Background Image Reveal on Hover Effect

Hello, can someone explain to me step by step for newbies.
How did you do the effect that the bricksforge home has?
I would like to do the same with an image or a video, the YouTube tutorial is more than 1 year old and it is not the same effect (I think).

Thanks for reading and your help.

Regards ,
Adolfo.

Jeffrey created a video about this:

Hello, thank you for replying.

Yes I have seen Jeffrey’s video, in fact I found it easy to perform, but, he is not using bricksforge.

Since you give that example: how can I implement it with bricksforge?

I followed this tutorial: https://www.youtube.com/watch?v=0ixqha4p_5c

Even though it is 1 year old, I found it amazing and it worked for me.

Starting from that tutorial, is it possible to create that effect with the JS that Jeffrey offers in bricksforge, how can I do it, or bricksforge doesn’t solve this kind of effects?

Thank you.
