Unreal Engine Blueprint - Spline-based Instancing
Blueprint that allows you to instanciate a number of static mesh(es) along a spline with a decent amount of controls and randomization. It's available as a Tier 1 reward on my Patreon: https://www.patreon.com/GhislainGir
Demo/Breakdown of the Blueprint
You may create a list of static mesh that will be randomly selected. They will be instanciated along the spline.
You may control the distance at which each instance is spawned along the spline.
You can randomize the step distance.
The blueprint may do a linetrace for each instance to attempt to find a ground given a trace direction & channel and max distance and project instances onto that ground.
Instances may be aligned regarding the slope of the ground.
Instances' scale may be randomized and offset in a couple of different ways.
Rotation may also be randomized and offset.
The blueprint may give each instance a chance to have a specific rotation on a given axis applied for extra randomization.
Location can be randomized and offset in all sort of ways, both in spline or world space (or both), before or after ground projection.
Blueprint allows you to set collision for those instances and offers the ability to use Hierarchical Instance Static Mesh Components instead of the regular ISMC and you may also change the randomization seed.
