Both units are the 40250 bodies; only the PDT-stream draw becomes UIRenderAddImage (with the rendering mode). SCREEN/COLOR_DODGE were packed as 0x28 (INVDESTALPHA+ONE); 40250 uses INVDESTCOLOR+ONE (0x2A). OnIsType calls the base OnIsType instead of 40250's recursing IsType. port.grp_resource covers the quads, UVs, colour and blend mode. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
