 +===== Tree (Variant 2) =====
 +
 +| {{3d:low-poly-tree-variant-3.png?direct&340}} | Start with a **low poly cylinder** (6-8 sides).  |
 +| ::: | Scale vertically to full length of trunk. |
 +| ::: | Loop cut a few times and move around to give a bit of wobbliness. |
 +| ::: | Add a plane with two loop cuts. Scale loop cut outwards for a sort of leaf like aspect. |
 +| ::: | Bring center face up and rotate the inner cuts around to break flatness. |
 +| ::: | **''ALT'' + ''D''** to link duplicate and rotate around the Z 90°. |
 +| ::: | Repeat twice, each time in **Object** mode rotate a bit the branch to break evenness. |
 +| ::: | **''ALT'' + ''D''** to link duplicate upwards and rotate a bit around Z. |
 +| ::: | Repeat up to full height of tree and scale down as you go. |
 +
 +----
 +
 +===== Low Poly Crystals =====
 +
 +| {{3d:low-poly-crystals.png?direct&340}} | Make a shard : Default cube > scale Shift Z > loop cut twice vertically in both X and Y and bring middle vertex up.  |
 +| ::: | Bevel corners and merge vertices and add randomness. |
 +| ::: | Duplicate twice to create 3 different shards. |
 +| ::: | Create a cluster of shards by duplicating the lot and arranging them. |
 +| ::: | Join all objects together with union modifier (bool tool add-on to do on multiple shapes). |
 +| ::: | //If problem when joining either select another active object or just move/rotate slightly the active object that failed.// |
 +| ::: | At this point you might have a few massive N-gons to repair. |
 +| ::: | Edit mode > Select all vertices > Bisect tool to cut base (Clear inner + Fill ticked). |
 +| ::: | Rectify topology. |
 +| ::: | Add crystal material : transmission 1, roughness down. Add a base color. |
 +| ::: | Add a point light inside the Crystal. |
