Flashbenders for studio strobes?

I don't know if this is possible or not.
I like the flashbenders on my speed light, so I wonder if I can do something like that for studio strobes.
I know I can use barn doors, but I interested into the light shape that I can get with the flashbenders.

What shape is that?

Seriously, they're just white fabrics that reflect light in a diffuse manner. Their shape is designed to avoid wasting the very directional light that shoots out of a flash unit, but the spread of light coming out basically will cover an entire hemisphere.

There are "scoop" type reflectors for studio strobes to light a backdrop from the floor, and generally a range of choices in standard reflectors to restrict that hemisphere a little bit (to avoid spill with umbrellas) or a lot (for more distance).

Can you tell us more about what you want to achieve?

so if I make a "snoop" or something like that, without a perfect circular shape (simulating flags). That is what I want to achive.
I saw Frank Doorhof did something like That, not perfect shape, and also direct the ligh as he had flags. In other words if he didn't want to light an are he molded the flash bender and he got the "random" shape. He used speed lights, but I would like to use studio strobes, because that is what I have studio strobes.
My studio is not that big, so if I can create shadows without flags, I save on space.

okay, that makes a bit more sense than trying to make a flashbender style bounce card for a studio flash. why not just make a tin foil snoot that you can mold to your desired shape. Start with regular snoot then wrap foil around the end to shape it. I suppose if you had alien bees or some other similar mount you could cut a hole in an aluminum pie pan to start as your base and then bend and shape it as you like, adding additional material (costruction paper or foil) to get the shape you wanted.

That is a great idea!!!

Speedlites have a parabolic reflector behind a linear flash tube and a fresnel lens in front of it. They are designed to make the light very directional - to maximize the efficiency of the light produced by aiming it all basically in one direction to light the rectangular area in the frame. Various modifiers are used when you want something different - less directional, more diffuse lighting.

Studio strobes have a donut shaped flash tube that will throw light in all directions. We use modifiers to (among other things) make them more directional.

What this means is that it will require very different modifiers to accomplish the same effect, depending on which type of light you start with.

That said, the pie pan and tinfoil approach is probably a good way to experiment. You will get a feel for the shape you need, and you can then search for a more elegant solution.
