Here we finally put together the heightmap design process for whoever has the previous experience over Earth Sculptor.

Some Nice Features For The New Heightmap Terrain System

1. Large Terrain Size- around 9 times of iClone4 terrain size
2. Using multiple texture tiles instead one big texture image, save memory space
3. Much better rendering performance when LOD on (Ctrl-L)
4. Fast picking, easier to apply plantation (grass, tree), snap or walk on terrain, and terrain physics collision
5. Better self-cast shadow quality
6. Keep high texture detail in close view
7. keep high texture detail on vertical surface, such as cliffs
8. Future Terrain Expansion - connect height map terrains to form a bigger terrain; or endless terrain navigation


Here is the design procedure


1. Generate 3D Terrain from EarthSculpter, with map size 513x513



2. Export either OBJ or gray scale height map

You can use either obj or jpeg heightmap, we suggest you use obj for better detail

* Approach A: Load OBJ as the terrain mesh for iClone5 (smooth, higher detail)
* please don't turn on other settings, only "center on origin"



* Approach B: Load Height map (png, jpg, bmp) as the terrain for iclone5 - this can be easily edited by image editor


3. Use Earth Sculpter to create the color Mask file for 4 terrain textures

>>


4. Save map, you will see all related texture maps are created in the same map folder
- the xxx_d.png file is the mask file using RGB+Alpha to keep the 4 color channel information




5. Edit the INI file, please see the sample terrain file

6. Under iClone5 Terrain tab, press Alt-Shift-J to load Terrain defined in the INI file

Supported Image Formats: JPEG, PNG, BMP
