What is Trimflow?

Trimflow is a Blender add-on designed to add repeating patterns like ornaments, stitches, tattoos, or decorative borders to objects in a non-destructive way. 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 goal is to replace painting, stamping, or sculpting repeating details by a more efficient and convenient workflow. Instead of spending time on tedious and repetitive labor that is difficult to modify or improve once completed, Trimflow allows you to quickly iterate on your art and try out ideas without breaking things. Manual vertex manipulation or UV unwrapping is not required, and the topology of your mesh is pretty much irrelevant – this means that you can use it early during asset creation or even for prototyping.

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 greatly enhances the versatility of trims because they can now be a lot more than just homogeneous, monotone patterns that are cut off abruptly somewhere. Several trim sheets that support this feature are included in the add-on and a guide on how to create your own seamless textures with Head and Tail can be found in the documentation. Spoiler: it’s no rocket science.

On top of that, Trimflow can store the mapping information of trim sheets in JSON files, allowing you to quickly pick or swap patterns without fiddling with mapping settings each time.

GeometryNodes at heart | custom UI

Trimflow is based on GeometryNodes but comes with its own 3D view panel for setting up, adjusting, and managing the decals and their materials. This leaves the limitations of the Modifier panel far behind in terms of usability but still has the advantage that you won't lose any data if you were to disable or remove the add-on: as long as the node tree is still in the scene and you don't lose your textures, everything will stay in its place.

Add details quickly and try out ideas …

… bake trim decals into masks and use them later in your texturing workflow …

… or use them in your material for Eevee or Cycles renderings, keeping everything non-destructive 'til the end.

Detailed Documentation

Information on how things work can always be looked up in the online documentation. Every function and setting and how to use them is explained in detail.
