Trimflow: Non-destructive trim decals with curves

3 ratings

Trimflow is a Blender (3.5.x+, 4.0) add-on designed to add repeating patterns like ornaments or stitches to objects in a non-destructive way. It is very similar in approach to Substance Painter's Path tool, but utilizes trims instead of brushes.

By simply drawing a curve onto the surface of a mesh, it turns your trim textures into decals that can easily be adjusted, copied, or swapped for another. The integrated baking tool then turns trim decals into masks. These masks can then be used for material creation, either in Blender or in other applications such as Substance 3D or Marmoset Toolbag.

Or, with a little bit of shader magic, decals can also be blended with their target object's material. This is useful for rendering inside Blender without baking, keeping everything completely non-destructive.

Trims on steroids

Trimflow is able to utilize trims that have Head and Tail pieces at their ends with the seamless, tiling part in between. This optional feature greatly enhances the versatility of trims because they are not just cut off suddenly somewhere anymore. Several trim sheets are included and a guide on how to create your own patterns with Head and Tail can be found in the documentation. Conventional trims from your existing library or 3rd party asset packs can be used as well of course, or even adjusted to support the Head and Tail feature.

What's in the box?

Included with the add-on are the Sami Knife (incl. comments in the shader view) and the Shoe examples that are shown here with the used trim sheets and textures. Information on how things work can always be looked up in the online documentation.
