Because what use is this blog without a few tutorials, right?
Btw, if you have no idea how to use AutoLuminous, check the AL page for basic instructions. (Also, at the time of writing this, the latest version is AutoLuminous2, so don’t forget to download that if you’ve still got an old version.)

Here’s NajeMiku with AutoLuminous loaded. (and diffusion, softshadow and post_alphaeye) Now let’s fiddle with numbers. Remember not to pick any large numbers or it might burn your eyes and/or destroy your computer.
- Si: …you should already know that this increases the amount of emission/glowiness.
Have a pic, anyway. I set the value to 5 here.

- Tr: This changes the amount of blur on the effect. There’s not much of a range here, so it’s a bit subtle unless you directly edit the parameters in the .fx file. I’d… rather not get into that.
Here it is at 0.1.

- X: X changes the amount of glare, adding rays of light depending on the value. For example, here we have it set to 4.
r = (x)2
…wait, no, you don’t want math.
The amount of rays is double the value of x. Since the value of x is 4 here, everything with autoluminous has 8 rays of light shooting out of it.
- Y: Y adjusts the brightness of the screen. Simple.
Here it is at 6.

(I don’t think I need sample pics for anything after this.)
- Z: Z is the same thing as Si, but with different parameters. For example, having Si at 1 and Z at 100 would be the same as just having Si at 2. It adds extra precision to your autoluminous settings, in case just relying on Si is too strong for you.
- Rx: This rotates the rays of light that you set with X. Pretty self-explanatory.
- Ry: This changes the length of the rays. Also self-explanatory.
- Rz: Rz makes things blink. Positive numbers make it glow smoothly, negative numbers make it flash on and off. The larger the number, the slower it blinks.
And there you have it. I apologize if this post is too long ^^;
Have fun!
