What Makes A Good Submission/The Models Resource
Contents
The Model
Textures
Does it have all of the textures included? Sometimes model editors only copy the texture that is immediately applied to the mesh. Make sure to get all of them, even if the textures aren't copied when exported.
Texture Format
The Models Resource only allows textures to be in .PNG format. It doesn't allow any other format. Make sure that textures are in the .PNG format.
Modified Texures
We do not accept textures that have been altered from their original extracted form in anyway. Modifying the texture's dimensions, pixels, or format will result in the submission's rejection from the site.
Converting Normal Maps
Making Textures Load On Import
The Mesh
Does the model have unneeded parts, such as extra faces or vertices? Models should be optimized as possible.
Removing Doubles
Combined Sub-Mesh Issues
Rigging
While it is not necessary, submitting models with rigging is completely fine, and is encouraged when possible in order for models to be animated easier. The Models Resource only accepts rigged models in .dae, as it is a required base format. However, a .fbx file can be included if a .dae file is present in the submission.
Rigging Problems
Model Formats
Though you can include multiple formats, you need to at least have one model exported as .obj or .dae. Specific requirements for each format can be found below.
OBJ Specifics
Alongside the actual *.OBJ model file must exist a corresponding *.MTL file.
The MTL File
Material files allow it's corresponding Wavefront OBJ file to properly import and render textures into the 3D program you are using. There are a few steps that are necessary to make sure your MTL file works properly before you submit it up to the site.
MTL Paths
Connecting the MTL & OBJ File
Now that we have our OBJ + MTL file written, we need to somehow allow the OBJ file to interpret the data contained in the MTL file. This is done by adding the "material library reference" line into the OBJ file. An example of this is shown below:
DAE Specifics
Rendering Submission Icons
The (Small) Model Icon
The Small Icon needs to show a preview of what the model is/what it is about, by creating a render of the model.
The icon needs to be 148 by 125 pixels in size otherwise the submission page will give you an error upon trying to submit.
The (Big) Model Icon
The Big Icon needs to have a depiction of the model rendered in it's default pose. It needs also to be 750 by 650 pixels in size otherwise you will receive an error when trying to submit.
