An M2 batch with two textures drew only its first stage, so Cupid's bow, the two Stratholme maces and the obsidian mining node lost their reflection. In 1.12.1 the element binds one stage per texture (`0x70b740`-`0x70b823`); a version 0x101 model takes each stage's combine from its header array (`0x70b7c2`, `[md+0x148][k]`), else from the blend table `0x811f8c`; a coordinate lookup above 2 generates the view-space reflection (`0x70b8bd`, the same map as stage 0's env path). These five are the only 0x101 models, each stage 1 preset 1, modulate on the default Direct3D device (`0x80a25c`).
benilla-m2 reads the combiners; the second stage is parsed, loaded and multiplied over the lit first stage before fog, with all six presets on D3D's ops.
Tests: the combine source, a synthetic two-texture parse, the obsidian node's stages off the install, the shader's coordinate and presets. Each fails without the change.
