Hi Forum,

As you can see, I am mapping multiple videos with a alpha mask using jit.gl.videoplane. In my background video (sub-patch video_bg) on opening up the patch, i have to change the @blend_enable 1 to something like 0 and then set it back to 1, then then re-position the video to get the alpha mask to work correctly. This is totally annoying and something is not right. Any suggestions?

It might be a layering issue. If you’re not using @layer to specify drawing order, it could cause problems. If every videoplane has the same @layer, then their draw order will be indeterminate.
