Material effector

[jakerupert]

I am trying to use a material effector with a transparent material to make a part of a modell invisible in a chor

and can`t get it to work.

Does anybody by chance have an example project or mini tut for this matter?

Jake - I have never really played with material effectors - but what I just did was make a simple test case:

 

1) create a material that the only attribute set is transparency = 100%

 

2) create new material effect

 

3) drag material onto material effect

 

4) create chor with model to be made transparent

 

5) add material effect to chor, moved it so it partially covered model

 

6) played with size, fall-off and type (cone, sphere, box, cylindar) of material effect (in the object - not the instance) to see how different params affected the effect. Each type behaved differently (so you will have to play with params) - In the image the cone shape made the model transparent where it intersected the model. (Cone doesn't really look like a cone to me)

 

The material effect will impact everything that it touches (intersects) - so you will have to play with size, shape, etc. I deleted ground plane in this case.

 

What problem did you run into?

I recently posted a material effector project but not to make something invisible but Nancy has the basics just remember the the material effector will effect any model it touches

Hi Nancy,

 

Thanks for your help.

 

Managed to use a material effector boxshaped to make that red zack line in the chart visible one by one.

Nice - and a great use for a Material effector - so I thank you !

 

I've always wanted to do a "3D paint stroke" type animation - and this would be a good technique to use for some aspects - I had been thinking of manipulating CPs instead - but this would work better for some situations ... Thanks for the inspiration.

 

Neat!
