Is there a bug in the new engine version? How can I change the color of the text?

How can I change the color of the text?
In the previous version of P.C. I can set the material.blendType = pc.BLEND_ADDITIVE, and change the color of the text normally. but in current version, just only can set the material.blendType =pc.BLEND_NORMAL, otherwise the text will not show.


    this.entity.render.material = this.entity.render.material.clone();


    var material = this.entity.render.material;

    material.emissiveMap = this.texture;
    material.opacityMap = this.texture;
    material.blendType = pc.BLEND_NORMAL;
    // material.blendType = pc.BLEND_ADDITIVE;

    material.update();
