What file type are you using? Fbx or OBJ or? There are many assets in the asset store to help load files into a unity project.

@mark_grossnickle
i'm currently importing obj using https://www.assetstore.unity3d.com/en/#!/content/49547
able to import obj successfully in editor but not in hl. always crashes when i 'select' the obj file in onedrive window. i've checked that the filepath is the correct one.

private void SetLoadFile(StorageFile theFile) 
{
        if (theFile != null)
        {
            OBJLoader.LoadOBJFile(theFile.Path);
        }
}

any suggestions?

@felsiska I do not know off hand but if you run while connected to visual studio what errors do you get in the log files?

@mark_grossnickle found out that it's due to the missing material shader. managed to import in without material now. any suggestions on how to use the TextureLoader script so that i can import materials too? or do i have to use fbx importers instead?
thx

@felsiska I don't think so. I think we import OBJ files with the materials baked in.

@pnolen Can you confirm? Or do have to load textures manually along with the OBJs?

felsiska

@mark_grossnickle seems like it can't get the correct texture mapping. it created a new material accordingly but only missing the albedo texture. but works fine in editor

Sorry, you are right. I am looking at @pnolen's code. He is loading the texture externally.

Here is a snippet:

`Texture2D texture = null;

            if (!string.IsNullOrEmpty(modelTextureName))
            {
                WWW textureWWW = new WWW("file://" + Application.persistentDataPath + "/" + modelTextureName);

                yield return textureWWW;

                if (string.IsNullOrEmpty(textureWWW.error))
                {

                    texture = textureWWW.texture;

                    if (texture) LoadedTextures.Add(texture);
                }
                else
                    Debug.LogWarning("Failed to load texture " + modelTextureName);
            }`

You can then set the texture on your material using
mat.SetTexture("_MainTex", texture);

Assuming your material/shader has a MainTex property.

@mark_grossnickle I'm loading the texture from another function too for now. thx lots

Hey @felsiska would you mind giving me some tips or share your code?
