Ocean submarine test

[flachdrache]

owww bummer - tiles might match but its seams like the wave calculation is not tilable but iam no expert either ... you might can interpolate vertex.y like in the curve function ?!

 

You can use a simple linepick from above to below waterpatch to place stuff at the intersecting point - however, sice the sender knows nothing about the receiver and the receiver usually doesnt care about any stuff the sender might tries to archive the user in question might have to come up with its own kind of filter to get rid of failures forwarded into space by the sender.

 

Ps :

there was a (very) early preview of sea waves [in] le3d which appearance a little more realistic, however afaik

[Guest Red Ocktober]

i managed to get a 3x3 tiled surface to line up perfectly without to much trouble in my cpu based waves...

i'm gonna try basically the same approach with this...

 

Shad... those screenshots look better and better with each iteration...

Hmm... well xz and y displacement with 12 aggregated waves, makes not perfectly tilable.

If you still want it I can upload it in it's current state. I tried with some skirts but you can still notice.

But I guess an adaptive mesh would maybe solve this, but that's beyond my programming skills.

Max mesh size are 32k triangles, I get all sorts of distortion if I go any higher.

[Guest Red Ocktober]

the current state of your work is excellent... i'm ready to apply it...

[Pixel Perfect]

I'd love to try this too, thanks again for all your work on this.

[Benton]

Oh wow, this water looks amazing. How does it look close-up?

[shadmar]

Ok it's in the store now, let me know if it works

[ChrisV]

Ok it's in the store now, let me know if it works

Checking it out now.

Thanks a lot, man! Nice work!

 

Cheers

One more thing, the mesh has skirts, but the skirt normals points straight up to minimize tiling visibility.

 

And... forgot to change the deafults

For best look with deafult skybox, set cubemap blend to 0.35 and bump to 0.3 and normal to 0.5 - fixed and reuploaded.

 

Should look like this then:

 

[ChrisV]

Hum...for some reason, I can't get it to work.

I did as mentioned, copied the shaders in the 'mesh' folder of the shaders.pak, and put the 'ocean' folder in the 'Models' folder. I can see and put the ocean patch in the editor, but I only see a transparent red plane. I've matched the skybox material of the atmosphere to the one in the ocean material, but no changes. Also, when I click the checkbox 'Active' in the 'General' settings of the ocean and click apply, the name of the ocean patch dissappears. Very weird.

 

EDIT: clicking apply makes the ocean (red plane) dissappear, and also the name.

 

Any ideas/suggestions? Thanks.

[shadmar]

Any output in the Editor.log worth mentioning ?

 

Edit : ah waternoisedot3.dds not in the zip, hold on 2 sec..

Edit2 : Re uploaded the zip and added the missing texture.

 

Try now.

[Guest Red Ocktober]

works fine here (2.50) with one or two small things...

 

name property and y position won't persist after i close properties dialogue...

 

also, checkbox for active remains unchecked...

 

otherwise, ocean looks great...

 

still looking...

 

oh yeah... almost forgot in my haste BIG THANKS for this...

 

more...

x and z positions work...

second test neither x,y,z position properties persist...

 

what's the dimensions of the mesh?

 

 

--Mike

[shadmar]

Aye sorry, wrong version of the lua script (GetKey else missing) Fixed and reuploaded.

The mesh is by 512, but you should tile on 504 due to the skirts.

[Benton]

Can you change the transparency of the water? I can't try it out till Monday cause of a lack of computers, and I was just wondering. I was playing Uncharted 3 and there is this map where it is a couple shipwrecks in water and you can swim around, and you can see about 10 feet into the water before it gets cloudy. Is this possible with shaders? Josh's waterplane got transparent when you set the softness at the right amount and looked down at it, that effect was very well done and I am wondering if maybe you reused some of his code? So you could see some fish in the water close to the surface, but not very deep. It would add that last bit of realism. So I guess my question is: Can you make it transparent, and if so how advanced is that transparency? And what does it look like underwater?

[shadmar]

Not in the current version, maybe in a later version, its just an wavy mesh for now, no underwater or transparency. Haven't figured out how transpericy in the shaders works (refraction) I seem to get reflection or some distortion. Ah well learing from the existing shadersis hard

[shadmar]

Another small update, fixed the y pos bug and added sliders for specular and gloss in the shaders + updated mat file.

[Guest Red Ocktober]

updates working in 2.5 and 2.43...

 

--Mike

[Benton]

Maybe you could use the waterplane shaders for underwater?
