The character is here for presentation only.
Parameters:
Ice - Color 1, Ice - Color 2, - responsible for the color of the geometry
Ice - Color 1 - dark areas of the geometry
Ice - Color 1 - light areas of the geometry
Ice - Color Power - color saturation
Ice - Color 3 - for snowflakes, light smoke after the ice appears, smoke around the ice, and the wave on the floor that occurs after the snowflakes twist.
Portal - Color 1 - color inside the portal, closer to the middle.
Portal - Color 2 - color inside the portal, closer to the edges and the middle itself.
Portal - Time - There is also a timer after which the portal will disappear.
The process looks like this:
1. You drag the portal "BP_IcePortal" to the level.
2. Use the "Select Color" checker, adjust the color, size and turn off the checker.
3. Launch the play mode and enter the circle of particles with any character.
4. The portal appears and lives as long as you set the time.
Notes:
There are 4 portals for testing on the "IcePortal" level. The character appears on a small elevation, this is done so that the character is at the same level with the portal and particles fly beautifully around it. If you lower the character to the ground, this effect of particle twisting will not be so spectacular.
If you would like to change the position of the particles around the portal activation site or the activation site itself, you will need to go to blueprint
../Content/_VFX/Ice_Portal/Blueprint/BP_IcePortal and change the position of the markers and the "Activate" activation capsule.
If you move only the "Activate" capsule, then the particles around this capsule and the initial particles that are the first to rush to the portal "NS_Vortex_Overlap" will also change.
The general particle with a large twist "NS_Vortex" of snowflakes is located just above "Marker_NS_Vortex" and it is aimed right at the middle of the portal.
In general, if you want to change the position of any particle, you only need to move the markers.
"Niagara for Color" section are only needed to adjust the color.
preview
update - 2.0
- Improved the ice material so it looks better at the level where there is a lot of direct lighting.
- Added a looped portal (Packed level)
- Added a track with ice
- Added a track with decals.
- Added looped smoke particles.
Now it is possible to put a looped portal on the level using the level packing system in unreal, which gives excellent optimization instead of using a looped Niagara.
In the "Packed" folder you can find 4 packed levels. Having put them on your level, just tweak the same color settings as on the first blueprint. Also in this folder there is a level with decals "PathDecals", which you can also put on the level, but without changing the color.
In the Niagara folder there are now two new Niagaras with looped smoke.
