Hi kaedroho,
I have been using blitzwerk terrain for a while now and absolutely love it. I use it in all my 3d projects.
I think however there may possibly still be a bug with deleting and loading terrains. my programs seem to crash a lot when deleting terrains.
sometimes they will delete and load again and work for a short while before crashing.
I'm not sure if its a bug or user error so i've modified your example project...
BLITZWERKS TERRAIN 2.02 EXAMPLE - TERRAIN LOADING
to try and highlight the problem.
here's the ammended code illustrating the problem
//BLITZWERKS TERRAIN 2.02 EXAMPLE - TERRAIN LOADING
//CREATED BY KARL HOBLEY (KAEDROHO) http://www.blitzwerks.co.uk
//CODE BELOW MAY BE USED IN COMMERCIAL AND NON COMMERCIAL PROJECTS
//CREATED AND TESTED WITH DBPRO 7.5
//This demo shows how to load a terrain. As you can see, the code is alot simpler before. And the terrain loads about 10x faster (300ms normal, 30ms load from file)
//The file came from demo 3. I simply added BT SaveTerrain g_TerrainID,"Terrain.blitz" straight after the Build terrain function.
//You can load/save terrains with parts excluded aswell. I thought that I should load the full terrain with 3 LOD levels to demonstrate the speed.
//The file does not store Textures or detailmaps.
//I designed the file to use continuous read/write for superfast loading and saving.
//The load terrain function does everything between Make Terrain and Build terrain, so changing the heightmap/scale/etc is impossible unless you make a new file.
//CONTROLS
//ARROWKEYS AND MOUSE - MOVE
// F1 - WIREFRAME ON. F2 - WIREFRAME OFF
//Setup
