Hi Guys
I'm revisiting DBPro after a while and I'm having a problem with a current project.

I have created a detailed building as a .3ds object and textured it as required, My Editor displays the object in all its glory, and independand viewer displays it perfectly as well, however DBPro is just showing it up as Black. I've tried Lithunwrap to convert it to a .x file, but this inverts the objects X coordinates (mirror) and still displays it as black even though Lithunwrap details and shows the correct textures.

Any Ideas whats wrong and how to fix it?

1. Have you tried to set the object preferences?
2. Have you set the ambient light level?

It's possible that you have somehow textured the faces on the wrong side. Try scaling your model with a minus sign.. scale object -100,-100,-100. If it is textured on the wrong side it might be an idea to flip all of the faces in a modeller.

Also, what editor are you using? Avoid using .3DS files in DBPRO; it works better with Direct .X files.

Anyway, the FVF format of exported model could be the issue; when DBPRO tries to load the UV coordinates, it cannot locate them in the file, but your editor and viewer can.

Hi Guys
@jobromedia, My Scene has several simple objects, cubes etc. as place holders for the detailed objects, these are all textured and illuminated correct. its only the detailed objects I'm having issues with.

@Pincho Paxto,The textures and faces are all correct, as I said Lithunwrap loads the object and displays it correctly.

@Chris Tate, It's an old version of LW3D, I have to export to .3ds as it doesn't support .x, I then use Lithunwrap to create a .x, then in DBPro I save it as a .dbo object.

The code is very basic, purely a 3D product demonstration...
[ ] set display resolution
[ ] load objects
[ ] position objects
[ ] add skybox
[ ] do camera movements loop

Is how I usually set it up.

Are you using TEXTURE OBJECT objectNumber, imageNumber? Or trying to let the texture automatically be placed on the object? If the latter, try making sure the texture is in the same folder as the object, or use TEXTURE OBJECT objectNumber, imageNumber. The image, itself, is not stored inside the object's file.

P.S. resistance is futile...

Thanks zeroSlave, I have managed to partialy fix the problem.

It appears that my textures aren't getting loaded correctly. I now have an object that has my default luminous pink texture (used to highlight errors) instead of the desired textures.

1.) These are now stored within the same directory as my object.
2.) Lithunwrap appears not to be exporting my object correctly, so I'm looking for another exporter at the moment.
3.) Last option would be to write a routine to convert the objects automaticaly into the .x or .dbo format

P.S. tell Holmer I said Hi

If objects appear black, 9 times out of 10 it's because they're not textured. If you're not using the texture object command, it's because DBP can't find the texture when it tries to load it automatically. Put the texture in the same directory as the .X file and it'll probably find it. If it doesn't, your model may contain the wrong absolute or relative paths. You'll need to get these right!

That's odd. Is there a chance that the file names of the images were swapped somehow? o_O Or, even as Fallout stated above, the image file paths may be incorrect in the model file. I would suggest doing this:



This would likely solve your issue. I personally think using the TEXTURE OBJECT command is a good habit.

If the X file is a text X file just open it in a text editor such as WordPad and search for file names (I usually search for a double quote " or similar). You'll know what the file expects then.

@zeroSlave, using texture object would completely texture my object with just one texture, wouldn't it? I have several textures in this object, walls, floors, roofs etc.

@GreenGandalf, good to see your still around I hope you've finally updated your PC by now!
The exporter i'm using has the option to create a text .x file but it appears to have completely wrong file names for some reason?
e.g. my image is "GreySlate.jpg" is called "Roof", which is what I called the material in my 3D editor! Should I change this to "GreySlate.jpg"?

I don't remember needing to do this before"

My method is to load the object in Blender, select all faces and do a "Smart UV Project" unwrap (U).

Then, I apply a material/texture (use as both) and export to .X format.

As long as the texture file is in the same directory as the object, the texture should then load.

D.D.

Yeah, you're right! I didn't realize you were using multiple textures on the object in question. If I model a level, I typically model it in segments and export and import individually.

Quote: "my image is "GreySlate.jpg" is called "Roof", which is what I called the material in my 3D editor! Should I change this to "GreySlate.jpg"?"

Not sure... But if the image name is "GreySlate.jpg", then there should be something in the .x file such as:
TextureFilename {
"GreySlate.jpg";
}

If it says:
TextureFilename {
"Roof";
}

Then you'd have to change it.
