Normally you use 3d software to create texture atlases for use in game engines. But what if you want to use texture atlases in 3d software?

For instance I have a texture atlas of leaves, containing half a dozen different leaves.

Is it simply a matter of creating your geometry, say a rough outline of a single leaf, and then adjusting your uv coordinates by trial and error until the texture aligns properly for this particular leaf?

Hi eco_bach,
Try out the “trace” node. It will create a geometry for you. After that a UV Project node with orthographic mapping. Getting the mapping right is a bit tricky if it is not a square image. You need to adjust the planar mapping to the same aspect ratio…
If i remember right the trace node comes with a good example scene.
