Lightmaps are very important part of game environment production in UDK. The quality of baked lighting and shadows in your map depend on it. Lightmaps determine how your models are lit, how they receive and cast shadows.

Jul 3, 2012 · In this reprinted #altdevblogaday in-depth piece, game programer Simon Yeung shares an overview on how to bake light maps of indirect lighting data by sampling from the photon map.

Jul 15, 2024 · The light maps allow us to build up dynamic lighting systems for the game scenes which can contain multiple light sources. It is one of the most suiting lighting technologies for 2D...

This document explains / demonstrates the process of creating light maps for use in games or any graphics application. Objectives The goal of this document is to explain the process of creating light maps. It describes how light map lumels are calculated and how the final pixel color is …

Jan 28, 2013 · This is Lesson 6, a continuation of my GLSL Tutorial Series. In the tutorial, we'll take a regular texture like this and use normal maps to illuminate it in real-time. This technique can be applied to 2D games in a number of ways: see here, here and here. I …

Nov 7, 2012 · Let’s take a look at how it works in a simple example. I set up a little test area with a single point light to demonstrate the technique. For this example there are some terrain tiles I created in my engine as well as the player’s vehicle. I used GIMP to add a white dot where the light will eventually be located.

Lightmapping is still the preferred method of lighting in most games, namely because it is fast regardless of how many lights are in the scene, if you've ever shot at a light bulb that didn't break or it broke but the light around it remained then you have seen lightmaps in action (or lack of).

Jan 22, 2011 · To create an atlas (without scaling the lightmaps), create an image that is, say 2x larger than your lightmap on each edge. Then you've got a 2x2 grid of lightmaps. Dump the lightmaps into it, and adjust the texture coordinates based upon which lightmap they came from.

Apr 22, 2021 · PolyCrunch Games, developers of Pyramid Plunge, talk us through the process of lighting 2D games using normal maps in GameMaker with amazing results.

This is a tutorial on how to generate and render with static lightmaps, as seen in most modern Quake-ish game engines. We'll start with the very basics. I've made some small changes and clarifications since this document was originally posted, based on reader feedback.
