection?
Are these “dancing” 3D models, or is it a chromakeyvideo?
I am sure no pro here, but i would try(if 3D mesh) to add a linetrace at every feet to the ground.
Get impact location.
When you have the location you can spawn actors there or change mat.
Use timelines…
Ah sry:
When you still have the actors at place, you can spawn there exactly in the same way particles.
Or create BP actors of your spawnactors and insert the particles there.
Destroying city sounds cool. ^^
Perfect example, for your task, ask him, perhaps he is nice.
i found a basic ripple on the “FeaturesTour2014” on the boundcing ball blueprint,
so i copied the ripple (wich is a particle emitter with a translucent material) and changed a bit
the material to be more transparent
then using an interval i spawn the riple at my actors locations
i dont know if it is a good practice to spawn multiples emitters or if there is a way to make only one emitter
and control the particles locations
