3ds Max 2020.3 is focused on providing you with more predictive tools that perform the way you expect. With 2020 through 2020.2, we brought you extensive updates to chamfer workflows. In 2020.3, we’re adding many of those improvements to EditablePoly objects. Our ATF (Autodesk Translation Framework) updates include Sketchup improvements so you can bring in content with even higher fidelity along with newer JT formats supported. You can now also view Arnold lights directly in the viewport.
