****Solved this by my own in the meanhile (see Update 3 at the bottom). But maybe it's helpful for any Googling Googler, so I'm not going to delete.**** (though this post is not even released by moderation right now lol)
**System-informtions:**
HP ProBook 450 G0 (Intel Core i5)
Windows 8.1 64 bit
Unity 4.6.1f1 (free version)
Application built as standalone Windows player
*Hint:*
(For some reasons, like integrated Occulus SDK, I didn't use my original project for debugging and those screenshots, but the example scene from the author of that obj-loader mentioned later)
**Description of my problem:**
My purpose was to make Unity to load a .obj 3D model at runtime into my world. For this I used a parser I found at [everyday3d.com][1].
So ... everything seemed to work fine, I put that scripts into my project and was able to load obj files from my webspace, I even managed to add dynamicaly loaded behaviour from outside. Well so the model gets visible within the test environment of the Unity Editor:
![]()
But when I build it and start the application, the model doesn't appear at runtime. What I get during debugging the development build is the exception visible in the screenshot:
![]()
As far as I can reproduce, the problems begin with
m = new Material(Shader.Find("Specular"));
And yeah well ... I have no clue what happens afterwards. The "Build Agent" directory doesn't exist, when I try to inspect the further "path" of the given exception. I guess that's just some temporary help-code for the Unity interpreter? Anyway my applications seem to not find the Specular shader. I hope someone can help me :/
Update: Hm found something in the output_log.txt of my project (data folder). Can't get something new out of it but maybe you can:
NullReferenceException

at OBJ+c__Iterator0.MoveNext () [0x001e2] in D:\Source\Unity_test4_whereIsMyMonkey\Assets\OBJ\src\OBJ.cs:73
Update 2:
According to information inside the Unity Scripting [Documentation][2], Shaders will only be included into the build, if they were used otherwise in any scene or are stored in the Resources directory. So the next question: where are the standard shaders of unity located? Seems like I have to push them into the Resources folder.
Update 3: Ok, this has been the right clue. Quick workaround: added a new material using the Specular shader into a folder named Resources. Thanks for your attention, anyway!
