Tall Wrold is Resource Heavy

[AlphaFox13]

[12:13:28] [Server thread/ERROR]: Encountered an unexpected exception java.lang.OutOfMemoryError: Java heap space

That was the error i got when attempting to run with only 1G of ram. I wouldn't call being resource a bug however i do think it needs addressing. Here is my proposed solution. In a vanilla report i get:

[12:34:47] [Server thread/INFO]: Preparing spawn area: 63% [12:34:48] [Server thread/INFO]: Changing view distance to 2, from 10

This seems like Minecraft is loading up 10 chunks distance, then taking in to account the render distance, I have no idea whether Tall Worlds runs the same way, however if it does would it be possible to lighten the load on lower end PC's by considering render distance Before Loading chunks rather than after. I am going to install a linux operating system in the mean time that way i can free up my ram (stupid windoz)

Error reports are below

[ajthemacboy]

I know this isn't really the right place to ask but I didn't want to create another separate issue for this.

How did you compile CubicChunks? Gradle and gradlew build are not working for me, and I really can't figure out why.

Also, CubicChunks is still in its very early stages; optimizations have not been added yet. So yes, this is an issue, but it probably won't be fixed for a while.

[Razaekel]

Tall worlds is going to be resource heavy compared to vanilla Minecraft due to the larger amount of data loaded. At 32 chunk render distance, vanilla loads 67,600 cubes. Tall worlds will load 274,625 cubes at maximum. That's going to be a 4x increase in memory requirements. We'll work on bringing it down as much as we can.

[cuchaz]

We added some memory optimizations in the last release that should help with this. The next thing to do is occlusion culling which should drastically cut down on the number of loaded cubes at a time, but it's a big change, so it won't happen any time soon. I'm closing this issue for now.
