Help with a random dot pattern metal

[Ramon Folguera]

Hi, 

anyone has this type of metal panel ling or can help me to do something similar please?

 

It has a random dot pattern bump and cutout.

 

thanks

That specific panel would be very hard to find, maybe check the manufacturer if they have any CAD models.

When  get similar design, I create the model using Substance designer or 3D Max native tool, it depend how many and different they are from each other.

BEst luck.

If you have railclone available you could create as many segments with different variations of bumps and holes as you need, then feed those into an array that randomly selects what element to use. For optimization you could also create opacity and normal maps from the resulting geometry and use those maps on "regular" geometry.

There are many tutorials for Railclone on the iToo site: https://www.itoosoft.com/tutorials?tag=railclone&page=1

 

If you do not have railclone available, you could skip the step that requires railclone, but go from creating the segments/elements and straight to the generation of normal and opacitymaps, and feed them into something like bercontile with a multitexture of your maps, to create a random pattern.
