Olive oil material

Posted in: Maya
Hello everyone,
I’m trying to create an olive oil material for an liquid simulation that I’m doing.
I’m looking for something like this:

I’ve started with an dielectric material for the first tests and with an phong shader where I set the diffuse level to 0, reflectivity and transparency to 1…
But at the moments the results are simply a crap.
Can someone give me a tip where to start.
I would really appreciate.
Thanks

creating a f 18 fighter jet trail.

Posted in: Maya
hey everyone,

I haven’t played with maya dynamics much, and I was wondering if anyone could point me in the right direction to get a look like this.

i pretty much want it be a constant burst, since every shot with a aircraft will be in flight. Any ideas or tutorials you know of will help. thanks!

*i think my main question is how to keep a dynamic particle effect repeating or at least constant.

Syntheyes to maya help (and other questions)

Posted in: Maya
Alright first of all im going to post all the questions i ask here for problems i may come across to save forum space, But heres my question right now

I import the track data from syntheyes into maya 2009 and its tracked good the image sequence automatically appears, but the grid isnt on the ground.. (which is of course normal) so i move the camera to make the grid match the ground, but when i move to the next frame the grid just goes right back to its original spot.. What do i do? i dont want to manually move the camera in the same spot for every frame..

Edit: Quick thing is there a way to move the camera around without just rotating it around? Like when you alt+click it rotates it around, what do i press and click to move around on xyz and not rotate?

Stereoscopic 3d problem

Posted in: Maya
Hello

I am attempting to do a stereoscopic animation and if you will look at the attached you can see the problem. I have lowered the interaxial separation down to 0.150 and you can still see problem and the belt buckle on her back. Please advise how to balance such projects and thank you very much.

Expression Issue

Posted in: Maya
I put this bit of code together and I’m stuck as to how I can integrate the simple expression below into one that uses the string names of the lights. As you see it’s just a basic formula telling the rim light to be the key * 2/3.

——-UPDATE——–

Nevermind. I figured it out!

Code:

global proc js_lightSetup ()
{
        spotLight;
 rename "keyLight";
 string $keyLight;
 string $kl[]= `ls-sl`;

        for ($key in $kl)
          {
                setAttr ($key+".scaleX") 6.0;
                setAttr ($key+".scaleY") 6.0;
                setAttr ($key+".scaleZ") 6.0;
          setAttr ($keyLight+".intensity") 1.0;
         
    move -r -ls -wd -42.0 102.7 86.0;
 rotate -r -os -46.0 -26.0 0;           
 xform -ws -rp 0 0 0 -sp 0 0 0; 
  }
 select -r $kl; 
 int $size= size ($kl);
   
//create fill light             
             
 spotLight;
 rename "fillLight";
 string $fillLight;
        string $fl[] = `ls -sl`;

        for ($fill in $fl)
          {
                setAttr ($fill+".scaleX") 6.0;
                setAttr ($fill+".scaleY") 6.0;
                setAttr ($fill+".scaleZ") 6.0;
 setAttr ($fillLight+".intensity") .5;

  move -r -ls -wd 37.6 80.6 102.0;
 rotate -r -os -31.0 25.0 10.0;               
 xform -ws -rp 0 0 0 -sp 0 0 0; 
  }             

 select -r $fl;
 int $size= size ($fl);
   
//create rim light
           
 spotLight;
 rename "rimLight";
 string $rimLight;
        string $rl[] = `ls -sl`;

        for ($rim in $rl)
          {
                setAttr ($rim+".scaleX") 6.0;
                setAttr ($rim+".scaleY") 6.0;
                setAttr ($rim+".scaleZ") 6.0;

              // expression -s "rimLightShape.intensity=rimLightShape.intensity= keylightShape.intensity * 2/3;";
  // expression -s "$rl.intensity=$rl.intensity= $kl.intensity * 2/3;"

 move -r -ls -wd 0 76.5 -104.0;
 rotate -r -os -142.0 -1.0 0; 
                xform -ws -rp 0 0 0 -sp 0 0 0; 
      }

 select -r $rl;
 int $size= size ($rl);
}

Smoke Fluids and Live action

Posted in: Maya
Hi guys I was wondering if I can get some advice. I have someone on gs and I was want smoke to go around him while he walks. What I am think of is building a fluid container to make my smoke. I would use a cylinder for his legs as proxy geometry, and animate to the way the person walks, then hide the primary visibility when it comes times to render. Do you think will give me a good result ?

Batch Render problem

Posted in: Maya
Hi, I was wondering if there should be any differences between just a standard single frame rendered image in maya and a batch rendered image.

Basically I have been having trouble rendering shadows off of maya fluids, in this instance fire. If I render a single frame from the maya viewport I can see the shadows are all present and correct, but as soon as I go to batch render it the shadows disappear. A secondary difference is the glow on the flames is much stronger on the batch rendered version.

As far as I know the render setup is sync’d to both ways of rendering and therefore should emmit the same result. Am I doing something wrong?

Getting Cam local z rotation around look-at/axis?

Posted in: Maya
Hey All…

I was lucky enough to have been given an animated camera that has a ‘look-at’ point and an ‘up’. I am going to fake some particles that hover and move past the front of the camera, but I don’t want to try and emit and parent them to this moving camera. I am hoping, instead, that I can calculate the camera’s rotation around the axis that would be defined by the look-at point and the camera axis, and then pipe that over to a static camera’s rotateZ, resulting in a camera that I can use to render my particles (they just emit and move past this static camera)

Is this possible? If I just knew some more vector math and such, I think I could figure it out, but perhaps someone here can help me along the path?

Thanks!
Ryan
