These two features complicate Blockland’s code tremendously. That means we can’t add game features very quickly. They still have bugs in them (after years of work). They are slow, too - bricks are about 90% of their speed and can do a LOT more (explosions, events, in-game editing).
The two features Kompressor is referring to are Terrain and Interiors.
Instead of disabling terrain completely, what if Badspot makes a toggle option, when shaders are enabled then terrains can not be enabled, but when shaders are disabled, terrain CAN be enabled. This way we can still have the old terrain that we love and use. (Nobots death race) For online games, Badspot can create a new property called "Terrain", the server will use this to check if a game uses terrain and to see if you have terrain enabled. If you do not have not enabled then a message will come up saying you need to enable it, and vice versa. (Badspot could even make it switch automatically!)
kompressor also pointed out that the terrain makes Blockland look ugly, all we have to do is use higher quality textures and possibly a better program that has smoother edges when it renders, like 3DSMax (unless that is Blockland's fault)
My last point is this, kompressor and others say that they are removing a feature but adding in a new one, like taking its place. What about those who do not have a good computer, or are using Intel GMA/HD graphics. Thats not replacing a feature, for them its just removing an entirely good feature that they could actually play on. There are actually good amounts of people who uses Intel GMA/HD to this day, and Badspot and kompressor just removed a very good feature for them.
If my suggestion is a possibility then please get to work on it and don't remove terrain....at least not forever
