.x Model - No Texture

Posted: Tue Jan 23, 2007 11:38 pm

I'm creating a small game for school using Irrlicht.

I've loaded in an IAnimatedMesh as the level and followed the Collision Detection Tutorial.

No matter what I do I cannot get the level mesh to show the textures I've added. It also comes out all white. I've been searching for weeks now and can't solve the problem. Help!

The model was created in Maya and exporting to .x format. The texturing was also done in Maya.

Could you post what shows up in your console as well as a screenshot? It would definately help. Since you have no lights I dont think its a lighting problem...the only other thing I can think of is that the program cannot find the textures and your default model color is all white.

Hi kgorsky!
I think Irrlicht engine can't find your textures, may be the exporter plugin from the Maya. You can export the model in the Maya to .x with the textures and in the .x don't include the path of textures. You can find in the .x find to check these problems. Good luck!

So I had the FOG turned on and that's why everything was white.

here's the screen shot with the FOG turned off:

whatevernodename->setMaterialFlag(EMF_LIGHTING, false);
unless you plan on using lights

the fog can be fixed by doing something like this

Code: Select all

drv->setFog(SColor(255,140,140,140), true, 2200, 3300, 1.0f, false, true);

The fog isn't the problem... I can get that to work... it's the non-textured terrain model...

I tried: whatevernodename->setMaterialFlag(EMF_LIGHTING, false);

I had tried this before with no effects.

I went through the .x file in a word editor and replaced the texture paths and I still got nothing.

In the console info I posted above, what does "Could not open file of texture:" mean...

yeah the same problem and i noticed that (in irredit also) even if u tried to
->setMaterialFlag(EMF_LIGHTING, false);
it will not appear i added lights in irredit and the textures appeared it seams u must add light so the textures appear try it :wink:

have a look at my IrrEdit Scripts posted in the IrrEdit Section of the forum.


I have a few useful ones posted and for the lighing to make it "Toggle" on and off, just take my lighting script and follow the scripts Niko includes in the package , modify it similar , and you now have a toolbar entry to toggle lighting on and off :)

Maybe you could post one of the models to see if that causes the problem. The X importer doesn't handle all X varieties...

I had experiencing a similar problem exporting from Blender

Maybe the solution could be the same:
Open your .X on notepad, and then locate all the image citations on the file, (by extension: .bmp, .jpg etc).
In my Blender exported models, there was something like "picture.bmp.001"
I just take out this .001 and the model was displayed correctly on the screen.

I had similar problems with .x meshes exported from blender, also I noticed that when it finally did display the textures it slowed the framerate to the 60's when it was always in the 100-200's before. I found that if I didn't use the texture path in the .x file and simply manually assigned the texture in the code of my project it worked fine (Im unsure if it was a problem with the irrlicht .x reader or with the exporter for blender).
