Terrains Gone Crazy in 0.14

[krama757]

Porting over from 0.12 to 0.14 I had no problem compiling. But it seems the terrain algorithm has been changed.

When I draw the same heightmap I did in 0.12 in 0.14 the heightmap is crazy. It seems only 1 row of LOD patches is drawn or something.

Here is a pic:


Here is the code:

Code: Select all

pTerrain = irrSceneMan->addTerrainSceneNode("./data/maps/HeightMap2.jpg",
															0,-1,									//bleh
															vector3df(0,0,0),						//position
															vector3df(0,0,0),						//rotation
															//vector3df(8,4.4f,8),					//scale
															vector3df(8,4.4f,8),					//scale
															SColor(255,255,255,255),				//default color
															//3,ETPS_9);
															3,ETPS_9);
	pTerrain ->setMaterialFlag(EMF_LIGHTING, false);
	pTerrain ->setMaterialTexture(0, irrDriver->getTexture("./data/textures/maps/HeightMap2.bmp"));
	pTerrain ->setMaterialTexture(1, irrDriver->getTexture("./data/textures/env/bumpy.jpg"));
	pTerrain ->setMaterialType(EMT_DETAIL_MAP);
	pTerrain ->scaleTexture(1.0f, 100.0f);

Any ideas? Spintz? Guys?

have u seen this thread?
http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=10116
perhaps the 2^n+1 is something for u?

( I havent upgraded yet.. Seams to me that 0.14 is somewhat grumpy -especially the needs to recompile if AABBox shal work correctly..
NICO says that 0.12 header must substitute 0.14 header.. the recompile..
I have NO idea how to set up dev to recompile the dll
waiting for 0.14.1 :)

Yeah aabbox need recompiling and something is really fubared with the terrain when it's large. I have no problems with the terrain in IrrSpintz. I've ported my current terrain scene node from IrrSpintz over to Irrlicht-0.14 and the terrain is still messed up. There are some thing really wrong with 0.14, and I'm not positive it's the terrain, at least not directly. I'm thinking the terrain just makes the problem noticeable.

Hmm, so stick to 0.12 until things get cleaned up, got it

THanks guys.

This problem should also happen in Irrlicht-0.12. The problem, I believe, is that Irrlicht only supports 16 bit indices. So if the vertex buffer has more than 65536 vertices, strange things will happen.

Nope, using the same code works fine in IrrSpintz 0.12.
