How To Use

Note: This tutorial is for the UE5.0+.

We advise you to open the Demonstration map provided and look over how the asset is used first.

Poison Toxic Goo Lake

Simply drag and drop the BP_PoisonToxicGooLake Blueprint into your scene.

To scale the liquid surface, use Liquid Mesh Grid Size X/Y and Liquid Mesh Scale parameters within the Details Panel, rather than the default scale on the overall Actor.

The Liquid Mesh Grid Size X/Y defines how many water meshes are used for the surface. This will basically define how "tessellated" the surface is for the deformation effects.

You can change the color of the surface from the Details Panel under Liquid Color.

Changing the color here will also translate to the post process "Waterline" effect.

Bubbles are enabled by default and the parameters are:

• Enable Bubbles: Toggle to enable/disable the bubble effects

• Spawn Amount: The amount of bubbles to spawn on the liquid surface. (Bubble spawn amount will increase automatically with the scale parameter.)

• Lifetime Min/Max: Controls each bubble particle lifetime minimum and maximum time in seconds.

• Size Min/Max: Controls each bubble particles scale minimum and maximum.

• Z Offset: Sets the Z axis location offset for the bubble particles. (Used in some cases where the particles need to be offset from the surface.)

Poison Toxic Goo Spray

Simply drag and drop the BP_PoisonToxicGooSpray Blueprint into your scene.

This Blueprint is located in the same location as the BP_PoisonToxicGooLake listed here.

The parameters for the Spray Blueprint can be changed directly in the Details Panel under the category Particles.

These parameters are:

• Color: Controls the color of the spray particle and the splash particle.

• Render Sort Order: Used to set the translucency sort order of the splash particle (helpful in some use cases where you need to specify how the particles look.)

• Velocity: Controls the velocity of the spray particle.

• Lifetime: Controls the lifetime of the spray particle.

The splash particle is spawned using collision within the Niagara System.

Poison Toxic Goo Post Process

Drag and drop the BP_PoisonToxicGoo_PostProcess Blueprint into your scene.

This Blueprint is located in the same location as the BP_PoisonToxicGooLake listed here.

This Blueprint is a simple drag and drop and has no parameters to modify as it's used to just enable the on screen "waterline" effect for the liquid surfaces.

Only one BP_PoisonToxicGoo_PostProcess is needed per scene.
