Hello, While applying multi materials to SPS system, picking returning null on non 0 material elements. Steps: 1. Create SPS with picking and multimaterial on. 2. Add 2 or more materials to SPS. 3 Use all materials to different particles 3. Try picking each particle. Only with material 0 will return value others will return null. Result: All should return valid particle values. [SPS MultiMaterials | Babylon.js Playground (babylonjs.com)](https://playground.babylonjs.com/#RCUHJA#57) Tested on version 4.2 and last nightly build. Please have a look at code, maybe I missed something. Thanks ---
