if 7 years ago there was a single example of paralllax with self-shadowing, so it's not fair to blame Ondra on his statement.
I apologize if I seemed rude, I did not want to blame Ondra for anything) maybe it seems because of my bad English. I just wanted to say that this is an important and necessary feature and we would be very happy to get it in our arsenal)
I already wrote in another topic about the connection of decals and parallax, we can not use decals with a negative height without using parallax bump and self-shadowing , and most decals are such, I mean cracks, holes, potholes.
Please relax Romullus, a discussion of these things and a direct connection with the developers - this is why this forum exists)
all the best to you and Ondra)
