[1.12.2] [Solved] .obj Tesselating block model Error & Texture error

[GooberGunter]

Hey, I'm trying to load a model and I'm getting the following error when loading this model. This is my first time rendering an obj, I don't know if this is because models can't have more than 4 vertices, if there's something wrong with my .obj model, or if I missed something in the code.

The crash happens when placing the block

Ugh, It's because I didn't triangulate the faces...

[GooberGunter]

Update: so I got the model to load, but when the block's texture was being loaded, I got the following error, this one I can't figure out

Edit: after doing some googling, it looks like forge's object loader doesn't support uv mapping yet, is that right?

The ObjLoader does support UV-mapping.

If you mean the "key x is not supported, skipping", you don't actally need those in the .mtl. You should be able to remove them without any effects on your nodel.

[GooberGunter]

Ah ok, then perhaps my problem lies in this line:

[18:20:11] [main/INFO] [FML]: OBJModel: A color has already been defined for material 'Material.001' in 'grandsorcery:models/block/crystal.mtl'. The color defined by key 'Ks' will not be applied!

[GooberGunter]

That’s an error I got when loading a .obj that didn’t have triangulated faces. Now the texture isn’t showing up

[Matryoshika]

Can you post your .mtl file?

Also, what be sure that the normals for your model are correct.

[GooberGunter]

Yeah, here it is, also what's the easiest way to check normals, I've only been making models for about a week or two now.

crystal.mtl

 

Edit: I’ll recalculate the normals in a sec

...

You don't have a texture...

Textures are linked in the .mtl file, under a "map_Kd" key.

Likely caused by an unsuccessful UV-mapping. It was never actually "added".

Here's an example of a .mtl file with mapped textures.

 

Oh, and for the future, please paste the contents of files like this to pastebin/github gist.
Downloading (possibly malevolent) files from strangers can be off putting.

[GooberGunter]

I had a feeling that was the problem, the tutorials I've seen for UV mapping haven't been the best for learning

 

 

Of course, I'll keep it in mind next time, sorry about that, in fact, depending on the last time I updated my repository, the file might be there
