When it comes to lighting your subject, there are many different ways to do so and many different tools to help create and shape the light. If you do not have a ton of modifiers for your strobe but you do have a V-Flat, here's one way you can use the V-Flat to create soft light in your shot.
In this video, photographer Jeff Carpenter uses the portable V-Flat from V-Flat World in the studio along with a single Paul C Buff DigiBee flash unit as his light source. This combination produces a large spread of soft light onto model Leah Tobak to mimic a nice natural light look. If your studio doesn't have windows for natural light, this is one way to achieve a similar look in your shots.
The setup is fairly simple and not a lot of equipment is needed, but placement is important as Carpenter mentions how the distance and height can affect the lighting. Both of those needed to be considered to produce the desired results along with your subject's placement, like modeling while sitting on the floor as shown in this video.
