+## Why does my Blender scene have a green tint or different color after building / deploying to Needle Cloud?
+
+This was a known bug in the Needle Engine Blender add-on versions **1.0.0 to 1.0.2**. It caused incorrect encoding of PMREM LODs during EXR compression, which gave some scenes a greenish tint. The issue only affected **certain EXR environment textures** (e.g. the built-in `forest.exr`) and only occurred in **Blender** — Unity was not impacted.
+
+**Fix:** Update the Needle Engine Blender add-on to **version 1.0.3 or newer**. The bug has been resolved and no further action is needed after updating.
+
+::: tip
+In general, regularly checking for updates to the Needle Engine add-on is good practice to benefit from bug fixes and new features.
