I was wondering....how do you make realistc len flares on FXLab? You know were you place a the optic and the lens flare thingy moves. Do you understand? Like all the little round thingys move when you move the body of the flare. Yeah, how do you make those?

It might be easiest to open one of the lens flare presets, and take a look at how it works. For example, Open the blue flare preset that comes with the program. Cogz has a better mastery than me over how this works, but I think I can explain it for you.

Basically, each shape that you add has sliders to control its Distance nad Location. Blue Flare has 13 different shapes, all strung out in a line. So you create each individual shape, adjust its color and move it to it proper location. Generally, all of the shapes will be in a straight line, so you won't have to use the Offset sliders at all. You just leave all of the pieces in the middle of the screen, where they are originally created, and set each piece to a different Distance. then when you move the origin point of the effect, the math will all be done for you, and the relative movement of each piece will be done automatically. You might look for photos with real lens flares to try copy if you are not sure what colors to use or where to pace them. Otherwise, you can just make stuff up.

Once you have all the pieces in line, you can control how the whole effect moves using the Optic Movement controls, accesible from the timeline. Now just click on the control point on the canvas, and drag the effect to where you want it to be, and all of shapes involved will move to maintain the appropriate angle. I think that basically explains it, but getting them to look realistic is probably best done by copying a real lens flare to begin with. If I was unclear or you hav other questions, let me know.

The simplest way to run through this process is probably to create all of the elements of your effect in the center, then move the origin point to one of the top corners. Now you will be able to see all of the individual pieces and how they relate to each other, then you can go back and adjust them accordingly.

No, i think i understand but unless I missed something in there, when i make it look the best lens flare i can get (which isn't very good) i move it but all the little round thingys (sorry i don't know what to call 'em) just stay to the right corner or to the left... It doesn't seem to move. Like I said i probably missed something i'm going to read through what you said again. confused

Yeah, I think I understood.. (I hope)

You just change the "distance" slider to were you want them, and the flare-object will be on the opposite side as the actuall lensflare...

Hope that was what you ment..! smile

Hehe, the distance control. Good point. Use the distance slider to set the distance between the individual shapes. Then when you move the effect, the computer can calculate how they would move in relation to each other. I have edited my first post to make this clearer and simplify it a bit.

It's quite simple....plus i don't know if they'll put it in or not. But i was working on another one....and i'm not quite sure how to use the distance controls. the other thing is is that i think i know how to use it but i did something wrong...when you make an effect (like this) do you not worry about offset x and y? do you just do teh distance thingy cuz i did offset and distance and it didn't turn out well, so is that what i'm doing wrong confused: neutral

I'm not quite sure (I found out the distance-thingy the same way..!), but I don't think you have to mind the offset-sliders...
I don't know... Just play around, and I'm sure you'll come up with something great! biggrin

Reading this thread i can see people are a little confused about how the optics engine works. I'm pretty busy at this particular moment, but will try and post a tutorial about how to start one off very soon, explaining the attributes and what they do, and so forth.
