As there seem still to be a lot of folks looking for a solution to this. I put a solution into [Camera facing foliage for trees via material - #12 by kaidawai](https://forums.unrealengine.com/t/camera-facing-foliage-for-trees-via-material/479427/12) The short answer is: - There is no “offset problem”. Offset is fine. wrongish guesses brought this up. - Pontius Karlsson does a **partial** Billbording by stretching the faces parallel to the camera. - Unity has meter units whereas Unreal has cm so stretching by 1 unit has way more impact in unity(factor 100). - early normalization destroyes the wanted form of a square and runs into division by zero. Pontius Karlsson did not do that and it breaks everything. - billboarding by streching means, the model needs to be crafted that streching gives the desired effect(smaller faces). - relationship between face size and uv/texture square size defines how much billboarding is done. you find a solution for 100% billbording using Pontius Karlssons approach with a working shader: [Camera facing foliage for trees via material - #12 by kaidawai](https://forums.unrealengine.com/t/camera-facing-foliage-for-trees-via-material/479427/12) --- _[View the full topic](https://forums.unrealengine.com/t/quadmesh-billboard-shader-not-working-with-instanced-foliage/210544)._
