The Secrets of Realistic Texturing – The GIMP Way – Part 1
In this tutorial, I will take you through the process of realistic texturing your objects and models in Blender realistically. Many renderings you may find around might just have the necessary geometry detailing, good lighting, and rendering, however, the texturing makes the whole results unrealistic and not appealing to the eyes.
Nothing new here. Using the same Threshold color feature, increase the sliders of the left and right handles till you get something similar to the one below (you can read my values in the Threshold box)
Normal Map Texture
khophi@rex-Aspire-one:~$ sudo apt-get install gimp-plugin-registry
|installing your gimp-registry-plugin which comes with the Normal Map feature|
A whole bunch of options will available for your use including the ‘Fx-Foundry’ and ‘Script-Fu’ menus with many options.
However, we are not going close to any of these. Click on Filter >> Map >> NormalMap. Without installing the plugin registry for GIMP, you won’t see the Normal Map option. See image below to check out my settings for the normal map.
The trick for creating the displacement texture in GIMP isn’t perfect for use now, though it works to some extent nicely. Displacement texture should affect the z-displacement of the texture and should give a bit of depth to what’s being worked on.
|Settings pertaining to the Displacement Texture creation|
I went about creating my Displacement Texture the hard way this time round. Locate the BumpMap option (Filter >> Map >> Bump Map) and tweak the Azimuth and other options till it matches your taste.
The outlined ways of going about in creating the textures for use in texturing have got their own limitations are compared to the output results from software like CrazyBump which have well-defined settings for giving out the best result. Known limitations of the above strategy are:
- Normal Map lacks the option of inverting direction of bump
- Creating displacement is possible via Bump Mapping which compares less to result of CrazyBump
- Achieving your Specularity, Diffuse, and Occlusion textures are all possible by very manual try and error means, as compared to CrazyBumps’ well-defined settings.
- Settings for achieving the right spec in one material might be different from another.
To achieve realism in your renderings, giving a bit of attention to your textures is worth it. You can learn how to send these hard-earned textures into Blender and allow Blender apply its magic to them on blenderguru.com
