We are continuously expanding our vMaterials catalog. We are adding content in all of the available categories, one at a time. If you are missing a certain material from the our catalog, here is the place to ask for it to have it added. We gladly take suggestions and add them to our wishlist of materials to create. This helps us creating the materials that you - the users - need for your daily work.
When you post a material wish in this thread, it is very helpful for us when you also attach some reference imagery of the material that you have in mind. That way we get a good idea what you expect the material to look like.
