ITerrainSceneNode troubles

[Epsilon]

hi, i am exploring in the heightmap terrain implementation of irrlicht but i cant get it to work, it crashes the application when create the terrain with addTerrainSceneNode.

IDE = M$ VC
OS = Windows XP
IrrVer = 0.4.2

i only want to see the terrain in the screen. for now.

see the code:

video::IImage* texture = driver->createImageFromFile("MapTexture.jpg");
video::IImage* heightmap = driver->createImageFromFile("HeightMapTerrain.jpg");
video::ITexture* detailmap = driver->getTexture("detail.bmp");

// here crash
scene::ITerrainSceneNode* Map = smgr->addTerrainSceneNode(NULL ,NULL, texture, heightmap, detailmap, core::dimension2d<f32>(10.0f,10.0f), 200.0f, core::dimension2d<s32>(64,64));

any idea?

thanks.

In my case this works when texture sizes are 64X64.
With large size 256x256 have no success.

[LordNaikon]

what did you mean with no success

you got a error message? loading an hieghtmap wit 256x256 take a lot of time! maybe your computer is to slow to calculate that. when i add an triangle selector for collision detecting... it took almost infinite time.

I thought the terrain renderer in Irrlicht is in a buggy stage anyway at the moment?

[etcaptor]

Yes, my PC is slow /P3 800/, and I use triangle selector. Mabe my patience is not enough.
I know that terrain randerer is buggy for now, but want to test some cases related with my futures plans.
