Need help making rifle scope lense.

Are you talking about making just a glass lens? :)

If so, that should be really simple - in fact, whatever software you are using probably has a glass preset that you can use to start off, and then just tweak to perfection ;)

The important thing for a lens is to model is correctly. Once you have the model correct, then applying and tweaking a glass surface setting to it shouldn't be too difficult.

All you need for a basic glass surface is a high degree of transparency (not a low level of opacity), a bit of reflection, and some refraction (around 1.2 for this type of glass I think). Then just set your diffuse to 0 (or your colour to black), and you should have a decent glass to start off with.

I mean just skin a lense like create it in photshop, not in 3dmax or w/e. Thx

Aaah right... errmmm.... well... in that case, why not try making a spherical shape with some vague gray details to mimic reflectivity, and then perhaps overlay it with a radial gradient to mimic the shape of the lens, and then change the blending mode of the layer to something like Dodge or Overlay, to get a glassy transfer look?

ok cool but, where do I get this radial gradient and stuff. Im sorta new to photoshop. thx

For a scope lense here's what I would do:

1. Open Photoshop and create a new document
2. Press 'D' on the keyboard (Resets color swatches)
3. Press Ctrl+Alt+N (New layer)
4. Choose the circular marquee (Press 'M' then if it's not it, rightclick on the square marquee and pick the circle one)
5. Hold Shift + Alt, and create your circle from the middle of the document. This way it will be a perfect circle.
6. Press 'G' to select the gradient tool.
7. At the top of the screen where it shows the gradient options, select Radial Gradient (As leigh suggested)
8. Check the 'Reverse' button at the top of the screen.
9. (Your selected area should still be selected) Select your new layer (Layer 1)
10. Go to the middle of the selected area on the document, and drag outwards untill you get to the edge of the selected area.
11. Change the 'Layer 1' opacity to fit your needs (You may want to lower it a little.)
12. Create a new layer ontop of all the other layers.
13. After you create the new layer, (You should still have your area selected) Press Alt + Backspace (This will fill the area you have selected)
14. Change the opacity of the layer you just filled to '0'.
15. Create a new layer ontop of that.
16. Press 'M' to reselect the marquee tool again.
17. Hold Shift, and press the up arrow button once (This will move the selection up 10 pixels).
18. Go over to the layer panel, and hold Ctrl + Alt while you click on the layer that you just filled with all black (Probably named 'layer 2').

Note: Now you should have only about an eighth moon selected.

19. Hold Shift and press the down arrow.
20. Press D then X, so you have white selected in the color palette.
21. Press Alt + Backspace to fill that area with white.
22. Ctrl+ Click on the layer that has the filled in black circle.
23. Go back to the later you just filled with white, and Guassen Blur it. (There is no specific ammount).
24. Where the layers palette is, click on 'Channels' to the right of it.
25. Create a new channel, by clicking on the button third button from the left at the bottom.
26. Create a lens flare, small, but inside the area of the selection. (Use 105mm Prime) (You may have to create a new layer in the layers panel and fill it with complete black, then create the lens flare, then copy that layer into a channel, and ctrl+click on the channel, to select where the lenseflare was. Then go back to layers and make a new layer and fill with white the selection you have. It should be a lens flare without any background.)
27. You can do another of those if you want. This is really the first of a lense I've done, but I've done orbs and such, which is pretty much the same.


I hope you can understand all this.;)

thx for help but I lost you on number 26 part of tutorial. Lens flare is blocked out so I cant use it when im doing the channel thing.

[Jensen]

K, here's what you do for that part then:

Create a new layer.
Fill it with black.
Create the lense flare.
Press Ctrl + A
Press Ctrl + C
Go to channels
Create a new channel
Press Ctrl + V
Control Click on the channel you made (It'll select only the white parts)
Go to layers
Create a new layer
Select white as your color
Press Alt + Backspace to fill it in.

Unless you want something like this.
