Reptiles: In Hunt runs on the popular game engine - Unity. we are able to get excellent graphics and performance thanks to the techniques used in AAA games.
Environment
The game offers rich and detailed vegetation. This effect is achieved, by using GPU instanced grass. This means that we are able to render a large amount of grass without losing the game's performance. Custom grass and trees shaders add a translucency effect to the leaves and grass.
Another technique to add more detail is 3d sprites - impostors. This technique is used for large objects like rocks in the far distance. Impostors are 2-dimensional sprites, which look like 3d models. They maintain perspective and react to light. Thanks to this technique we can generate very dense and detailed far plans with many plants in the game.
Physics
Another interesting technique taken from AAA games is an active ragdoll. Thanks to this technique we can mix death animation with physics. A common problem of using death animation itself is the collision with a random wall. Such a model can penetrate it. Pure ragdoll may be unrealistic or may cause to fire model into space when in contact with a wall.
Animations
In the production of Reptiles: In Hunt, we use many external tools to support our work. One of these tools is UMotion, which allows us to create advanced animations directly in the game engine.
This increases our effectiveness in working with animations.
