After the 3D software completes the model, it will generally render the effect in the rendering software. Generally, the concave-convex feeling you need is attached to the material, polished, and the concave-convex feeling will naturally exist.

If you make a plane, how to render the concave-convex feeling in the rendering software is also to realize the concave-convex by pasting materials with concave-convex feeling and adjusting the effect.

There are many rendering softwares (AE.VR., KEYSHOT) and some softwares only have rendering functions or plug-ins (RHINO.soldworks, zb, 3dmax, etc.). ).

Personally recommend VR and Keyshot, the latter is simple. I hope to make the effect you want.
