Moho Forum

I have drawn a very simple shape in wings and when i import the file it comes out black and white and no colours are working they just come out as black.

Can anyone help?

Thanks to anyone that does

The problem is most likely that the "edges" Moho is applying to the 3D shape are too fat (way too fat). First, try running the Scripts->3D->Auto-Scale menu command. This can often fix the problem.

If that doesn't solve it, double-click the 3D layer in the Layers window to bring up the Layer Settings dialog. Go to the 3D tab and make the "Edge offset" value smaller. If you take the value all the way down to 0, then Moho will not add any edges at all to the 3D shape.

It still isn't working

Can anyone help???

Do you have someplace you can post the OBJ file to and give us a link to it? Or, you can email the file to support@lostmarble.com

couldn't you post the obj instead?
cause i don't have wings (and i don't plan to get it)

OK Dan, I looked at your file in Wings 3D. When I export as OBJ and import into Moho, it looks pretty close to correct. I think I misunderstood the problem you were having.

Are you talking about shading? The object looks totally black and white when you import it into Moho because:

1. The object is white in Wings 3D (you haven't applied any colors).

and

2. Moho does not support shading on 3D objects. Moho's 3D layers only support displaying a 3D object with flat shading. If you're expecting to see different shades of color based on 3D lighting, that isn't an option in Moho. You can use a separate program to compute lighting and "bake" it into a texture, but Moho doesn't do lighting itself. One such program is called gile[s]:

Well, there is a trick to make shading on 3D-objects in moho. If you add a moho-shading effect to the 3D-object in one direction, and then put the 3D-object in a group-layer and add a shading-effect to the group-layer, and then put it in an other group-layer and add a shading-effect, and so on... If you have different amounts of shading on the object from different angles, then you can make it look good.

But in general it's easier to use gile, as LM recomended.

I can't use Gile[s] because you cant export in the demo version. Is there any other free ones out there??

When i add materials to the faces and then import it to moho, the whole thing is invisible

What now?

Can you show us the new file?

Is it because i only have the demo version of moho?

Hi Crazy Dan,

Here is a screen snapshot of your wings file, imported into moho, after using wings3d (and gimp) to apply some arbitrary textures:

When I get home from work tonight, I will go through the steps I used to get the textures into the model and post them here.

I don't believe that moho limits you that way in the demo version, but LM will correct me if I'm wrong.

Crazy Dan,

It looks like you applied the "_hole_" material in Wings 3D to all the surfaces of your object. I've only dabbled with Wings 3D, but I think the hole material is meant to be used for transparent surfaces. For example, instead of actually cutting a hole in a wall to create a window, you could apply the hole material.

When you export it as OBJ, Wings 3D excludes all polygons that have the hole material - in this case, that means all the polygons in the model. Basically, the resulting OBJ file is completely empty - that's why you see nothing when you import it into Moho.

And no, this has nothing to do with the demo version of Moho. The demo version is fully functional - the only limitations are the DEMO watermark on rendered output, and exported SWF files are in grayscale only.

Here is what I've done to add textures in wings3D so that I could import them into moho. Keep in mind that these textures are "flat", and to get procedural textures you'll have to use something like gile[s].


1. do a "ctrl A" and select everything. then right click, and choose "UV Mapping"
2. more windows will pop up. I'm not sure why in your example, but it seems to put the box into one, and each cyllinder into another.
3. click on each face, and right click to assign values like "AuvChart1-9". This will help you later keep the faces separate
4. after you are done, right click and choose "Continue" -> "Unfolding"
5. wings3D will then show you a 2D diagram of a portion of your model unfolded.
6. Right click and choose "Create Texture". I bumped up the size to 1024x1024 since I thought I might zoom in.
7. Close the "AutoUV" window(s).
8. choose "File" -> "Export" -> "Wavefront(.obj)" and export the model
9. Save your file too, in the regular wings format.
10. Look in the mtl file for a line like "diffuse3.tga". Now, using a bitmap editor of choice (I used gimp, but photoshop, or anything else that opens targa files will work) edit this file. Fill with textures of your choice.
11. Now, inside moho, import 3d object, the .obj file that is created. Your textures appear on your object!

Let me know if this isn't clear, or if you have any problems.

Good luck with wings3d "texture on a stick"!
