Post subject: | Texture Creation Tips |
Someone PM'ed me asking about getting started with creating textures in Photoshop. Since this is a general advice topic that everyone can benefit from, I thought I would post this publicly (you can still PM me if you have any private questions). POST EDIT: I may edit this post later with more stuff and maybe a few images. I'm too hungry right now to keep typing. Get a Drawing Tablet Pressure sensitivity when painting is key. It gives you a completely different dimension to work with than a mouse. A mouse button is digital, click or not clicked, 100% or 0%. A pen and tablet is analog, giving you 1024 (or more) levels of pressure sensitivity so you get full control of brush size and opacity. Wacom is the de facto drawing tablet manufacturer. There are a few knock-off brands but most should be avoided. Wacom makes 3 main product lines, the consumer Bamboo, professional Intuos and the high-end Cintiq (display + tablet in one). Each comes in a variety of sizes. The Bamboo has 1024 levels of pressure sensitivity and should work fine for most beginner texture artists. Intuos has double the pressure sensitivity (though on an 8-bit/channel image, you only have 128 values for shade so you're not likely to ever notice) and will also detect the pen's tilt. This is more useful if you do a lot more freehand painting. Textures are fine with a Bamboo, get an Intuos if you're doing other illustration work. You probably won't be getting a Cintiq unless you have a few thousand dollars sitting in your cookie jar. Get the size that you are comfortable working with and that you can afford. They don't take a lot of wear damage and are well built so you can feel good about investing in one. Note: I've been having trouble with the latest drivers (6.1.6-7 for Windows 7) with regards to pressure sensitivity. If you find that you are having problems with intermittent fat lines when drawing, try rolling back the drivers one or two versions. Calibrate Your Monitor Anyone who uses a computer a lot should probably do this anyway. Make sure your monitor's output is what it should be or you'll be painting with the wrong shade for all your textures and end up with a hot pink texture theme rather than red. Monitors out of the box are typically calibrated for showrooms but are actually horrible to really work on. There is software to help with eyeballing your calibration (Windows 7 comes with "Calibrate Display Color" utility) but I would really recommend a hardware calibration tool, they aren't expensive anymore so you should pick one up and are infinitely more accurate than eyeballing, which will also make you go cross-eyed. Calibration tools stick on your monitor and the software runs a bunch of colours on your screen while it samples the colours. An .icc profile is generated by the software which your OS uses to correct your display. Setting Up Photoshop There isn't too much to set up for Photoshop, but I do have a few pointers. Check your preferences (Edit > Preferences)... File Handling > Maximize PSD and PSB File Compaitiblity > set to "always". Performance > Set your scratch disks if you have multiple drives. This is cache data that Photoshop uses, you can get a performance benefit if you put the scratch on your faster drives/partitions. If applicable on CS4/CS5, enabling GPU support helps speed and enables cool stuff like 3D model painting. Cursors > Normal Brush Tip and for Other Cursors, choose Precise. Guides, Grid & Slices > Set gridline to 32 with subdivisions 4, you may need to alter as necessary. This helps when you are working on the grid with textures. Make sure you are working with 8bits/channel and RGB Color in Image > Mode. Basic Photoshop Techniques
Basic Keyboard Shortcuts
References Yeah, the web is full of tutorials, pick and choose a million. I'm sure there are a few good Photoshop books, but I never bothered to read one - Photoshop's interface may seem a little overwhelming at first, but it's actually quite intuitive and you'll learn where everything is soon enough with just random clicking and trying stuff out. I've self-taught myself Photoshop starting with version 2.5 and there really wasn't much help on the Internet in the '90's. Adobe TV, while they are really trying to sell you on the product, does have some fantastic video tutorials teaching you about various techniques and tools, great for beginners and people who want to brush up on their skills. I've been watching ctrl+Paint recently for practising my freehand illustration techniques. If I had to choose just ONE texture creation tutorial on the Internet, I would pick Hard Surface Texture Painting. Keep Practicing and Learning Photoshop is one of those programs that you get better at with frequent practice. Occasionally, you'll learn about something new or develop a new technique which may completely simplify, improve or change your workflow. I still learn new stuff and figure out cool ways of doing things. |

In addition: Play around with custom brushes! Figure out what all of the brush settings do, especially jittering opacity, hue, saturation, etc. Being able to set a texture on a brush is also invaluable. Be sure to get a custom grunge brush pack for dirty textures. |

Over at cgtextures in the tutorial section there is a article discussing different blend modes, and using blend if, and blend ranges. |

What is "Bevel & Emboss Syndrome"? Photoshop has a Bevel & Emboss filter and it's great for certain effects. However, beginner texture artists think it's super nifty, and start overusing it for adding highlights and shadows to surface edges. The filter has a very distinctive look and overuse makes your textures look obviously passed through a Photoshop filter. The problem with using the Bevel & Emboss filter is that it looks exactly like you used Bevel & Emboss. If you find yourself doing this, and your textures have those distinctive highlights and shadows, you have Bevel & Emboss Syndrome. Web designers hate it too, I found this image as #2 under a top 10 do-not-do-for-web-design list. What's the Cure? Hard work, that's what. The reason why beginners use B&E in the first place is that it's easy and they get to avoid hand painting highlights and shadows. The long and hard way is still the best way. No cutting corners! If you haven't done so already, get yourself a Wacom drawing tablet. Alternative 1: Dodge and Burn Try this, duplicate your working layer, then use the dodge and burn tools. Use dodge to add highlights, burn to add shadows. Alternative 2: Using Blend Modes This is my usual method. I created this as part of another tutorial on another forum, so I'm sharing it here: |

I use an alternative method. I create a base material using photo source images and then shape the texture to an editor grid. Once the texture works in the editor I stamp the details from various source images on top and then touch up the details by hand using a mouse. I also use a lot of different effects in PS to simulate depth of edge so I don't have to manually blend everything. I released the Photoshop source CS5.x file if anyone is interested.
