In this step I want to get rid of any large differences in luminosity within the texture to help it repeat better.

Any seams within the texture can be fixed by erasing the upper layer in which they can be seen. In addition to the lens and perspective correction, hue/saturation, match colour and brightness/contrast were used to make the photos fit better together. You also often get some vertical perspective as the area photographed is limited by the feet of the person taking it, causing the photographer to take the shot aiming slightly forward rather than straight down. As this isnвЂ™t always practical, most photos will be taken with the lens close to the ground with some lens distortion. The perfect base texture for a ground texture is taken far away straight onto the surface. Here the textures were put together in different layers in one big 1024x1024 map with some basic fixes such as lens correction to remove distortion and some vertical perspective depending on the base texture. Because you need an above average amount of source ground they must be taken from a higher position than a typical photographer would use. Generally you would want to avoid stitching several textures like this together, but it can be hard to find photographs that cover enough ground for tile textures. To the right are the four photographs that were used to create this texture. There is no need to have a library of your own except for a small number of special things you need or exceptionally cool texture photos that you manage to take yourself. CGTextures does all that for you and has a huge number of good texture photos.

I soon realised that it takes a lot of time to index and sort a collection that is large enough to be useful. When I started out, I had this idea that I needed a personal texture library. I currently get about 90% of all my textures from. The first obvious step is to get a good photo base. The remainder of this article describes how an artist can go about creating these textures. Here is an article about the details of implementing this on the programmer's side. Using the GPU its possible from an image like this to generate a very large non-periodic texture. By constructing a texture in this way we can get a set of textures that can be tiled for a long time without being able to see any large scale repeating patterns. Each blue vertical line will tile with any other blue vertical line and any orange vertical line will tile with any other orange vertical line. On the right you can see a set of 16 tiles. To break this up we want to have more than one different tile edge that can be connected together. The problem is that if all tiles have the same repeating edge then you would see a clear square pattern to the texture at the edges where each tile goes to the next one.

If we have a set of tiles then we can randomly place them in a grid and we shouldn't ever see any large-scale repetition.ДЇor this to look good we need to make sure that the seams between the tiles are continuous. You can imagine this just like assembling tiles in a 2d game. In order to make a non-repeating texture, one approach is to use tiles. This tutorial is designed to give some insight into the process we use when creating these textures.

One problem is that there is very little in the way of information for artists about how to create tile textures. In Path of Exile we use tile-based texture mapping extensively to break up the repeating patterns that would otherwise be very unsightly. There are many techniques that can be used to achieve this including detail textures, various methods of blending between textures, and tile-based texture mapping. One of the key difficulties in creating good looking ground materials is trying to stop visual repetition when seen from a reasonable distance. 1 Development Diary: Creating Tile-Based Texture Maps for GamesДevelopment Diary: Creating Tile-Based Texture Maps for Games.
