Merry Christmas 2012!

Merry Christmas everyone! I'm planning on making a short video of the Mercpedia app, so I'll update with a video if/when I get that done today.

Leopard Class Dropship

I decided to make the app's "Home" button a leopard class dropship. Then I got a little carried away. Okay, maybe more than a little. This is based on Alex Iglesias' re-design, though obviously changed up a bit.

I think I'll continue working on it and see how much detail I can put in. It's definitely a candidate for 3d printing.

More Icons

I think I'm getting carpal tunnel from all this art. My wrist hurts like hell. Anyway, enough whining, here is another shotgun blast full of art for the Mercpedia app:

Boom Guns

How about something a little more familiar? Boom guns! Autocannons are a bit hit and miss in Battletech, and they're still undergoing a lot of balancing in Mechwarrior Online. Still, they're fun to draw :)

Livestream Online!

About to enter a livestream (5 minutes). You're welcome to come by and watch here.

I'll be working on stuff for the Mercpedia android app for the most part, but I might deviate a little bit. I also plan on doing this for quite a few hours (probably all day) with a couple of breaks in between.

Come check it out! :)

UI Update

We're getting much closer to being done. The UI has a lot more polish and some of the icons have been added (finally):

This is actually moving along rather nicely. Certainly much faster than I thought it would. It's cool what you can learn in a year :)

Gauss Rifle

Doing some more work on the app. I present to thee, the Gauss Rifle. Traditionally it has a round barrel and is more of a coil gun in Battletech. However, the rail gun is capable of higher velocities and is much more suited for defeating heavy armor. This one features a rear loading breach (instead of the usual side loading) and dual liquid cooling modules. Five, massive solid state capacitors store the energy necessary for expelling SABOT rounds at super sonic velocities.

Enjoy :)

3D to 2D art tutorial

This is a quick tutorial on how to make 2d art assets, such as icons, from 3d objects. For this tutorial, I will be using Sketchup and GIMP. Both of these programs are free and available on multiple operating systems, so anyone is able to get started.

1) Build the 3d model (this is beyond the scope of this tutorial because it is a very extensive subject. I do have information about it in older posts, and will most certainly continue to do so in future posts as well. Your finished model might look something like this:

2) Make certain that  View > Shadows is checked and fill the background with a bright color that will not be in your model. I use green (just like a green screen for movies). You can do this by going to Window > Styles and then making a new style. Go to the Background tab and check the Sky and Ground box, then set the colors for them.

And it show now look like this:

3) You need to export it to an image file so that GIMP can understand it. Sketchup also runs a very very basic rendering operation. It's basically applying anti-aliasing and smoothing to the image.

File > Export > 2d Graphic

Make certain to save it as a .png file.

4) Now, load it into GIMP and select the Select By Color tool from the toolbox. Select the green (you may have to select multiple sections to get all of it by holding the shift key) and delete the color completely. This will result in some left over residue:

Simply repeat step 4 on all the green pixels until they are gone.

5) Now use the fuzzy select tool to select all of the dead space, similar to how you selected the green in step 4.

When you have all the dead space selected, go to Select > Invert Selection. This will select your entire object without singling out dead space, color, etc.

6) Icons should always be a factor of 2 and square. That means you can always divide the pixel dimensions by 2 and the height and width are the same value. This means we need a canvas that fits these requirements.

Select Image > Canvas Size... from the top menu and change the dimensions to the nearest even number (you'll want to use the higher number if you have a rectangle). Note: Make certain the chain on the right side is broken! Otherwise, you will be forced to scale in the same ratio.

Make certain you press the Center button! Then press Resize.

7) Now we have the proper dimensions. In the layers window, right click and select Add New Layer twice. Name the first one Shading and the second one Lines. You should now have layers that look like this:

8) Select the bottom layer (it should have your image name or Background) and select all the dead space. Invert the selection just like step 5 (Select > Invert Selection). You should now have only the image selected.

Select the Shading layer by clicking on it and then click the Bucket Fill tool and select your desired color. I'm going to use one similar to the MWO theme.

Set the Opacity to 50% and then click in the selected area in the main screen:

9) Now, this is good, but you'll notice the details are muffled, specifically the lines. So now we click on the Color Select tool again and make certain the bottom most layer is selected. Click on a black line anywhere in the image to select all black lines in the image.

10) Modify the Bucket Fill options so that Opacity is 100% and the color is Black.

Then select the Lines layer by clicking on it. Now that it is in focus, hold the Shift Key and click inside your selection. Your image should now have much crisper detail:

11) Last step! Simply select Image > Scale Image and set it to the desired icon size. I'm currently using 100 x 100 px:

And now you have an icon that's ready to use!

Some tips for consideration:

  • Keep your final icon size in mind when designing your 3d model. It's possible to spend days making a professional model, but you'll lose 95% of that detail when you shrink it to an icon!
  • Create your theme and color scheme before making finished icons. Otherwise, you'll end up fixing them all again, and again... and maybe even again.
  • Save the .xcf file! Always, no exceptions! You can't edit layers once the image has been exported and flattened.


Here are a few more icons I've made:

Doing some strictly 2d art. I have to say I surprised myself. I never thought I'd be able to make animated sprites (even those these are pretty basic). They are concepts for an Android game, but we've since decided on a top-down perspective instead.

Crap, my blog is a bit too dark to see the treads. You can get a better look on my deviant art page.
