You can now expose the attributes of your material in 3D Sampler so that the settings can be tweaked in other software when exported as .sbasr files! In this video, I’ll give you a quick demonstration of how it works.
I think that the ‘Exposed parameters’ update in 3D Sampler is a huge deal. Not only makes it easier to fine-tune your materials in external applications, but it can also speed up the workflows quite a bit. For instance, since 3D Stager is also nicely integrated with 3D Sampler and 3D Painter, you can build your materials in Sampler and send them directly to Stager to test how things will look like in a render engine:
Sometimes you might want to do some subtle adjustments to the materials when you are setting up your lighting and getting ready to render. With the new exposed parameters, you can update material properties like roughness amount or scratches quantity to suit the render you are going for.
In the case of this very basic example, I think the original wood material for the floor is a bit dark and maybe too damaged for the render. So I simply tweaked some of the material properties within 3D Stager and saw the updates in real-time to generate more contrast and simply brighten up the scene.
