How to create 3d terrain with Blender 3d Render

This quick tutorial will show you how to create a 3d terrain with Blender 3d Render. This tutorial assumes that you have already known how to use the Blender’s basic features such as switching from the edit mode to object mode and etc so it won’t show you those steps anymore. If you are not familiar with those features then you can read my previous tutorials about them.

Follow these quick steps to create your first 3d terrain for 3d game or whatever purpose it may serve.

1) Start a new Blender Render project and delete the default cube.

2) Create a Mesh Plane and resize it to 10 time the original size.

3) Switch to edit mode and subdivide the plane for 5 times.

4) Press the A key to deselect everything then enable the Proportional Editing mode under Proportional Editing and select Random falloff under Proportional Editing Falloff (The one which is next to Proportional Editing button).

5) Make sure you are in the Vertex select mode. You can either select a few vertexes with Shift-Right Click (or press the B key then select an area) or just Right Click to select only one vertex. Next press the G key, then Z key and type in 0.5 or -0.5 to move the vertex(es) upward or downward to create a mountain or an alley in the new 3d terrain. You can use the mouse wheel to increase or decrease the area of influence of those vertexes.

6) Change the light to sun light.

7) Divide the 3d window into two part horizontally. Switch the left 3d window to UV/Image Editor window then create a new image and name it ‘Terrain’. Next switch the UV/Image Editor’s mode to Paint mode.

8) Next select all the vertexes on the right 3d window and then press the U key to select UV Mapping Unwrap.

9) Change the 3d window from Edit Mode to Texture Paint Mode and it’s Viewport Shading to Texture then add an Ambient Paint Slot (anyone will do because we will change it later).

10) Create a new material and a new Texture and then assigned the new terrain from the UV editor to that new texture and uploaded a texture you have downloaded from the web (let say a sand texture) to this project.

11) Now you can start to paint on the 3d window, you can adjust the brush size and the brightness of the texture from the tool editor on the left of the 3d window.

12) Next add more textures you need and continue to paint on the terrain.

13) After you have satisfied with your terrain you can then adjust the camera angle and render it.

14) Save the image and the Blender file.

15) Below is how the 3d terrain looks like.

The blender render 3d terrain is only good for not so high quality gaming graphic, if you need a realistic looking 3d terrain then you should use the cycles render instead.

Which software do you need to create game graphics

There are lots of free and paid software around that we can use to create game graphic, I particular like these three softwares, Blender, Inkscape and GIMP. I use Blender to create 3D game graphic, use Inkscape to create 2D game graphic and use GIMP to draw simple graphic which I can then edit on Inkscape and Blender.

GIMP is pretty easy to master and you can start using it after a week of training, gimp is use more on photo editing job but creating simple graphic is also not bad at all.

Inkscape is use mainly in creating 2d game graphic, it has lots of features so it will take a while for a beginner to master it.

Blender is a powerful graphic creation software which we can use to create 2d, 3d as well as gaming landscape for our computer game. Blender creates graphic which is close to reality and is a must for game developer to get this tool and starts to create great product.

Game creation takes time and lots of brain energy, if you are a game developer then you must good at both coding and graphic creation. Those three softwares above are just the beginning to your game development journey because as time goes by you might even need to learn autocad or other sophisticated computer graphic generation software which will cost money, therefore game developing business is not an easy business after all but it is fun when you see you game being plays by many users online! That just make you feel happy about it!
