Simulations let you apply your designs, colorways and colors to models in 3D and in real conditions. With Inedit's Photoshop Plug-in neoTextil nT VirtualVision (https://www.inedit.com/en/productos/neotextil/), you can modify the simulation objects with grids and shadows to get the 3D effect of your designs. If you wish, Inedit may provide you with ready simulations.
You access the Simulations clicking on the button situated at the top tab bar. On the left you can see all the objects without simulations you have loaded and on the right the designs, colorways or color library.
