After migrating, there are a few settings you may want to enable, to ensure that all the assets work correctly in your project.
Bullet Collision Channel #
In order for our foliage physics system to work correctly with projectile and beam weapons,
you must ensure that your project contains a collision type called “BlockedBullet”.
Go to Edit > Project Settings > Collision, and add a new Object Channel.
Name it “BlockedBullet”, and ensure the default response is set to “Block”.
(Please ensure there is no space between Blocked and Bullet)
Click Accept.
Vehicle Support #
Our Alien Physics World contains a demo vehicle to show you how to make your own vehicles collide with foliage.
To ensure this asset works correctly, you’ll need to enable the ChaosVehiclesPlugin.
To do this, click Edit > Plugins.
Then use the search bar and type in “Chaos Vehicle“.
Tick ChaosVehiclesPlugin.
Fluid Simulation Support #
If you plan on making use of Fluid Simulation, please enable the Water Plugin.
Underwater Decal Support #
If you plan on using our water decal, which disables the specularity of everything that is underwater, please turn on “DBuffer Decals” in the project Settings
Grass Trails & Rising Water Support #
If you would like to use our grass trails, Virtual Texture Support must be enabled.
Unless you have modified your project’s settings, this should be enabled by default in Unreal 5.
Regardless, you can check that it is enabled by going to:
Project Settings > Engine > Rendering > Virtual Textures > Virtual Texture Support
Control Input Mapping #
IGNORE IF USING 5.3 & ABOVE!
By default, our Foliage System comes with some demonstration characters, such as the Advanced Locomotion System Pawn, the Mannequin Pawn, and a Vehicle.
If you would like to use these in your own project, you may have to transfer input mapping or create your own custom input for these blueprints.
If using 5.0, you will need to copy over the DefaultInput.ini file from the Config folder, and overwrite your own input config folder.
Otherwise, you will have to manually create the same inputs in your custom project to match the Alien Physics World project.
If you are using 5.3 or above, the our Foliage Physics assets will come with Enhanced Input and you won’t need to make any changes.
