[fixed]Tiling problem with COLLADA

[lucifervrn]

Hi, all!
I have a problem with loading object with tiling texture in irrlicht from dae file.

The sample file -


sample code:

Code: Select all

#
#include "irrlicht.h"
 
using namespace irr;
using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;
 
int main()
{
 
    IrrlichtDevice *device =
            createDevice( video::EDT_OPENGL, dimension2d<u32>(640, 480), 16, false, false, false, 0);
//createDevice( video::EDT_SOFTWARE, dimension2d<u32>(640, 480), 16, false, false, false, 0);
 
    if (!device)
            return 1;
 
    device->setWindowCaption(L"Hello World! - Irrlicht Engine Demo");
 
    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();
 
    IAnimatedMesh* mesh = smgr->getMesh("D:/3Dscene/tail/test.dae");
   //IAnimatedMesh* mesh = smgr->getMesh("D:/3Dscene/tail/test.3ds");
    if (!mesh)
    {
        device->drop();
        return 1;
    }
 
     IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );
    if (node)
    {
        node->setMaterialFlag(EMF_LIGHTING, false);
   }
 
    smgr->addCameraSceneNode(0, vector3df(0,50,0), vector3df(0,0,0));
 
 
    while(device->run())
    {
            driver->beginScene(true, true, SColor(255,100,101,140));
            smgr->drawAll();
 
            driver->endScene();
    }
 
    device->drop();
 
    return 0;
}
 

When i export model from 3dsmax to 3ds i got:



When i export model from 3dsmax to dae with openCollada i got:



but with software render i got correct:



You can also check it using example 09.Meshviewer from irrlicht.
Try to load my dae file with software, burningvideo and opengl driver.
dae file - http://rghost.ru/37002696
directX driver works same as opengl.

all of that i try to do with irrlicht 1.7.2 with CColladaFileLoader from 1.8.0 (from svn-4093)
previous versions of irrlicht simply do not load textures from dae files.
and also i try on irrlich from svn-4093 and have same result.

That is strange...
I loaded the mesh in blender and it loads fine, Meshviewer it looks buggered, so to me it seems that somehow the texture repetition is clamped in the y axis.
EDIT: The problem possibly lies somewhere with the way Irrlichts OpenGL and DirectX driver together with Collada, handle texture repeat in Y axis just not sure where yet.

Large amount of troubles...

First the material type it uses is video::ETC_CLAMP - which is correctly displayed in OpenGL and probably not supported in the software renderer (so it uses repeat instead and gives you the result you want).

edit: OK, sorry - seems I've read documentation wrong there. Wrap mode NONE is same as ETC_CLAMP_TO_BORDER - but NONE is not default when no wrap mode is set as I expected. Didn't see this at first as it wasn't documented in the fx_sampler_wrap_common section, but only in the collada_reference_card. So default is "WRAP", so we can fix this in Irrlicht (and maybe also add support for the other modes which seems to be missing so far). I'll change it.

Fixed in latest trunk version (r4103). We still set the wrapping modes for all textures in a material together (to the same value) - could be that's another missing feature, but for you case it should work now.

Yeah, multi-texture support needed another level of indirection IIRC. Some things were fixed already, but since most materials don't need special texture setup for layers 2+ it was not the important stuff to fix for collada files. I guess adding clamp in SW renderer would also be easy

[lucifervrn]

yeah! it is fixed!
thank you very much!
