Unreal Engine 4 - A Boy and his Kite Demo Assets
Epic Games公司在2015年GDC会议上演示发布“一个小男孩和他的风筝”资源包。
关于这个包：
每个资产已使用真实世界物体的照片创建。
我们的流程：
对于较大的资产，比如岩石，地砖，悬崖和树干，重建是使用一种称为photogrammetry的技术直接进行的。
这些资产通过专有的'去照明“流程，使它们适合于在任何照明方案。反射和粗糙贴图可以重新创造，以充分利用虚幻引擎4的基于物理渲染架构。最后用了法线贴图，碰撞等。
对于植物如花卉，灌木和草，我们使用的颜色校准参考摄影拍摄的素材，更加准确地建模和贴图这些模型。

Epic Games has released assets from the “A Boy and his Kite” Demo that was demonstrated at its GDC 2015 session. The pack is free, but requires and Epic Games account.
A collection of realistic assets from Epic’s Open World demo shown at GDC 2015. Use them to create new levels or add them to existing ones.
About this pack:
Each asset has been created using photographs of a real world object.
Our Process:
For larger assets such as rocks, ground tiles, cliffs faces and tree trunks, reconstruction was performed directly from photographs using a process called photogrammetry.
These assets were then put through a proprietary ‘de-lighting’ process to make them suitable for use in any lighting scenario. Specular and roughness maps where then created to take full advantage of Unreal Engine 4’s Physically Based Rendering architecture. Finally game-optimized assets were generated with normal maps, LODs and collision meshes.
For vegetation such as flowers, bushes and grass we used color calibrated reference photography shot in the field to more accurately model and texture these assets.
