The most impressive use of water in rdr2, for me, is after it rains there's still water dripping from shop awnings and gutters. The level of detail in small bodies of water help sell the immersion. Details you don't really notice because of how brilliantly mundane they are.

@xXYourShadowDaniXx 2 года назад

Whats really cool about raytracing is, once it becomes possible for every video card to at least do 30fps, all the effort into faking lighting can go away but you can put all that into stylizing and other parts of the game to improve quality. Things will only get better when tech can simulate in realtime.

@mettaursp309 2 года назад

That's the part that people don't get when they dismiss it as a gimmick: it greatly improves workflows for designers & artists, and enables use of environments that were previously impossible or would be guaranteed to look like garbage with faked techniques. The gap in visual quality will also only grow as time goes on and real time ray traced techniques mature, leaving raster rendering in the dust.

@choccymilkyt Год назад

@@mettaursp309 yes it's a good thing and improves the quality of games, but right now barely any video cards can run it smoothly on all games so right now, very realistic shaders still have to be created to be able to get the same feel on a pc or console that can't handle rtx. that's why it's considered a gimmick, it's not changing anything at the moment but making it more mainstream will change things

@nightmare4eVerr1 Год назад

Moores law is dead. Goodluck getting raytracing to work. Raytracing currently still only simulated very few bounces compared to real light that bounces continously. So that future where raytracing is not a gimmick is 10-20 years away

I think it also should be mentioned how the post processing effects can be used here. When the player goes under the water a blueish tint is added to the color grading. A very simple and very powerful effect.

@ashtongiertz8728 Год назад

7:00 I mean, for optimisation the most obvious solution would be to have distant water only use the normal map, using an intensity slider for the vertex displacement shader to provide a gradient between the high-res and low-res water. To minimize calculations, you can have the VDI slider use a coordinate grid instead of going on a vertex-by-vertex basis.

@venomtailOG 2 года назад

Vertex displacement is a pretty simple concept, what I struggle to understand is how exactly developers match up vertex displacement with physics of the player character and any other things they might be in, such as a ship. It'd be very heavy to check every single vertex induvidually, update the physics position of there a collision of water is so that clearly can't be it. Would love to get to the bottom of this intruguing achievement.

@surfgame 2 года назад

It is super heavy. I use unity and the collider on a mesh to interact with the surfer in Search For Surf. I have to be very minimal about vertex count and other cosmetics. Basically get it working and then minimize until performance is good.

@vibaj16 11 месяцев назад

I doubt it affects the physics much at all. It's probably still treated as a flat plane. Only small scale very noticeable things like gunshots would have to take the vertex displacement into account

And the different kinds of water look great; murky water, calm lake water, stream to rivers, and of coarse the ocean waves. And it's all adjusted according to the weather at the time.

@Sweenus987 2 года назад

A lot of games don't use vertex displacement for disturbances caused by players, objects, impacts etc. Where it's not obviously vertex displacement, they use a normal map that has a wave that propagates and then layer that on top of the original (or something similar, I haven't implemented such a thing myself yet). And a note, underwater foliage moving works essentially the same as foliage on land implementation wise. For anyone interested in more information regarding implementation beyond simple normal textures, I would recommend looking up Gerstner Waves.
