Show products from specific vendor (in template)

I’m building a page template and I want to build a section that shows products from a specific vendor. I have this working code that shows products as long as they are in any collection, which can be used as a base but I can’t seem to change it so that it shows products from a specific vendor only:


    

        {%- for product in collections['all'].products limit: 4 -%}
            

                {% include 'product-collection' %}
            

        {%- endfor -%}
    

Thanks for your input!

Is it okay to bump this up? I have not found a solution for this yet.
