I have Vue 8.4

I can't find info about appliing masks in Vue

Can you apply a mask in vue like you can in photoshop?

Lets say I have a sphere primative opened in Vue and I want to mask part of it (like maybe a white star shape made with displacment material on the sphere so that star sticks out a bit)and apply a smooth black non displacement matierial outside the star shaped masked area of the sphere. So I wind up with a black sphere with a raised white star (star raised because of displaement mat) Can that be done in VUE ?

Thanks For any help.

you would use an alpha or transparency map for this particular material. Create the texture in say, Photoshop, and apply it in Vue as a new layer.

Do you know of a tutorial that covers something like that?

Or any tut that shows masking with in view?

I did not see an obivious one at Geek at play.  I could have missed that though (there are so mant tuts, if anyone has a link to specific tut, that would great

Thanks for the reply

Maybe this helps:

I have quickly made a black and white flower shape in PS and save it as .jpg. Then I add this "mask" as a projected texture map node to the alpha channel. See the screen shot above for how I set it up (click for larger version). Then I just added some displacement via a constant node. The mask in the alpha channel has the effect that only the black part of the mask will show the color and displacement. What you get in this case is a blue raised flower shape. Does this make sense?

Thanks for posting that, very interesting.

What I'm really after here is way to mask of part of the sphere free form using the cursor to paint or draw the star shaped mask and put one procedual material outside the star mask, then invert the mask and and put a seperate and differnet procedual material in the star mask.

Then I would just assian some displacement amount to whaever procedual material inside the star shape.

However I can't find any masking tools in Vue.
I've looked online and in the pdf manual.

In my question I used terms like Sphere and star and black and white, just to try simplfy my question. But I think that's working against me now. So I'll just say what I'm doing.

The real project:
A styleized 3d Tree Trunk with seperate sphere embedded.
Sphere is to look somewhat engluffed by Tree Trunk as when a branch is cut off and the tree heals around the edges of where brnch used to be.

I thought I could just model the tree trunk in Zbrush and import that into vue and give it a nice procedual trunk mat.
Then stick a view primative shere into the truck with just a little of the sphere sticking out. Sphere is a lumious procedural alien mat of some kind

Where the sphere cuts into the trunk would not very natural so that's where I need to freeform mask So I can precisely draw or paint that unnatural intersection area maybe with varient of the trunk material has more displacement so the trunk in that area could appear to swell up and engluf the edges of the sphere.

I thought rather than model the Engulfment area in zbrush that maybe I can accomplish that part by the method I mentioned using Vue if there is mask tool assianed to the cursor.

I don't think I can figure line up what need where I need it by using your alpha process.

Any thoughts.

 

 

This can't be done in Vue. What you could do is give the sphere a 100% transparent material, then add a non transparent layer to it, and play with environment settings to show the second material (slope/altitude/orientation).

Ah, now I see what you are trying to do. While this is not directly supported, you could try to do the following:  Use a terrain (rescaled, rotated and clipped) placed at the transition zone. That way you can use the terrain editing tools and terrain painting tools to "model" and paint the transition to your liking. With the "show scene" option you'll be able to see the tree trunk in the terrain editor. Above is a screenshot of a quick mock-up using a sphere and cylinder.

Hey, this is fun. Here is five minute example with colors. Can certainly be improved by more careful shaping and painting.

Thanks

That end result and your method of getting there will work for me just fine. Probably even better for this project than my idea. I'm glad there is a way.

Still I wish there were photoshop like masking and painting tools in vue for material application on everything in Vue plus imported models. That would be really useful to.

Maybe Vue 10

 

Thank also to bruno021 for the reply. I can see some possibilities there to.

Well that was fun and I like the result I got here. Learned some cool stuff today.

Thanks for the help

Awesome! That looks great.
