Most-likely you do not have to change much to adopt it to your game. How long will it take to animate, simulate and render the model in game? Remember there is a small time frame to do everything (not just the one model).įinally what is 'game-ready' for one is not necessarily 'game-ready' to another. Yes, performance aspects have to be considered. Is it a character with closeups or an asset that usually will not appear larger then a few pixels? How many of it will there be? How well does it fit the scene?

Not all options that work in the Blender Editor will work with the BGE.Īlso important is the purpose within a game. For example you can directly use the character (with armature and skin mesh) within the BGE. On characters you often want a skeleton (armature) and animations. In Blender it typically means, there are no modifiers and the materials are 100% compatible. This strongly depends on the game (and game engine) as well as the purpose of the model. Game-ready = you can use it in game as is (without further manipulation). So often you'd have to model the geometry twice, once as a high poly model, and once more as a low poly model, in order to create a baked normal map. Most game models benefits from having a detailed normal map, which uses a low-poly mesh combined with a normal map to represent additional surface bumps. Note most of these requirements only apply to the end result, as you are creating your models, you can use multiple textures, multiple modifiers, even ngons temporarily, until you are ready to export the final model. This ensures that the object can be drawn with one drawcall for optimal performance. Usually a single object has a single material and single textureset(1 albedo, 1 normal, 1 roughtness map for a typical PBR workflow).Use texture size that's appropriate for the size of the object on the screen.Maximize use of UV space, wasted texture space is wasted memory.A lot can be done with shaders and textures these days, so the geometry is likely going to be quite simple.Smart use of triangle budget to ensure optimal performance.Mesh is all triangles or quads(which can be easily converted to triangles), depending on engine.But across the industry it usually means being very aware of the performance impact of polygons and textures and use them as efficiently as possible:
