LCA | Lights, Camera, Action | A Reshade Shader (Patreon)

Introducing LCA | Lights, Camera, Action ✨🎬

Custom screen-space dynamic lighting custom FX shader for The Sims 4, for that cozy, flattering, cinematic look. Inspired by Marty McFly's iMMERSE!

What is it?

LCA is a ReShade shader (LCA.fx) that lets you place up to 4 dynamic lights anywhere in your scene. Point lights, spot lights, in any color, at any intensity.

Features

🕯️ Up to 4 simultaneous lights — each with full toggles so you can flip them on and off independently

🔦 Point AND spot lights — point for ambient room glow, spots for window shafts and dramatic angles

🎨 Full color control — RGB picker per light

✨ Soft, flattering falloff — smooth radius rolloff with no harsh cutoffs.

💡 Light wrap diffuse — gives surfaces a soft, skin-like quality.

🎯 Smoothed normal reconstruction — multi-tap sampling kills the polygonal faceting common to other ReShade lighting shaders

🌑 Optional screen-space shadows — for realistic, live, contact-shadowed light

⚙️ Tuned specifically for The Sims 4 — depth handling baked in, sensible defaults, just works

Sliders you'll actually use

Position (X, Y, Depth) — drag your light anywhere in 3D space

Intensity / Radius — how bright, how far it reaches

Light Wrap — the cozy/dreamy dial. Higher = softer

Normal Smoothness — kills faceting on Sims and curved objects

Falloff Softness — controls how lights fade at their edges

Spot direction & cone — for spot lights, point them like a flashlight
