PerPixelMultiMap with Emissive map (shader) for Assetto Corsa

What this mod does

PerPixelMultiMap with Emissive map is a shader by Stereo that adds a fifth texture slot, txEmissive, to Assetto Corsa’s ksPerPixelMultiMap shader. That map scales the existing emissive value, so you can control which areas of a texture glow and how brightly. It has over 48,000 downloads on OverTake with a perfect rating, though from only seven reviews.

What it’s for

Painting the map white gives you the original emission, while darker or colored areas change the brightness and tint. The author suggests uses like position lights, lit building windows with different brightness levels, or backlit signs that don’t light up evenly. A later update lets the map’s alpha channel control transparency.

Do I need it?

• If you’re a player: some cars and tracks require it if you play without Custom Shaders Patch; without it, the game may crash when loading them. Install it when a mod says so.
• If you’re a modder: select ksPerPixelMultiMap_emissive in ksEditor to use the new map.

Installation

Just extract the system and sdk folders into your Assetto Corsa folder. According to the author, it doesn’t overwrite any original files. If you redistribute your mod with this shader, the author asks you to include the system folder.

Requirements

• Assetto Corsa for PC
• ksEditor from the Assetto Corsa SDK if you'll use it to make mods
• Free OverTake.gg account to download

How to install it

1. Go to the shader's page on OverTake.gg, log in and download the file (about 4 KB).
