ia scatter 是一个简单、快速且功能丰富的散布工具，适用于虚幻引擎。

它可以用于在任何表面上散布静态网格或蓝图角色的实例。适用于抽象、植物、自然、岩石、建筑物、建筑物上的天线，适用于任何东西。

ia scatter is an easy, fast and feature rich scattering tool for unreal engine.

It can be used to scatter instances of static meshes or blueprint actors on any surface. suitable for abstract, plants, nature, rocks, buildings, antennas on buildings, suitable for anything.

无论您是在创建一个大型开放世界环境还是一个小型室内场景，ia scatter 都将帮助您为项目注入生命，并在短时间内创建自然且身临其境的场景。这个工具帮助您通过几次点击散布资产，在几分钟内轻松、精准地创建无缝且令人信服的环境。通过避免繁琐的手动放置来节省时间并提高生产力，同时仍然保留随时进行更改的灵活性。

Whether you're creating a large open-world environment or a small indoor scene, ia scatter will help you bring life to your project and create natural and immersive scenes in no time. This tool helps you scatter assets with a few clicks, creating a seamless and convincing environment in minutes, easily, with precision and control. Save time and increase productivity by avoiding tedious manual placement, while still retaining the flexibility to make changes on the fly.

Features:

•Preset saving and loading system.

•Cable system.

•Area, spline, planar, linear and point tracing options. 1D and omnidirectional

•static mesh voxelization distribution and texture map instance projection

•static mesh, actor(blueprint), skeletal mesh, niagara system and geometry collection instancing (with probability setting)

•voxel geometry generation

•convex / concave detection mode

•clustering

•proximity to actor scale

•scale falloff gradient with ratio control

•look-at rotation options and target (3d widget)

•use spline from separate actor

•apply spline rotation to instances

•fixed instance distance along spline

•tracing special behavior based on physical materials and selection of actors

•ignore actors from trace (trace passthrough)

•Avoid overlapping (3 methods) and instance minimum distance

•Slope angle distribution

•function in control panel with autoPopulate (append selected static meshes or blueprints to selected ia scatter(s))

•function in control panel to convert scattered instances to actual scene actors and instanced foliage actors

•Scattering area can be rotated to face any direction

•Separate instanced mesh relative scale

•location grid snapping

•Static mesh proxies

•Complete instance rotation control with rotation snapping

•Complete instance uniform and non uniform scale control

•Align instances to normal

•Instances distance from face (along normal)

•Instance collision type selection

•both construction script and event graph / runtime execution

Notes:

•Since version 1.98 ia scatter needs the Geometry script plugin enabled. The plugin comes with unreal engine editor and to enable it you can follow the steps at the beginning of this video.

•ia scatter for unreal engine version 4.27 and 5.0 is currently provided without all the example maps. the remaining maps will be recreated and added in a future update.

•Voxelization does not work for 4.27 because of unreal engine 4 limitations.

•This is a blueprint product, the assets shown in the videos and screenshots are not included. Some polyhaven.com assets are included for testing purposes.

•Enabling Nanite for all static meshes is recommended.

•Enabling preserve area for the foliage static meshes is recommended.

支持引擎版本：UE4.27 and 5.0 – 5.5
