the problem is once i set opacity to 0.5 for eg, im getting my stl meshes being rendered in the center of the container and not in the specific viewport for meshes !!
there is no errors being raised in the console, just the rendering being out of the viewport boundaries, and i’ve just test it on brave browser.
i got some answers online said that each actor with opacity under 1.0 will be ignored or something like that.
