The Simple Light Painter (in short: SLP) is a material based Lighting System for your realtime Unreal Engine Projects and Games. It can light up the backside of your objects for indirect lighting and also offers simple localized Global Illumination with Emissive Material Support.

Try out the Demo Builds with runtime Examples and Performance Tests! (VR Pawn is not included with this Asset Pack)

❕ INFORMATION: This Lighting System is supposed to be used in addition to traditional Lighting Methods and is not a replacement. The Lights can not cast Shadows.

Available Versions:

4.27+ -> SLP v2.0

4.23 – 4.25 -> SLP v1.1

Simple Light Painter（简称：SLP）是一款基于材质的光照系统，适用于您的实时虚幻引擎项目和游戏。 它可以照亮对象的背面以进行间接照明，并提供简单的局部全局照明和发射材料支持。

尝试使用运行时示例和性能测试的演示构建！ （此资源包不包含VR Pawn）

❕ 资料: 这种照明系统应该是除了传统的照明方法之外使用的，并不是替代品。 灯光不能投下阴影。

可用版本:

4.27+->SLP v2.0

4.23-4.25->SLP v1.1
