Tittle says it all. Can I change the world/terrain generation size? Or I'll need to model the entire map? ;w; |

Load a heightmap for different sizes is best method. The texture resolutions will decide how big and also how many polygons it will become. I normally use 512x512 size to get almost 500k polygons and good framerate although with occlusion culling can go up to 1024x1024 for 2 millions polygons if I want at around 200 fps still. Maybe something in between is best fit while using OC. If your loading low res heightmaps (512x512 or lower) then you most likely will see the terracing effect on the ground - its from low res texture info on 'png' and 'jpg' files. I tried 'raw' but not much difference so only solution in this case if for the code to be changed to get the average height from a much higher texture file size like 4k and then be able to adjust the size like 1/8, 1/4, 1/2 or 1 as you like to reduce the polygons back to a reasonable level from taking an average height from multiple pixels instead of 1:1 only currently. Niko will have to add this in - was thinking to get the code for him but this already exists in the Irrlicht code anyways...should be easy for him although at Niko's current rate might never be done...I might have to do this myself... You can also try smoothing low res textures using GIMP or photoshop will help a bit - I use GIMP denoise which helps and also for large hills and low valleys make sure to use full 0-255 black to white variations in the heightmap to reduce the terracing effect. |

I really don't understand. You all use 3D engines, which means you work with 3D models inside your projects. Why not create the terrain in your 3D software? It allows you to have control over everything, including polycount, texture mapping, and all other aspects. |

SamGrady The terrain tool in copper cube has some features with allows you to work in the terrain during the development. I'm sure i do something wrong and didn't know all the secrets of Copper Cube but i would really like to know how i can tile mapping an importet terrain mesh inside copper cube and plant gras and other things? How this work? |

Sometimes you need to change a texture or flatten some polys to place another object. I made a lot of terrains outside copper cube and you are right you have in an 3D program much more possibilties. But the problem starts after importing it in any game engine and you need to change something. |

@ ryandavanzo my solution for you is make the terrain big and then flatten the terrain on the sides you don't want to see. Make a plane cover the areas you dont need. |

Some screenshots would also help to see the problem. If you terrain is to small or what ever and you don't want to change it scale the rest smaller

I agree with @SamGrady... Copper Cube can create and allow you to edit the 3D terrain as you see fit. Adjust the size, sculpt it, change the textures, generate trees and add grass... it's all in there. And the documentation explains how. I think Niko did a great job... Copper Cube can easily make the 3D environment for all the action you want to put into your game. From inside a single room to an entire kingdom... Your imagination is the only limit! |
