Sprite's mask does not applied when render into RenderTexture

[GRaAL]

Hi,

I noticed that sprite masking does not work when the sprite is rendered into RenderTexture - here is jsfiddle which demonstrates it: https://jsfiddle.net/GRaAL/tt4bgppf/ (I'm using WebGL renderer).

I've tried to dive into Phaser code, but didn't found a reason. I see that the same DisplayObject._renderWebGL used in both cases - when rendered to screen or into framebuffer (RenderTexture) - and in both cases stencilManager is called with valid mask. Unfortunately I'm not so good in WebGL to understand what is wrong here.

I found an old issue in pixi itself about that (https://github.com/pixijs/pixi.js/issues/694), but I'm not sure which pixi's version is used in Phaser.

 

Could you please advice how can I make it work (and is it possible)?

Thanks.

In pixi (at least v3 v4) sprite masking works through a Filter, without Stencil.

UPD. its not alpha sprite mask, you actually use graphics for a mask, that's ok

Yeah, I saw it works in pixi. But Phaser uses its own modified version of pixi.

Is there a way to make it work in Phaser?
