I have mostly finished my foliage system, for the moment.<\/p>\n

I have removed the 4 texture limit, and added the ability to add new textures or texture combinations by height, and vary their density.<\/p>\n

I was making a stupid mistake with the shader, which cost me some time. I was using the camera position instead of the vertex position, and I was wondering why all of my foliage types were changing at once.<\/p>\n

I believe there are still some memory leaks in the shader, and I still have new features to add, such as new texture types and values, and a “paging” texture system. This would allow me to swap out textures as the player moves around the world, so that I would only need to have a small number of textures loaded at once.<\/p>\n

Overall I am quite satisfied with how this worked out, I think it will dramatically improve the look of the terrain. Something that I really like about it is that I can render a LOT of foliage without any major performance problems (and I am running the game through the Unity editor!) this is exactly the result I was trying to achieve.<\/p>\n

The next goal is to add a similar system for trees, rocks, and other larger objects. The problem here though is that they will need to be in the same place for all clients. I intend to research various procedural content generation techniques in an attempt to generate the trees on each client using seeded random numbers. I have decided to move more towards procedural content generation on the client rather than the server, due to the issues that I experienced recently. The game will still be multiplayer, and I will still have a single game world which is explorable and modifyable by all players, but instead of doing most of the work on the server, I will simple be creating seeds and property values on the server, and sending those to the client for rendering.<\/p>\n

I now need to figure out how to create an entire forest based on a single seed, while also only processing the tree objects close to the player. IE, I can’t just generate all of the trees at once from the same seed, there would be far too many.<\/p>\n
