obj with mtl and texture import?

KimberSue

Hi, I've been reading the forum but nothing I find seem to help so I want find out if what need to do is possible before spend more time trying to figure it out.

Marvelous designer has a new export obj that include the obj, .mtl and texture (png, jpg). See example image below.

I've tried putting them all in the same folder and all in the same runtime folder but only the basic obj loads. Any thought what else to do?

Thank you

Try opening the mtl file in a text editor (Notepad) and see where it is looking for the texture file to be found. Mtl files are NOT the best at getting textures into different programs. They generally provide only basic info that has a good likelihood of having absolute path information for image mapped textures.

In DS, when the obj is loaded, go to the Surfaces pane and under Diffuse, the box on the left side of the Color line is for loading the texture files. Click on it, select 'Browse' and go to the folder you have the file in.

Thanks, I've tried adding the texture in but all the setting where wrong. My problem is that I can very quickly make wonderful clothing in Marvelous Designer but moving that object with texture setting (texture angles, strength, transparency, etc..) to Daz is pretty much impossible at this time. I had hoped the mtl would help fix that.

This is the mtl file but I don't understand them well enough to even know if the setting might be correct. I added a picture of the dress with the correct setting that I'm trying to move to daz.

There is one thing that might be happening here (it's bitten me quite a few times until I realised what was going on). The .obj .mtl and textures files all work together — you've definitely moved them all into the same folder for import into D|S? The .mtl file you posted looks good, but the .obj file must point to the .mtl file. Open the .obj file in a text editor and look at the very beginning, there should be a reference to the .mtl file. Check that this file name is right, and make sure the file name doesn't have a folder path in front of it. If the .obj file has a wrong reference to the .mtl file, then it'll never find it, and the base colours and textures won't be applied when you import the .obj.

I tried removing the mtllib from in front of island dress2.mtl which is the name of the mtl file but that didn't change anything.

I opened the obj in a txt file and got:

Any thoughts?

DS isn't loading them because it doesn't have a clue where to begin looking for them, all the mtl is telling DS is the name of the textures to stick in the Diffuse & Ambient channels, but not where on you computer to find them.

If the textures are in the same folder as the mtl then you might get away with a simple change, edit the mtl and change map_Kd TSesumII-lace03_2.png to map_Kd "/TSesumII-lace03_2.png", if that doesn't work then you will need to use the full pathway including the drive letter.

Here's an example of the format.

newmtl chrome_grill_front_p07
Ns 0.000000
Ka 0.000000 0.000000 0.000000
Kd 0.203922 0.203922 0.203922
Ks 0.450981 0.450981 0.450981
Ni 1.000000
d 1.000000
illum 2
map_Kd C:\Users\Name\Documents\DAZ 3D\Studio\My Library\resources\Textures\Automobiles\Hunster3D\Car\logo.jpg

I just browse to the Texture location with Windows explorer and copy the navigation bar. It switches format if you click on the folder at the start of the bar.(Win8). On occasion the the length of the text can be too long, then just enclose with quotes. So:

map_Kd "C:\Users\Name\Documents\DAZ 3D\Studio\My Library\resources\Textures\Automobiles\Hunster3D\Car\logo.jpg"
Is also valid.

Hope this helps.

It won't change anything — I said remove the folder path, "mtllib" isn't a folder path, it's the command in the .obj file that tells the importing program to expect a file name. You took out the command, so D|S doesn't know what to do with the (to it) random characters on that line.

One possibility is the file name itself. The .obj file format is very, very old, I'm fairly sure before Windows and the original MacOS operating systems. You have a file name with a space in it, so the file name might be getting chopped short at the space. I've noticed this when I convert meshes using PoseRay, a file loaded as "file name.3ds" becomes "file_name.obj" when I export it. Try going back to your original model in Marvelous Designer and change the name so it doesn't have a space.

Thanks to everyone. It's late and change to the full file name don't change anything. Tomorrow when I am not so tired I plan to try the file name with underscore and/or full file paths.

KimberSue

First I want thank you all for the help you gave me.

Second: As long as the file name when export has an underscore and the uv map setting is unchecked it works very well.

I put a quick tutor up here with pictures: http://imaginative3d.com/export-marvelous-designer-to-daz/
