multiple textures terrain in b3d format

[crivipro]

Hi! I am new in irrlicht, I made a terrain with multiple textures using 3d wold studio and exported it to b3d format. Well, I could load the terrain but only I see one texture. What I missing?

This is my code:

// loadB3D.cpp: define el punto de entrada de la aplicación de consola.
//

#include "stdafx.h"
#include <irrlicht.h>

using namespace irr;

#pragma comment(lib, "Irrlicht.lib")

int main()
{

IrrlichtDevice *device = createDevice(video::EDT_DIRECT3D9, core::dimension2d<s32>(640, 480), 32, false, false, false, 0);

video::IVideoDriver *driver = device->getVideoDriver();
scene::ISceneManager *smgr = device->getSceneManager();
gui::IGUIEnvironment *guienv = device->getGUIEnvironment();

guienv->addStaticText(L"Hello World! You are now running Irrlicht Engine!", core::rect<int>(10,10,200,22), true);

scene::IAnimatedMesh *mesh = smgr->getMesh("media/terrain.b3d");
scene::IAnimatedMeshSceneNode *node = smgr->addAnimatedMeshSceneNode(mesh);

if (node)
{

node->setMaterialFlag(video::EMF_LIGHTING, false);

video::ITexture *texture1 = driver->getTexture("media/isampler24.jpg");
node->setMaterialTexture(0, texture1);
video::ITexture *texture2 = driver->getTexture("media/rock1.jpg");
node->setMaterialTexture(2, texture2);

//node->setFrameLoop(1, 25);

//node->setRotation(core::vector3df(0, 180, 0));
}

//scene::ICameraSceneNode *camera = smgr->addCameraSceneNode(0, core::vector3df(-100, 100, 150), core::vector3df(0, 5, 20));

scene::ICameraSceneNode* camera = smgr->addCameraSceneNodeFPS();


while(device->run())
{

driver->beginScene(true, true, video::SColor(255, 100, 101, 140));
smgr->drawAll();
guienv->drawAll();
driver->endScene();

}
device->drop();
return 0;

}

Thanks in advance!

hmm, the textures should load automatic (or does b3d not?)...
at least this is wrong in your code:

Code: Select all

node->setMaterialTexture(2, texture2);

this doesn't mean setting the 2nd texture, but it's texture layer 2 (in fact the 3rd, bc it starts at 0) and this is not what you want !!!
try it without loading the textures manually (remove the 2 setMaterialTexture lines)...

oh, and please use code tags for your code...

Yes you are right, was just a scene ligth problem I went to 3WDS and set a sun ligth and later could see multiple textures, and commented this lines of code:

Code: Select all

video::ITexture *texture1 = driver->getTexture("media/isampler24.jpg");
node->setMaterialTexture(0, texture1);
video::ITexture *texture2 = driver->getTexture("media/rock1.jpg");
node->setMaterialTexture(2, texture2); 

But now I facing other problem. I have a terrain made in 3d world studio with 2 textures and the textures do not become soft where one finishes and the other one begins, alone a division in straight line between one and another one looks. Please how can I resolve this?

[Acki]

what do you mean by "not become soft" ???
I guess you want the textures fade into each other ???
well, this can't be done the way you try it now...

the technique you want to use is called texture blending or splatting...
unfortunately I'm not familar with this, sorry...

I think there where some threads about this and a terrain editor using Irrlicht in the project announcement forum, but I don't know how much they could help...

[crivipro]

Sorry my friend, my english is not good enough. That is what I want precisely.
Thanks again!

Better yet, use a 3d world studio loader.

http://irrlicht.sourceforge.net/phpBB2/ ... 35&start=0

With this you can open the 3dw files directly (with terrain splating)

[crivipro]

The thing is I can't make collisions, I know that I must use OctTreeTriangleSelector but I can't get the mesh. After load the model with:

Code: Select all

	C3DWScene c3dw;
	c3dw.load(device, "track.3dw", true, true);

How I can get the mesh, like MyMesh->getMesh(0)?

That's all I need now...Thanks everybody!
