[SOLVED] Forge can't read my OBJ model

[myoKun345]

I made a model in Cinema 4D for my mod, UV mapped it and exported it to OBJ format. I registered it in my model class, and when I start the game, it crashes with the following error:

net.minecraftforge.client.model.ModelFormatException: Error parsing entry ('v -500 -6.319035 6.319', line 5) in file '/assets/majyyka/models/wand.obj' - Incorrect format

I can import and view the model in 3DS Max, so I don't know what is wrong with my OBJ file and/or Forge.

Did you use advancedobjectimporter ? If so you should look at the class for the object importer, and figure out if you used bas syntax. I haven't personally used it but I know a bit about it. (I'm a bad artist, I use techne )

[Alix_The_Alicorn]

Also, some open source mods use that class so look at the source of mods like EE3 and Resonant Induction. Maybe also compare your model to theirs.

[myoKun345]

I used AdvancedModelLoader (I was sort of half-following Minalien's tutorial for OBJ models; that tutorial is for blocks and this is an item so it is entirely possible I just screwed something up T-T) and I will look at that just in case. I also looked at Pahimar's code for some reference.

[myoKun345]

Wow this model loader code is barely decipherable to me...

 

Looking at EE3's obj files vs. mine I'm only seeing that his don't have the automatically exported material lines like mine does. I don't think I need it so I'll try deleting it.

 

EDIT: Yeah, no difference.

[myoKun345]

Exporting the obj from 3ds Max results in the crash still happening... but later in the file.

Try deleting the offending line (line 5) in your obj. It might be just Forge being picky.

[myoKun345]

It's not line 5 anymore - see above lol

 

I'm trying to go through and find which ones are breaking it and comment those out. Very tedious and I expect it won't turn out to look good...

[myoKun345]

So, I commented out every face that it crashed on and ended up with this:

[myoKun345]

I've noticed that all of the lines that it errors on are triangles. And I have no clue what to do now.

 

EDIT: They may not actually be triangles, but the lines have 3 "x/x/x"s instead of 4 like the others.

[myoKun345]

Ok, problem fixed, Forge just can't read triangles. Re-exported it from Cinema 4D into FBX (which it has better support for) which I exported to OBJ in 3ds Max.
