Trim sheet 1
Trim sheet creation
“Trim sheets are textures which tile in the Horizontal (U) or Vertical (V) direction. They are used to quickly add detail to an asset with otherwise simple geometry as they generally consist of multiple trim elements which can be UV mapped onto an asset to add the illusion of a higher level of detail which is not present on the model.”
To create a trim sheet, first thing I need to do is to plan the section for each part in photoshop. Then I move the plane to Maya so I can create a base model for me to sculpt and bake later.
Then I import the low poly model in ZBrush to sculpt the high poly model. When it comes to the sculpting of stylized model, it is important to exaggerate the feature and keep it minimal. In this way the texture can have a nice, clean presentation.
After sculpting the model in ZBrush, I baked the high poly model on low poly model and textured it substance designer.
The Advantage of using trim sheets
The benefit of using trim sheets is that the artist only need to use one texture for a large collection of assets. In this way the artist can reduce the memory required to save and load texture.
“In general throughout a scene you will have multiple dozens of assets. Each of these assets will have their own texture sets, if we assume each asset has its own texture set that’s 3 textures for each asset in the scene on average. Clearly this would result in a lot of textures, as an example 12 assets would result in 36 textures, comparatively with a trim sheet you could potentially texture all of those assets with 3 textures.”
