If you’re concerned about backdoors, just look at the asset. Posting unfounded speculations is harmful and is a critique on OPs credibility that isn’t founded on anything substantial in terms of the assets or the code within them.
@ OP - there are scripts in the asset, so right now the title is misleading. The code is just for visual effects (see below for anyone interested), but given the explicit title of the pack “(No Scripts)”, this may be justifiable concerning to someone who doesn’t know what they are looking at.
