These textures originally came from CGtextures.com I just tiled them and generated the ssbump maps.

The below two links are to a concrete tile texture and it's ssbump map. I have not included a picture of these textures because they are 2048 X 2048 pixels. But I do have a picture of what they look like when I tested them. (Click the image for a larger picture) Click the link to download a zip file containing the .vtf and .vmt files. Just extract them to your material folder.

Below is a brick wall texture with its ssbump map. The links are to to uncompressed TGA files. They are 512 X 512 pixels.Brick_Modern_Large01.tgaBrick_Modern_Large01_ssbump.tga

Yours needs oversampling and maybe some surface smoothing by a pixel threshold.

I'll have to look into that. Do you know of anywhere that I can find more information on the methods of calculating those?

I have recently updated the program. More information can be found at my website.

The main update is that I added a GUI. Below is a picture.

Thanks.

The program has gone through several versions since it was first created. I'm always open to suggestions for more options. The people over at interlopers.net have been very helpful during the development of this program.

Self-Shadowed Bump Maps are slightly different than normal maps. They render slightly faster, and can cast shadows on themselves.

There has been another major update to the tool. (The height map smoothing has a really nice effect when set to around 3 or 4.)

Thanks to MrTwoVideoCards from interlopers.net for the contrast, smoothing, non-normal map generation, and minimum/maximum value ideas.

1. Fixed bugs.
2. Optimized more.
3. Now it has an option to run in multi-threaded mode for multi-processor computers
4. Added a contrast option. 1 for increasing the contrast of the height map and another for increasing the contrast of the final image.
5. Added a smoothing option. 1 for smoothing the height map and another for smoothing the final image.
6. Added an option for generating ssbumps without the normal map. Either use the command flag or input a 24 bit image.
7. Added an option to specify the minimum and maximum color values when calculating ambient occlusion.

The update can be found here, and more information on usage will be available at my website.

Enjoy.

A Self shadowed Normal Map generation program that I wrote. It converts height and normal maps into the new Self-shadowed normal map format.

I like to make custom textures, and a while ago I heard about the SSbump. I looked around for information on making ssbumps, but found very little. So, I wrote a program called SSbump Generator to batch generate them.

A download link and more information can be found here.

SSbump generator is a free program that can be run from the command line or with specially formatted txt configuration files. The purpose of this program is to generate Self-Shadowed Bump Maps for VALVe's Source game engine. The program can either generate non-shadowed ssbump maps or embed directional ambient occlusion into the image.

The image on the top was generated by my program. The image on the bottom is from a paper written by VALVe that discussed SSbump maps.This is a screen shot of one of the ssbumps that I made. (Click for a larger picture)

Go there and download the program... There is a free and a pay version. The free version will work.
