Technical notes

Soft Selection
What it does:

Soft Selection allows you to select and move/scale/rotate components (vertices, edges, or faces) this affects the surrounding geometry.
Instead of a hard, isolated selection, the influence “falls off” smoothly, so nearby components also move slightly.

Why it’s useful:
Great for making organic, natural adjustments (like shaping a face, terrain, or fabric).
Prevents hard, blocky objects that would happen if you only moved one vertex at a time.
Saves time, since you don’t need to manually tweak every vertex to get smooth transitions.

Sculpting Tools:

What they do:
Sculpting tools let you push, pull, smooth, grab, pinch, or flatten parts of your model, similar to digital clay.

They give more artistic control, allowing you to “sculpt” shapes instead of only using technical transforms.

Why they’re useful:
Ideal for organic modeling (characters, creatures, landscapes).
Quick way to rough in forms or add subtle surface details.
The tools often use a brush radius and falloff, letting you control the size and strength of your edits.

Why object scale matters:

If your object is too small in the scene compared to the default brush or falloff settings, the tools won’t work as expected.

For example: A

 Soft Selection falloff radius might end up covering the entire object instead of just a small part.

A Sculpt brush might feel either way too strong or barely effective.
3D software usually bases these tools on world scale (scene units), not just the object’s size.

In practice:
Always check that your model is properly scaled in the scene (e.g., a human should be around real-world human height in units).

This ensures brushes, falloff, and deformations behave as expected, and also avoids issues later with rigging, simulation, and exporting.

Summary:

Soft Selection smoothly deforms nearby geometry with falloff, while Sculpting Tools let you push/pull geometry like clay. They’re powerful for organic modeling and refining forms. But if your object is too small in the scene, these tools can behave incorrectly, so maintaining proper scene scale is important.
