Hi,

I have a question about displacement map, how can I generate a displacement map that lead to create this kind of details: 👇🏻

These will be used for cnc cutting machine.

Thank you.

You would need high resolution mesh, then you bake it to lowpoly mesh to get displacement map.

Or you can just paint it in photoshop, for example, but result would most probably be worse.

Thank you for reply.

I remember that one day I found a site that generate a displacement map from images provided, but I no longer remember its name. I was looking for a method that would replace manual modeling with another quick method.

Your best bet would be some kind of neural network, otherwise you will have a classic problem of converter not knowing if dark pixel on your source photo is a shadow, indentation, paint etc. For example

will provide a messy result, unless you can feed it several photos with lighting from different sides.

Thank you very much, I will take a look of that link and tell the result if I found it.
