DeleD Community Edition

Hi!

I'm kinda embarassed, that my first post is a plea for help, but I'd quite urgently need one and I dont know where else to turn.

So, the thing is... I'm using DeleD as a middle step in converting .blend files to OGRE meshes (.mesh), and I'm having some problems with textures...

Now, I know the rough process, since I managed to do it a first couple of times, but I simply cant get it working anymore!

T'was something like this:
1. Create a mesh in blender
2. Texture it
3. Export in .obj (settings?)
4. Import in DeleD as .obj
5. Export in OGRE mesh

The problem is, I get no texture in step 4. I can have it textured and rendered in blender no problem, but when I try to put in in DeleD, the texture dissapears. It could be something with blender export settings, but I doubt it. I succeeded in exporting a couple of first meshes w/ textures, but then, it simply stopped working.
The thing is, I dont actually need the texture to show in DeleD, since I assign textures to .mesh trough .cfg files, but it seems that if DeleD doesen't assign some sort of texture layer to .mesh file (which it doesent, since the blender texture isnt copied), the .cfg texture mapping doesent work.
Halp, kitteh?

Well, I haven't ever touched the .obj importer (well I did, once), but have you tried assigning the texture you applied in DeleD again? If you're lucky, the uv coordinates are exported and only the texture got lost.

Also, welcome

From my playings around with obj, I would suggest making sure your textures are in the same folder as the obj and mtl files before importing. (I think that's what I had to do. It's been a while)

Welcome to our forums indeed! Let's separate the two steps:

1. Importing the .OBJ file

Here are the technical specifications of what the importer does:

First of all, REALLY thanks for all the help, I appreciate it a ton!

Well... So I checked the .obj and .mtl files, and while the .obj file has all the references (usemtl), the .mtl lacks the reference to the texture. I'll post the text in .mtl in code below:

In Blender, you need to assign the texture in the UV/Image Editor (UV- or Face-Textures!). Do not use material textures as they will not be exported.

Do the following:
Select your object.
Go into Edit-Mode (TAB)
Select all faces you want to re-texture.
Create a UV-Layer: Press "U" and select a unwrapping method (try Cube Projection first). (This creates the first texture layer.)
Open a "UV/Image Editor" window. (I recommend splitting up the 3D-View to have both in view).
Here select all faces by pressing "A".
Now load the texture by selecting the "Image"->"Open" menu. Or select a loaded one with the dropdown menu.

The selected faces are now textured with the loaded texture.

Now the exporter should export with textures.

You may test your texture assignments in "Texture Face Materials"-Mode (inside the Game menu (Topmost header)). If they show up in "Textured" view they should get exported.

As long as the .mtl file doesn't contain any reference to the texture, importing it into DeleD will not work. From Blender's OBJ exporter source:

No problem.

Its a bit confusing because Blender has two options to assign textures to meshes. One with materials (does not work with most exporter!) and with the UV-Editor on a per face basis. The UV-Editor should always be used for game content or for exporting.
