The tuts you make are so very helpful and have been needed for a long time. Thanks."
Of course mate. Glad my tutorials can help.
This is obviously the diffuse texture. (from my SciFi Light)
All you need to do is draw a rectangle around the area that you want to 'mask' off. In this case, I chose the rectangle select tool.
When you have selected the area that you want to have illuminated, invert the selection (Ctrl+I)
Then delete everything else and using the bucket fill tool, simply fill in the void with black (or you can use your brush tool and paint the area in black)
When you have 'blacked out' the rest of the texture, you should be left with the coloured area, that you want to illuminate. Invert the selection again (thus selecting the non black area)
Then with the coloured section being selected, desaturate it.
You will then need to change the brightness values of the area you have you desaturated. Do this by changing the Brightness/Contrast settings.
When you are happy with the brightness of the illuminated area, you will need to export it all with the correct suffix (YourTextureName_
I.dds)
This is the finished Illumination map.
Sorry for the image heavy post! Its a bit late for me to be recording videos now! Hope this helps mate.
Cheers
Jay.
