Interesting, I never realized that they didn´t actually move. I like how you looked up an example of a door that did and showed how that looked from different camera angles. Cool stuff!

There are still many hidden secrets left to discover!

I was recommended your channel by AngeTheGreat, and you've just earned yourself another subscriber :)

The lack of a depth buffer must have really been tough on PS1 developers. There's so many limitations and issues that arise because of it. It's funny to compare the world is not enough to goldeneye on the N64 because that DID have sliding doors.

[@Marcis.]

Yeah, but look how creative the solutions are! They really had to think outside the box.

[@JohnDoe-pk8lc]

hey where is mah refund. jk nice video

[@mr.m2675]

yeah before watching the video i was confused why it would be done like that but i realized that it would be an issue with the z order of the polygons like you said at the end of the video

[@mr.m2675]

are there any moving textures in 007? i can't think of any good reason either

[@JuraKudrik]

Thank you for these videos, really interesting, always eager for the next one!

[@laytonvicars4606]

Maybe because there was no sense in doing this? The textures in both examples are very different. In 007 it barely noticeable. In the Alien if they didn't compensate it the texture would look like in the example with the box.

[@Marcis.]

Yeah, not the best example but there are more sliding doors in the game and in most cases it's easier to see the distortion.

[@laytonvicars4606]

@@Marcis. anyway, great video. It's a neat trick I never thought about, even if I saw it probably a hundreds of times :D

[@lukabrasi001]

i think in MGS1, the sliding doors actually slide instead of scaling to the side

who else makes content like this, no one! 😎

[@irritablerodent]

I was immediately thinking; "Could you somehow counter-distort the texture to hide... oh... yeah, like that."

[@59spadesofalife52]

Im curious because I thought it was impossible how did you increase the FOV in resurrection?

[@eeanditto9156]

and he's BACK AT IT with the quality content!

[@swayybaby9772]

When do you think your game will come out?

[@Marcis.]

There is still a lot to do so I can't give a release date just yet.

[@ZanaGBYT]

no ZBuffer on PSX. So you really want to avoid flickering Z-Fighting doors.

[@phantomarchive]

So cool

[@samoliverdev]

How you got the wireframe effect on ps1 games?

[@Inkazor]

I love these videos. Plz keep them coming!

[@delick01]

I want my refund. LOL.

[@Marcis.]

muahahahaaaaa

[@vexedev]

So did they just offset the UVs to compensate for the scale in Aliens?

[@Marcis.]

That's my guess but who knows what kind of tricks they used!

[@Thelango99]

@@Marcis. Could be truncating the texture on one axis somehow.

[@wiktor3727]

it has its charm

[@CYON4D]

Nice one.

[@bogiesmigforl1]

How did they compensate for the scaling in Alien though?

[@Marcis.]

That's a good question! I can think of a couple of ways how to do it in Unreal Engine but back then? Who knows?

[@CyberWolf755]

@@Marcis. Can you scale the UVs (or whatever was the equivalent) on PS1 console?

[@Marcis.]

Definitely!

[@TheSuperQuail]

So they could have scaled the textures in relation to the scaling mesh?

[@AlFredo-sx2yy]

@@Marcis. well, considering this was back during the PS1 era, i guess they were still using some form of fixed pipeline so the way that it is possible to do it in unreal would not be exactly the same way they did it in the PS1. My best guess is that they would scale the door's geometry, and at the same time scale or displace the vertices' UV coordinates to make the texture look like it was actually moving along with the door instead of stretching. Im guessing that a way to do it would be to get all the vertices that are attached to the way and displace those, but that would work only if the door was 1 single poligon. Considering how the door in alien was made out of multiple polys, then the only idea i have left would be that they scale outwards relative to the edge that is being scaled down. That is, scale the door's geometry in one way and the UVs in the opposite way. The only problem i have with this idea is that im not sure it is the most performant solution so i dont know if this is really what they chose to do. I mean, i think it would be possible to do this operation in the PS1, but still, im full of doubts tbh lol.

[@pindeveloper]

It seems to me it would be easier to do if the doors open, they just move into textures, and do not change their scale, but to whom how🤔👍
