I'm trying to make a rounded 3D cube in photoshop:

enter image description here

The right one is what i wanted to replicate in Photoshop, the left one is what i could do using the 3D feature in Photoshop (3D -> New extrusion 3D from layer).

How can i make the corners of the cube rounded, like the right one?

  • You can not. Photoshop is not a 3D editing application.

If you have the extruded object already in PS and it's rasterized, you can continue there. This receipe is useless for vector objects.

Make a couple of copies of the object without any background. Add a layer which has a color which do not fight with the object:

Merge one of the copies and the new background

enter image description here

Apply Gaussian blur

enter image description here

Select the emptiness around the copy and refine the edge to good shape:

Use the selection in the blurred layer to kill the background
