Splash particles are WIP

More technical info:

• Vertices are extremely sparse far away, but detailed up close.
• Vertices render in different FPS's to increase performance (farthest out is 4 fps)
• Ocean center moves with you while preserving features

[torn scroll]

what do you use for the ocean?

editablemesh? wedges? bones?

[pale bison]

editable mesh, otherwise I wouldn’t be able to use LOD

[torn scroll]

how do you get around the memory limits

[pale bison]

you mean the 2048 size limit?

[torn scroll]

no

the memory limit

on editablemeshes

for clients

it limits the amount of editablemeshes you can have

[pale bison]

Haven’t had to

Just reached 2048 limit

the beauty of sparsity

[torn scroll]

whats the 2048 limit ??

[pale bison]

Part size limit

its the same for vertices

[torn scroll]

your editablemeshes are that low res?

whyd you need 2048

[pale bison]

2048 studs across

[pale bison]

high quality in the middle, low quality outside. LOD

[torn scroll]

id imagine youd use more than 1

editablemesh

[pale bison]

its a detail gradient

[torn scroll]

for this

because of the tri limit

[pale bison]

right now no

[pale bison]

nope not reached it

[torn scroll]

well how did you solve this 2048 issue

[pale bison]

i havent yet

[torn scroll]

incredibl

[pale bison]

i will just add more meshes though

and no problem

[torn scroll]

hows performance looking with it

[pale bison]

move one around in the direction of the camera

[pale bison]

my school laptop hasnt stuttered at all

which is pretty impressive

[torn scroll]

what do you use for the waves?

like

to generate them

mathematically

[pale bison]

i modified a gerstner function

to tile less

tiling looks quite bad

[pale bison]

but its multiple waves stacked on each other

[torn scroll]

and how did you do that

easier said then done

from my knowledge wave tiling is a long lasting issue

for all sorts of games

[pale bison]

I’m tempted to keep it a trade secret but I could tell you

[torn scroll]

ok do it

[pale bison]

i follow the line and rotate direction back and forth by a sine wave, but its slightly dominant in one axis

[torn scroll]

follow what line

[pale bison]

the wave line

[torn scroll]

oh

[pale bison]

perpendicular to direction

[torn scroll]

ok ty

[pale bison]

you gonna steal it now

[vale pecan]

gta 5 water physics feels like good job

[pale bison]

Added occlusion which improves performance by ~2.9x @torn scroll

I also made the movement look more realistic

[torn scroll]

how are you adding occulsion culling

[pale bison]

Since the water is centered around the camera, I can literally just do a comparison check with grid position instead and knock off an entire row.

[torn scroll]

what do you mean by this

[pale bison]

Oh I just set the vertices to below their current position at like 1 fps

but the performance heavy part is the stacked gerstner wave calculations

[pale bison]

[daring wind]

whats your fps in this video

im not sure if its the one lagging or the ocean

[pale bison]

its taken from gyazo so take it’s fps with a grain of salt

i’ll record a video with a fps counter up

[pale bison]

I def need to add multithreading due to the set position

90% of the runtime is taken up by it

[daring wind]

ouch

[pale bison]

and of course roblox didn't add my suggestion to add bulkmoveto for vertices
