What is Okhlos?


Okhlos is a roguelike action game in which you control an angry mob of ancient Greeks who have set out to overthrow the Olympian Gods and destroy everything and everyone that stands in their way! It blends 16-bit styled pixel art characters with fully interactive 3D environments and features procedurally generated cities to rampage through. There are hundreds of unique characters that can join your mob!

Okhlos Features

  • Roguelike-like-like vibe! Each playthrough will be unique! Different heroes, different monsters, different bosses!
  • Procedural worlds! Okhlos has 8 worlds, each one procedureally generated and based on a different scenario from mythological Greece! You will never play the same level twice!
  • Make your mob unique! Each unit you grab makes your mob different! Choose from different types of units and heroes with special modifiers to make The Ultimate ANGRY MOB!
  • Fight the Olympus! You will have to face the 12 Olympian Gods to overthrow them! And they won’t come alone, you will also find a plethora of mythological creatures, ready to dissolve your mob.
  • Fast paced combat! Do you have what it takes to lead an angry mob? You will need reflexes and skill to dodge a centaur, beat up a cyclop or strike down a god.
  • Achievements, Steam Cards and Encyclopedia! Can you collect every monster, every unit, every hero in the game’s encyclopedia? A daunting task indeed. Hours of replay value await for you.

What are people saying about Okhlos?


"Are you feeling angry? Angry enough to lead a small army as it kicks Zeus in the shins until he dies? Good. Then you are ready." - Rock Paper Shotgun

"And it does so with so much style, with those lovely graphics, that it's hard not to jump in and start playing it!" El Pixel Ilustre

"And the action is fast-paced and frantic. Basically, Homer meets Cannon Fodder." Rezzed 2015 – our 16 favourite games The Guardian

Can we already pre-order the game and get awesome goodies?

Yup! Through the campaign's lower tiers players can gain access to Okhlos' closed beta, which we'll be announcing soon, and to its Original Soundtrack, created by A Shell in the Pit. Through the higher tiers players will have the chance to become one of the game's characters, either as an angry mobster or one of its leaders!

Hey there! This week we are gonna talk about our interactive dioramas, show how the 3D meshes mix with pixel art. Particularly we are going to talk about how we made them.

A little history

It all started at the time we were about to launch our Greenlight campaign. We wanted to do something cool, and show little bit more of the game, but we knew that demos hurt sales, so we our first approach was to do some sort of teaser, something were you could feel how the 3D / 2D worked together, without showing too much gameplay. Not long we ended up with a few prototypes.

The first prototype was a sandbox-oriented single level. To test it, we reached out to a few people that had never played Okhlos before. Their response was not very good. They felt that the lack of objectives was very confusing. We iterated a bit more on this, but we always landed in similar places. Another problem was that were quite a lot of mechanics to learn and not that much chance to include a tutorial in a pickup-and-play single-level teaser.

Ideally, you could choose different units to test different mob configurations


So we discarded this prototype, and the sandbox approach, and we started exploring some more goal-oriented prototypes.

Not long after that we landed in a Colosseum mode, where the player would have to battle wave upon wave of enemies. This turned out to be pretty enjoyable, but we still had the problem of a lack of some kind of tutorial. We figured out that we couldn't throw the user into the level without some basic concepts. Finally, we discarded this prototype as well. It was fun but far from perfect. In addition to this, we were concerned that some players may get the idea that the whole game was going to be that way, merely fighting endless waves of enemies.

Also, at that time, we ran into a new problem: Chrome dropped support of Unity's web plug-in. The teaser had always been aimed to be played in a browser, so this was definitely a setback.

The bright side of this was that, due to the nature of the Colosseum mode, we had the chance to focus more on the combat mechanics. We learned more than one thing doing this and we took them to the main game. Yay us.

So, the clock was ticking and we wanted to do at least something before launching our Greenlight campaign. That's when we had the idea of using Sketchfab.

Why Sketchfab?

We really wanted to show how pixel art and 3D worked together, and there were few options to achieve this (making an .exe was almost out of the question. Nobody downloads tech demos).

Sketchfab, unlike Unity, runs with HTML5 (I think), so we had no browser compatibility problems. Also, you don't need to install any plugins to view a Sketchfab model in your browser, it's pretty straightforward. Finally, Sketchfab has Unity support, which was also a plus for us, since we could use everything we already had set up in Unity to build these scenes faster (as opposed to building them from scratch in 3DSMax).

Unity + Sketchfab

In order to do be able to upload a model to Sketchfab from Unity you first have to download the lastest unity package from the Asset Store.

Plugin

We installed the package in Okhlos' main Unity project. We had a few compatibility problems with some things, but for the most part deactivating things did the trick. The main problem we had, was that we couldn't make a windows standalone build if we had the package content in the directory. This was particularly annoying, but deleting the Sketchfab folder is literally one key down (and a left arrow key, and an enter). So it's not so bad.

Once we installed the Sketchfab exporter we found out that, even though some things were cool, others were very annoying:

  • You CAN'T see how the model looks in Sketchfab until it is online.
  • Automatically, every model is made public for any user to browse. As an artist, I hate this.
  • There are lots of little problems with some textures and geometries.
  • If a shader you are using is not supported, your model will look like a Kandinsky.
  • The plugin is pretty basic, and there is almost no support on the web about using Unity + Sketchfab.
  • You have to set an awful amount of things in the Sketchfab web editor because the Unity Settings are not imported (billinear/point, alpha channel, etc).

Clearly, this tool is not designed specifically to export any unity object, and we are stretching what you can do with the platform, so is not like all of this is particularly Sketchfab's fault.

So, how do we start?

Doing a Pixel Art Diorama

Starting is easy. You only have to put the pieces together. I suggest creating a prefab, so as not to lose information (Unity is notorious for not being that trustworthy with the scene information). Once you have the prefab, you have to select it in order to export it (alla "Export Selected" in max), but it will only export things in the scene, not in the project folder.

Seleccionado

I really don't know the amount of polys Sketchfab supports, and because all our buildings are low poly, we didn't have any problems with the poly count.

Another thing I recommend, is giving the model some context. In our case, because of the Diorama approach, we put a plinth to push the idea a little bit further. Basically you don't have to do anything like this, you only have to do something pretty, and preferably not very big, the navigation in the Sketchfab viewer is not fantastic. It is not impossible, but I can't imagine using the tool as a level navigator (but of course you can do something like that!).

Now that you selected the object, you have to export it with the Sketchfab window. There are not many options here.

ExporterSketchfab


Once uploaded, it will appear in your user models.

Subido

Then, you can edit a few things regarding the materials, annotations, camera, and post effects. All of these are easily tweakeable.

I would've loved if this was all you needed to know, but because we use 2D toolkit for the sprites, the process is quite more complex.

2Dtoolkit considerations

Exporting geometry is easy. Technically, the sprites in 2D toolkit are simple geometry as well (planes), but we had to do A LOT of experimentation to get it right.

First of all, as I said before, if Sketchfab doesn't like your shader, it can turn your model into garbage.

monstrosity

Oh god! Kill him! Kill him!

You have to use (while you export at least) a basic shader. Also, keep in mind that every time you create an atlas in 2dtk, it will create a texture and a material (usually called Atlas0, because of reasons). So, if you have multiple atlases, all with different names, but you kept the default name for the materials and textures(Atlas0), Sketchfab will think that they are all the same material, and you will not be able to change them. A workaround for this is naming each material and texture differently. Don't worry, this brings no trouble at all to the project, you will still be able to update your atlas and it will keep the new names.

atlas0You should rename all of these.

Once you do this, you will be able to use multiple atlases for the model, using the same atlases that you are currently using in the project. You'll need to set the alpha channel of each texture, which is a pain. Also, because of the pixel art nature, you'll have to set all the textures into Nearest (Point in Unity) (they are usually in Billinear in both). This means that it will do no interpolation in the image, and will show every pixel as is.

settingmaterial

Take a look at the transparency configuration. Also, you should switch it to Point (Nearest)

These are mostly the considerations you have to know using 2DToolkit in Sketchfab. However, if you take a close look at the sprites, you'll notice some imperfections. We couldn't find a way to fix this, but because they only show in a few sprites we decided to live with them.

erroresHere, Aristotle had a harsh hair cut. And Plato lost his feet.

So there you have it! You can play with the model settings for cool post effects, lights, etc.

Hope you found this info useful!

A little disclaimer, I'm not affiliated to Sketchfab in any way (or to Unity, but that's more obvious). I just liked the tool, and we had a few questions regarding how we made the dioramas.

We haven't thought of that yet, there is still a long way to go, but my guess would be from $5 to $15.
