No transparent in Mobile Armory Render Patch

Hello

How to make Material and TileSheet transparent in Rendering: Forward Clustered (Armory Preferences: Legacy Shaders, Armory Render Patch -> Mobile), the background is black in TileSheet and Material is not transparent

I care about HTML5 compatibility and speed (IOS, Android, Desktop)

Armory Render Patch: Desktop works fine on PC but lags (is slow) on Android and doesn’t work on IOS (unless we enable Experimental: Enable Webgl 2 on Safari but no shadows and Armory Render Patch: Compositor doesn’t work)

Particle effects also only work on the Armory Render Patch: Desktop

best regards
