Smooth the displacement map.....

[victorwol]

Hi! I hope is possible, how can I smooth the displacement map used? I need to get very calm waves, which the ocean texture some how gives me is I lower the details, but then I see squares on the rendered surface, and also, the waves texture from MAX gives me a better result for what I want, but look at what I get?



even the ocean texture could be useful if there was a way to smooth the result.

Thanks!

never seen before such steps, we will try to reproduce it from scratch, in case of no success i will ask for the scene.

[Ivaylo Katev]

i was unable to reproduce the square issue with the ocean texture, but the max wave texture steps appeared, the reason is that the texture itself is very old, perhaps from the very first versions of the max, and is only 256 levels of gray.

[Ivaylo Katev]

well, the square issue appeared, hopefully will be fixed until the end of the day

the problem is resolved, download the tomorrows nightly and set the ocean subdivisions to zero.
the problem is related to the subdivision of the mesh, that is made in order to have fine details from the displacement. if the displacement has no fine details, the square issue appears. setting the subdivisions to zero signals to not subdivide, this is not possible in the build you have, there mesh is always subdivided by design

[victorwol]

thanks! but if I do not subdivide then I will get all really hard edges particles, I was using subdivide setting around 50 to get a nice rounded shape look of the water spalshes without having to go super high in the resolution of the grid. ( I might be wrong since I'm not in front of the program right now)

Now, there is a mode, can't remember the name now, that creates really nice rounded geometries for the particles, but can't be used with ocean, that would be really cool.

[victorwol]

is it OK to discuss problems of the betas here? I don't see a special forum for it.

[victorwol]

Another problem that I see and have no clue how to fix is that I get borders on the edge of the screen when waves or ocean even goes up a bit, like the plane created needs to extend a bit more, makes sense?

you mean the cap mode? now when you put subdivision to 0 it becomes exactly like it. i think you mistakes it with the mesh smoothing. it's a different setting. if you set the subdivisions to 50 the rendering will never end

You are probably right, I was talking about mesh smoothing. In which tab is that subdivision you talk about? Thanks!

I can only find Skyline subdivisions, and that was there before, so is that the subdivision you are talking about? The documentation says that affects the areas far from the camera only....

Thanks!

[Ivaylo Katev]

yes, i'm talking about the skyline subdivisions. the name is a bit out of dated, because it was introduced to subdivide the mesh in the skyline area, as described in the help. however some users complained that the simulator has less details compared to the ocean extension and it's visible as blurred rectangle, with no fine details. this happens when the simulator has low resolution and simulator mesh has triangles bigger than one pixel. so, we applied the subdivision over the entire mesh, every triangle bigger than certain size is split in two or more triangles, and this resolved the problem. we will change the name of the parameter, it's a bit misleading.

[victorwol]

I see, I changed that to zero and the render was horrendous. The ocean close to the skyline was just a blurred thing. And didn't noticed any improvement on the close part.

Could you check on the bug of the ever lasting dripping thing with wetting ON?

[Ivaylo Katev]

with the new nightly build? what is the name of the parameter. it must be changed now.

[victorwol]

this is what I get when I set the Skyline subdivision to zero with the latest version I installed, yesterday, after you told me from 3/26



it is revision 25662

but whatever number I put in there, the only difference I see is on the back of the ocean, the stepping on the front or mesh on the front seems to not be affected at all by this parameter.

And even with the wetting off, I still have particles staying adhered to the logo after comes out of the water and stay there forever attached to the object.

what are the chances to get the ever lasting emitting of wetting fixed in lets say, next few days? This job is for an internal thing, so I do not have that much of a pressure like if I had a client waiting, but I have already requested authorization to return the software, which I would love to not have to, your company gave me two weeks to make the final decision.

I think if I can get the wetting working and not emitting stuff forever, they I should be able to achieve the look I'm looking for.
