Skybox - all right but dont show !?!

[mcunha98]

Based in an example of IRR, i started the first step : put a skybox in my world. Reading about the question i found the AddSkyBoxSceneNode method but i use the method correctly but the sky dont is showed

I need use more code in my "main loop" to work ?

Code: Select all

#include <stdio.h>
#include <stdlib.h>
#include <string.h> 
#include <irrlicht.h>
#include "cinifile.h"

using namespace irr;
using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;

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

int main()
{
	IrrlichtDevice *device = createDevice(EDT_SOFTWARE, dimension2d<s32>(800, 600), 16, false, false, false, 0);
	device->setWindowCaption(L"Resgate do Rebanho");
	IVideoDriver* driver = device->getVideoDriver();
	ISceneManager* smgr = device->getSceneManager();
	IGUIEnvironment* guienv = device->getGUIEnvironment();
	int lastFPS = -1;

	guienv->addStaticText(L"Hello World! This is the Irrlicht Software renderer!",rect<int>(10,10,200,22), true);
	IAnimatedMesh* mesh = smgr->getMesh("C:/irrlicht-1.3/media/sydney.md2");
	IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );

	if (node)
	{
		node->setMaterialFlag(EMF_LIGHTING, false);
		node->setFrameLoop(0, 310);
		node->setMaterialTexture( 0, driver->getTexture("C:/irrlicht-1.3/media/sydney.bmp") );

  	sky->setVisible(true);

	device->drop();
	return 0;
}

Look into the console window: possibly it saying "Couldn't open ... " or you have to see "Texture loaded ... ". Please, show the console output.

Also this is unnecessary:

Code: Select all

sky->setVisible(true);

[mcunha98]

Ok, i delete the setVisible call...
The output window:

Code: Select all

How you see, all textures loaded with sucessfull !

hmm linkoraclehero had this problem earlier when setting the near value of the camera further than 1.0. Try setting your skybox scale to (100,100,100)

Also, you may have z-fighting problems if you set your far value so far away

It looks to me like the software device is having problems rendering 3d objects. The example programs render nothing when using the EDT_SOFTWARE driver also. I'm seeing the same problem with Irrlicht 1.2, so this seems to have been broken for some time.

Ahh, of course, the software renderer does not show skyboxes. Since all triangles which overlap the frustum are culled completely the skybox is always not drawn. So choose a different renderer!

[vitek]

Right.

I don't know what it is, but I'm unable to draw any 3d primitives at all with the software renderer. It works fine if I use an clean SDK install, but if I use my current build it doesn't work at all. :(
