Description
Posting bug report as instructed from PlayCanvas forum: https://forum.playcanvas.com/t/light-shadow-bug/25343
Use of lights with "Cast Shadow" checked, and using PCF 3x3 shadow map breaks rendering of dynamically generated meshes in Windows/Android +(Firefox). Works fine on iOS (iPad Air).
Test project URL: https://playcanvas.com/editor/project/916295
Steps to Reproduce
- Check if both lights have "Cast Shadow" checkbox checked and one uses PCF 3x3 and other one has PCF 5x5.
- When 5x5 is used, mesh is visible as expected, when 3x3 is used, texture alpha is respected but color is black.
- Lightsources can be toggled by clicking the "Switch lightsource" option and console logs active lightsource.
