from solid state to fluid

hey guys,

so far i have only modelling and a little bit of animation eyperience in maya and for the next project i’m trying to clash a stone to a wall and in the moment of the impact it should transform to a fluid and colorize the wall in the original colour of the stone.

under which subject or topic can i find some tutorials, what is the right definition of this type of animation? fluids? deformation?

thanks in advance!

UV snapshots and Texture Painting?

Hi

I want to know do most people UV a low resolution mesh before using smoothed on a mesh? I know there is a check box in the options for mesh smooth with Smooth UV, do you keep this box checked at all times?

I also want to know if you take a UV snapshot of a non smoothed or a smoothed mesh for texture painting?

I really hope someone can answer my questions thank you.

Expressions help..

hi.. i have a question to ask ,,
so i wanna to switch between two diffrent projecting cams by using either expressions or condition node in the hypershade .. for example when the render cam reaches 90 degrees in rotation it will use the camA projection and if it exceeds the 90 degrees it switches to camB and its projection with fade..
thanks in advance

Camera Projection Question ..

hello everyone i am new here 🙂 and i have a question about something in my mind in the camera projection technique ..

i know that when i do such a project with camera projection i should have one camera to project from and another to animate and render with .. so here is the question .. could i project multiple projections with multiple projection cameras to the same object that i created for the projection ?? and what is its problems that occurs by doing that ??
thanks in advance

Parent camera going nuts!

Hi,
I have a car that is all "grouped" together. That Group node is animated from point A to B. (the car)
I then am trying to "Parent" a Camera (that is sitting on the car), to the car itself. The camera follows the car great however, when I render it the image is Black (no picture) although there is an alpha channel of the shot, just no color pic. As soon as I "UnParent" the camera, it renders out OK.
If I parent it again, the screen goes blank again.
What gives??

has anyone had this problem?

Blendshape and Displacement

Hi, I”ve modeled out a character that has a look of a tree, now I want her to transform from a healthy looking tree into a rotting one. I’ve figured out how to do this by using blendshape.

Now my concern is, how will you animate the displacement map, and the texture? from a healthy tree bark to a rotten one. This is for my thesis in school. Would really appreciate all the help I can get 🙂

nCloth issue

Hello everyone.
I’m here to get some help about nCloth in Maya, because I can’t get the result I want even though I think the parameters I set should do more than what I need.

I’d like to make a newspaper fly away, but instead of that it just sticks on the ground plane.
To do so I have a model of a road that I use as a ground plane. ->nRigidShape
My newpaper ->nClothShape

The parameters I set up for the nClothShape :
-Collide and SelfCollide enabled
-Thickness 0.003
-No friction, bounce, Stickiness
-Stretch Res. 20 Compression Res. 10 Bend Res. 0.1
-Air Push Distance 48.0 ( I put this number for testing purposes to see if it would fly away instead of sticking to the ground plane)

The nucleus:
-gravity 9.8 direction 0 -1 0
-Air Density i wrote an expression

Code:

if (frame < 90 || frame > 220) {
    if (frame % 20 == 0)
        nucleus1.airDensity = 10;
    else
        nucleus1.airDensity = rand(0,2);
 }
 else
    nucleus1.airDensity = 8;


to get some nice movement.
-wind speed 10 direction -0.15 0.5 -0.3
-wind noise 5.0

I also constrained my ncloth with a Transform constraint, that i animated with an expression too on the strength and glueStrength.
Basically after frame 90 the strength is equal to 0 and so does the glueStrength.

I’m in centimeters in my scene and my Spacxe scale in nucleus is 1.0. I don’t know if can be the source of my problem.

Thanks for any advice you could give me

Maya2011: Rendering Shadow-Channel of hidden object

Tried this for hours yesterday and it’s driving me crazy. the shadow channel always produces a black image with a pure 100%-alpha channel and no shadow anywhere.

I did "hide" a simple cube, put a spot-light somewhere and placed a flat primitive below as a floor.
The beauty channel is fine.


scene with object visible


scene with object: display / hide / hide selected object


shadow pass settings

any suggestions? 🙂

Thanks in advance

Free Tutorial: Volume Caustics for Maya Users

Wanted to share this free tutorial aimed at the experienced Maya user. We designed to help people master some of the advanced tools which can sometimes be complex and take a while to master.

The tutorial takes a look at a complex scene setup that can be used to generate more accurate lighting effects using volumetric materials.

Normals flipped

Is there a script or a way in maya to get all the normals of multiple objects to face the correct direction. I have a complicated car model made up of hundreds of objects. A bunch of them have their normals reversed and are rendering black. Is there a way to fix this without individually selecting each object and reversing.

Thanks!.
