Issue with transparency not functioning in Aframe a-entity template thumb data

When I switch to virtual mode, I am encountering an issue where a .png rounded corner image with the entity template as data thumbnail is displaying with a black square box instead (refer to the screenshot for better clarification).

<img id="subway" crossorigin="anonymous" src="images/new/subway.png">
<a-entity id="links" layout="type: line; margin: 2.5" position="-5 4.6 -4">
      <a-entity template="src: #link" data-src="#expense-subway" opacity="0.5" transparent="true" rotation="0 30 0" data-thumb="#subway" class="links"></a-entity>
</a-entity>

Answer №1

If you want certain areas of an image to be fully opaque and others to be completely transparent, without any in-between transparency levels (1%-99%), then it is best to keep the default opacity/transparency values (

opacity: 1.0; transparent: false;
) on the material component. This mode is known as "mask" or "cutout". Next, you can adjust the alphaTest value to set a threshold for which parts of the image remain hidden. The specific value may need some tweaking depending on the image, but setting alphaTest: 0.25 seems like a reasonable choice in this situation.
