Preparing Long Hair Evolution
Make sure you have Kozaburo's Long Hair Evolution installed.
I found the textures in runtimetexturesKozaburo.
Bring the file long_evo_platina_tx.jpg into photoshop. We want this one because it will be easiest to remove the highlights from a lighter hair color than a dark one.
The background on this texture never shows up in the render, but it will unfortunately influence the following steps so we need to adjust it.
- Choose menu item Select/Color Range to bring up the dialog box that lets us select pixels of a given color range.
- In the Color Range dialog, set the Fuzziness to 20. (Other textures may need more fuzziness. For example, short bob needed around 40+)
- Click on the dark ground background in the picture to select that color. Don't click on the hair.
- Press OK to Dismiss the Color Range dialog
- Leaving the selection active, convert the image to gray scale by the menu item Image/Mode/Grayscale
- In the color picker palette, enter 25% - this should load a light gray into your tool.
- Hit Alt-Delete to fill the background with this light gray color.
- Clear your selection region by hitting Ctrl-D.
- Choose menu item Filter/Other/High Pass...
- In the High Pass dialog, enter a Radius of 15.
- Click OK on the High Pass dialog. The highlights are now gone.
- Choose menu item Image/Adjust/Levels...
- You should see a black peak in the middle of the Levels dialog. Press Auto to strengthen the contrast. If the lower bound is not tight with the group, move it up manually.
- Dismiss the Levels dialog by hitting OK.
- I prefer less grainy textures so I usually shrink the texture here. Select menu item Image/Image Size...
- Make sure "Constrain Proportions" is checked.
- Make sure "Resample Image: Bicubic" is checked.
- Enter a width of 1024. The height should adjust to 954 automatically.
- Dismiss the Image Size dialog by hitting OK.
- Use File/SaveAs to store this image in the same directory, but under the name long_evo_generic.jpg. Use Quality 10.
That's it!
You now have a texture from which we can make an infinite number of colors in the material room.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
