Normal Maps, Bump Maps, and Displacements Maps
Over the "digital ages," the battle for more efficient texturing algorithms has never stopped. Graphics hardware and software leap-frog each other in both the gaming and technical industries in an effort to make textures look more realistic. Many new technologies fall by the wayside before most of us ever hear of them, but some of them endure for years. I'm going to discuss 3 of those enduring texture mapping methods today. They are...
- Bump Maps
- Normal Maps
- Displacement Maps
Get Some Free Publicity!
Do you want to get some free publicity for your talent, company, or portfolio? I am looking for Genetica users who would be willing to share their experience with me. I would like to start a Featured Artists series on the site to feature fellow Genetica users, show some of their work, describe what they do, and link to their site if they have one.
Here's what I would need from you:
- I need your answers to a short list of questions that I will email you regarding your experience with Genetica.
- I'll need your permission to use these answers to summarize or quote you on your feature page, and in my sales pages.
- I need your permission to use a few completed or intermediate images of yours that demonstrate the capability of Genetica. They will be credited to you - they are your works and you earned that right!
- OPTIONAL - if you link to www.TexturesWithGenetica.com on your site, I would appreciate it very much. You can link directly to your feature article if you like.
I will make the call on who I feature based on image quality. variety of artists, and how many requests I receive. If you are interested, please fill out the Contact form!
Send me your Genetica questions!
Maybe you have always wanted to know how to do something in Genetica, or maybe there's a particular Node type that has always given you trouble. If so, use the Contact link and ask your questions. You might just discover a tutorial post with the answers!
Tutorial on Combination Nodes (and Blend Modes)
One of the most powerful tools in many high-powered image editors is the ability to combine layers in multiple ways using Blend Modes. Instead of just saying, “I want Layer A to interact with Layer B a little bit,” Blend Modes allow you to say exactly what kind of interaction they should have.
In creating textures, a common example of blend modes would be when you have a textured wall and a grunge texture that you want to put onto that wall. Blend modes determine how they combine. But what if you want to put the grunge only at the bottom of the wall? That’s where Genetica’s Combine Node comes into play with it’s third input, the Selector Node. I’ll leave it at that since there’s more on the video.
NOTE: Don’t confuse “Blend Modes” and “Genetica Nodes” here. In Genetica, there are numerous Blend Modes available. Two of the most common modes are A+B (Add) and A*B (Multiply), and they are so commonly used that they got their own Nodes named after them… isn’t that special?
Go watch the video and learn about Blend Modes in Genetica! Leave any questions/comments that you want. The video is about 12 minutes long.
P.S. - You can right-click here to download the Genetica file used in the tutorial. Make sure to click the EDIT button on the node group at the bottom to actually see the part used in the video.
P.P.S – I used Pro for this tutorial, but you can use any edition of Genetica.
More Genetica tutorials from the new Spiral Graphics Blog
Spiral Graphics just started a new Blog on their site. It has the intent of having more How-to texture-creation tutorials. They already have the following posts:
- What is a Seamless Texture (3D Texture, Tileable Texture)
- Create Custom Brick and Tile Patterns
- How to Import Models and Textures into Unity

Genetica 3.51 Released!
The newest release of Genetica is a big win for anyone who uses it to create realistic 3D textures. Current Genetica users know how powerful it is already and it gives them an edge over their competition. So many textures can be made without the need for Photoshop and the Clone Tool, saving them time. Genetica 3.51 is free to Genetica 3.x users.
