Low poly art would usually be made with 3D applications such as Cinema 4D to build three dimensional models, but we can create similar styles in two dimensions directly in Illustrator. Follow this tutorial to create a cool low poly mountain illustration using vector paths. We’ll add gradients to simulate a 3D effect then take the design into Photoshop to polish it up with cool textures.
Here’s the final artwork we’ll be creating. The polygonal mountain will be created using Illustrator’s accurate vector tools then brought into Photoshop for some texturing to really bring it to life.
Create a new Illustrator document and draw a rough mountain outline using the Pen tool. Make single clicks to generate straight lines between each point and follow a curved path for the bottom edge to help with its 3D appearance later.
