Help needed for using Stencils

Post by Olivier » 18 May 2016, 12:10

Hello,

I want to achieve a complicated text effect with Stencil.

First, my text is divided in 2 parts, top and bottom. Both parts are going in using a rectangle stencil n°1.

After that my text is appeared, I would like to make it disappear using another stencil n°2.

How can I achieve this effect??

See attached file,

Thank you :)

Olivier

hey,

Not sure you can nest stencil nodes like that......
you could get the same affect using an alpha ;)

Thanks for your answer Chris,

I thought about this kind of solution but I really need to use a stencil, like that I can make much more different effects, like using a circle or combine more than one geometry to set my stencil...

Anyone else ??

What I love about ventuz is that there are so many ways to create thing, I made example using render target, masks, and text effects it may help it may not :)

Hi,

with stencils nesting won't work. The new stencil node will overwrite the old one.

Basically you've got two options if you want to use stencil:

1. use advanced stencil node, make complicated stuff, spend a day and get it done or not...
2. simply use a switch to toggle between your stencil setups.

I would recommend option 2. And yes, I'll give you a working example. Took 5 minutes, so probably a lot faster then option 1 ;)

Cheers,
rou

And what i have noticed:
NEVER animate size of a geometry during runtime! try ALWAYS to use an axis for changing the size! changing geometry eats resources because geometry needs to be recalculated!!!

Supertrue!!1!1one!

Actually the geometry has to be rebuilt, which is quick, but that might stall the whole system nevertheless. So just don't ;)
