General

Q: Can I paint multiple objects at once?

Yes, select all objects before applying; most operators loop over all selected meshes

Q: Will reloading the addon lose my painted data?

No, vertex color data lives on the mesh, not the addon

Q: Live Editing is slow on my mesh

Turn it off and use Apply manually; high-poly meshes are expensive to re-evaluate on every slider drag

Q: Is there a hard mesh size or polygon limit?

No, there is no hard built-in limit. The practical limit is set by the user’s hardware, so very large meshes can still work, but performance will vary depending on the computer. The add-on has been confirmed to work with models ranging from a plane mesh to 8 million polygons.

Setup

Q: What layer name should I use?

Whatever you'd like, by default its set to FoliageVertexPaint.


Painting

Q: Why did my other channels go black when I painted?

You filled ALL channels. Use the channel lock or Override only the one you need

Q: I painted Red but the viewport looks wrong

Switch preview to R channel using the channel buttons, or hit Flat/See Vertex Color first

Q: My gradient looks blocky/jagged

Increase Smooth Iters, or lower Falloff

Q: Stem→Leaf painted the wrong direction

Toggle Reverse, or re-select the base/root verts before applying


Per-Plant tools

Q: Select Nearby isn't grouping my leaves with the stem

Enable Detect Overlap, or increase Group Distance slightly

Q: Apply Random gives the same value each time for Green

It doesn't; it re-seeds from system time every click. If values look similar, widen Min/Max range

Q: Blue channel keeps giving similar colors

The 35% contrast gap logic helps but works best with a wide Min/Max range (e.g. 0–1)


Cutout

Q: Even Triangles looks wrong, What now?

Try the following in the advanced settings.

  • Contour Tolerance: lower values keep the traced silhouette tighter and often fix unstable edge shapes.

  • Gap Closing Radius: increase it when tiny slits or breaks should merge; leave it at 0 to use the preset default instead of forcing a tiny manual override.

  • Quality Preset: move from Medium to High when thin features need a cleaner contour before re-triangulation.

Make sure to always cut again after changing the advanced values, this is important, after that re-try Apply Even Triangles

First undo the Even Triangles and the cutout. Adjust the advanced settings, then click Generate Cutout and Apply Even Triangles to generate the new result.
