Q: My item just got rejected. Why?
A: Chances are that it didn't meet one, or several, or possibly all of the guidelines listed below:
Obscenity: We will automatically reject any obscene items. (Don't even bother.)
Copyright infringement: Even if you made the model yourself, if you used an existing likeness, it’s copyright infringement. We can't and won't put other people's intellectual property in our game, for the simple reason that we don't own it. They do. We will automatically reject any items based on existing intellectual property.
Overall Tone: We may reject an item if we feel it deviates too far from the tone of TF, either by being too cartoony or too photorealistic.
Gameplay: TF's characters have distinctive silhouettes that help a player differentiate between classes in the heat of battle. Consequently, we tend to avoid items that overtly obscure or confuse these silhouettes.
Noisy Details: We tend to reject items that utilize a lot of fine surface details (scales, skin pores, fabric textures, super-detailed normals, etc.). We prefer items that utilize flat colors that are close to the TF color family used by the base game. Items that are fully black, fully white, or fully saturated tend to read poorly and clash with the game environment. Most TF items use a subtle vertical gradient with a subtle ambient occlusion layer multiplied over the top of the colors.
Technical limitations: Items that require changes in character clothing or facial animation might be considered too costly to produce. Note: This does not mean that we will always refuse an item based on technical complexity. But nine times out of ten, it probably isn't helping your case.
