Subject: Shader Meisters please help - water issues


kalon ( ) posted Mon, 06 November 2006 at 6:50 PM · edited Fri, 22 November 2024 at 6:05 PM

I've had this set for a while, but I can't create or find a material setting that makes it actually look like falling water. Does anyone know of a shader that emulates falling water?

Doesn't it come with a mat pose or P6 material gorup to apply the material?

 

Way too many people take way too many things way too seriously.


kalon ( ) posted Mon, 06 November 2006 at 7:35 PM

No, I think this product may pre-date Poser 5 / 6. There are no mat files as they are 3DS models. The only suggestion in the readme is:

 In Poser Version 4 or Poser Pro, for the water objects, reduce the appropriate Render Materials Highlights to about 50%, and increase the Transparency to about 85%.

I believe the ad copy was rendered in VUE

Maybe use some of the glass presets included with P5/6?

Or if you have other content that has a good glass/water material, save that out as a new material, and then apply it o the water.

I got these shaders through Content Paradise, but they were a set from Renderosity:

Easy!AS - Water, Glass, Mirror and Bubble Materials.

 

Can't seem to locate them here now, though.

I suspect Poser's problem with Water is the same as its' with Chrome, in comparison to Vue/Bryce.  In Vue/Bryce there really is a whole 3D world for a reflective object to interact with, but Poser does'nt have this luxury, it only has blank space, really.

Unless, you can figure out how this works(Please let me know if you can!)

Alternatively, you may want to look up bagginsbill over here, and tell him I said hi!

The skydome tut is a good idea.  If you use the glass material and the skydome you will probably be on the right track.

AntoniaTiger ( ) posted Tue, 07 November 2006 at 3:18 AM

Yes, a skydome will help, possibly improved with the texture fed to the Ambient Color input rather than the default Diffuse Color. Also, Reflection nodes, using the Spherical Reflection method. Both of these overlap with the Poser 6 IBL options. And you probably need raytracing and Refraction. What makes the difference, however achieved, is the water being rendered with light coming from all directions. And another useful trick is to add textures to the ordinary lights. I've an RDNA freebie that does that, with tree-branch patterns. It does make a difference to woodland scenes.

Everything show in the picture, including the water shaders, is included in my shader pack in free stuff.  You might like to give that a try.

I vouch for Ajax's set as well. If I recall, devised for Poser 5 but will work in Poser 6 .

That's right, infinity10 - built for P5, but most of them work fine in P6.

I'll have a free sky dome out in the next couple of weeks too.  It's being released with the updated free Dystopia city blocks.

Oh Boy, thanks Ajax! 

I'd love a Poser sky dome; could you put it in .PZ3/.PZZ format, please, then it would be scaled, positioned, lit, and camera friendly all from the get go!

Off to checkout the Materials...

Ajax,

I'll still be looking forward to your Sky Dome, but Bushi was kind enough to fulfill the request I sent him just before I first replied to this post.

I guess I hit it spot on thinking that Poser's actually needs an envirenoment to interact with, in order to produce Raytraced effects I've seen since Bryce 3 :tongue2:  The image on the left is what I've gotten going in the past couple hours I've had to play with my new BushiDome.PZ3 and Ajax's Moderate Water Material with UV.   The image on the right is the exact same scene after I only deleted the dome!

:woot:

Skydomes are great.  There are several places online that will let you download spherically mapped skys for your domes, but after a format of my hd I no longer have the links.

Hi Raven!  I have, it's a prop, but could'nt get the thing sized/positioned properly in relation to where the camera or lights were supposed to be.  I linked to a thread I started, a couple weeks ago, on Sky Domes, in my first post here, I linked us to it from there.  That failure, and this thread were why I asked Bushi, who'd relied to that other thread for his .PZ3.  I'm waiting to hear from Bushi again, I've asked him if he plans to put this in the Free Stuff, or what Term of Service he'd like; specifically if I can Redistribute.

And here it is again, with the skyline turned on.  They skyline is a sort of partial inner shell with a transparency map so you can put mountains or, in this case, a city on the horizon.

:tt1:  Wowy, that's awsome, Ajax!  I though you were kidding and had posted a Vue advertisement!

Have you decided if it will be available in .PZ3? 

Could you keep the Water plane in?

:tt2:


Ajax ( ) posted Wed, 08 November 2006 at 5:49 PM

It's all been finalised as of last week, so I can't make any changes now (not without destroying our release date plans and upsetting my partners anyway). 

It's a figure, loadable from the library.  The default scale and position should work fine and you don't need to worry about how lighting works with the sky because the sky doesn't respond to lights or cast shadows anyway.  The water plane is a body part that's hidden by default.  You just select it and turn the visibility back on to include it in the scene. 

The set comes with three sky textures (blue, cloudy and night), but only the one skyline texture and one water material.  I may release more textures etc for it at a later date, if I ever get around to it but if I do, the add-ons probably won't be free.

You can simulate a background in P6 by plugging an image into the "Background" of the reflection node. That way you will get the reflection of objects that are in the scene as well as a P4 style envoronment map.


kalon ( ) posted Wed, 08 November 2006 at 8:30 PM

Sorry about the delay in reply- computer issues. Ajax, I have you materials and love them, but I had always assumed some of the water ones (particularly falling water) were for P5 only, cuz I always end up with a cascade of black tar. I must be doing something wrong with the lighting. I'm trying for an indoor waterfall, what type of lighting should I be using.

Ajax ( ) posted Wed, 08 November 2006 at 8:35 PM

Sounds like you need to turn on raytracing in your render options.

If you've still got the zip with the materials in it, the readme has a checklist of things that could go wrong when rendering water and glass.  Also, it came with some pz3 files that have a whole scene set up exactly how you need it, so you could try opening one of those and seeing how that renders.

Thanks, I had just started the render with Raytrace on.  :blushing: It's a wonderful thing.

You know, one day I might actually figure some of this stuff out... then I'll be dangerous!

Ajax ( ) posted Wed, 08 November 2006 at 8:44 PM

...another thing that often causes blackness is if your water object still has shadow casting turned on.  Poser treats it like a solid object and no light passes through the water, so be sure to turn off shadow casting for any water or glass objects.

Ajax - Could you also include a camera preset, to match the Figure's default position?

Eric_3 - Where do you then plug the reflection node into?

Kalon - Make sure you have Raytrace Bounces set over 1 or 2.  I crank it over to 8, without noticing a differance in render time.

'fraid not.  As I said, it's too late to make any changes.  Anyway, you don't need it.  you can point the camera any direction and it won't matter.

I posted some examples on PoserPros a couple of years ago. Here's the link:

Note that the "Sphere map" is optional, I used it to make it less obvious what was being reflected.

I can't wait for your skydome btw :) It looks awesome.

Meddling with water myself atm, using the "Medieval Garden" (was a freebie at Daz) which is driving me potty, to say the least.
So much so... I'm doing it in Carrara now. :)

Yeah, it's at DAZ in either of the free Dystopia City Block packages (or any of the non-free ones as well for that matter).

Dear Ajax,

Thank you!  Wow, this Sky Dome is fantastic; it loads with it's Ground in place, the scale is fine, and there are plenty of interesting material zones.  It must work wonderful with your free materials!

I have one critical question; how did you know to distort the sky map(my pink highlights), what is that known as?  I've read a lot of, and DL'd for, Spherical Mapping Correction; but none of that does this, nor work as well!  I'd thought it was a Photoshop Distort Filter, but Polar Coordinates was my best guess.

I ca'nt wait to start shuffling the blocks around.

Sincerely,

Angelouscuitry~

Ajax ( ) posted Sun, 25 March 2007 at 4:33 PM

Glad you like it :-)

The skies were created procedurally in Vue and then exported on a UV sphere.  I can't think of any other way you could create a texture with the right mapping, but for anybody with Vue it's a very easy way to make new sky textures.  

I plan on releasing a pack of alternative sky textures in the next couple of months.  It will probably be a commercial package, but cheap.

Angelouscuitry ( ) posted Sun, 25 March 2007 at 5:14 PM

Wow, thank you very much for your reply, I had no idea Vue could do that, which version are you using?

This may well be a question for the Vue forum; but what were the steps you used to export your current sky, as a map, like this?

Again, congradulations, this contribution to the Poser community is incredible!  Poser Reflections and Water just would'nt be half a interesting without your help!  Can you plan to add this to the Renderosity Free Stuff, I think it'd be the one and only Poser Sky Dome there, and that many people would be very plesantly surpried to even know it even exists!


Angelouscuitry ( ) posted Sun, 25 March 2007 at 5:46 PM

P.S. - Were the Skyline and Water areas of AxSky_Blue.jpg, a part of the Vue export,or did you composite those on?


Ajax ( ) posted Sun, 25 March 2007 at 7:45 PM

I used Vue 5 Infinite.  I'm not sure which other versions can do the job.

Once you have your sky ready, you go to the File menu and click on "Export Sky", then for "Supporting Geometry" you choose "UV Sphere".

The skyline part of AxSky_Blue.jpg was composited on from a panoramic render (also done in Vue - use "panoramic view" in the render options).  Vue renders an alpha map at the same time.  I used that to make the transparency map for the skyline.  

What looks like the water area on AxSky_Blue.jpg is actually just dead space.  It's created automatically by the sky export process, but not used on the skydome.
