Applying materials: Make sure you have faces selected when applying materials.To do this, right-click on the mirror object, choose Entity Info, and click on the Paint Bucket icon. Now, select the mirror object and apply the newly created material to it. Step 3: Applying the Material to the Mirror Object Play around with settings like roughness and opacity for more control over your material’s appearance. Create custom materials: Experiment with different reflectivity levels and colors to achieve desired results.Selecting materials: Look for materials that have high reflectivity values to achieve a realistic mirror effect.Use measurements: If you have specific dimensions for your mirror, enter them in the Measurements box at the bottom right of your screen.Ĭreate a new material for your mirror by opening the Instructor panel, clicking on the + Material button, and selecting a reflective material from the library or creating your own.Use guides: Enable guides ( View > Guides) to help you draw precise shapes.Use the line tool ( Tools > Line) to create a rectangle or any other shape you desire for your mirror. To begin, let’s draw the shape of our mirror. In this tutorial, we’ll walk through the process of creating a mirror in SketchUp, step by step. So, even after a material is changed it's still the same panorama, storing the original material assignment, used to render the reflection.Īfter changing the floor material from wood to terazzo the mirror still uses the original material.Creating a mirror in SketchUp can seem like a daunting task at first, but with a few simple steps, you’ll be able to add a reflective surface to your models and enhance their realism. The panoramas are captured only when the scene is loaded and used for the whole duration of the scene viewing. Light probe panoramas are not recaptured when a material is changed using the material picker, because this is a time-consuming operation and would cause the scene to freeze temporarily. Reflection doesn't react to material picker changes Mirror is using a light probe from the bathroom. Mirror is using a light probe from the room behind the wall, because there is no light probe in the bathroom. Finally, make sure there is a light probe placed in the room with the incorrect reflection. If you are using SketchUp, turn the mesh into a group or component, so the mesh is not merged with other meshes using the same material when the model is exported. Make sure that the object mesh fully belongs to the room. The object with incorrect reflection has been assigned a light probe placed in another room, so the reflection uses a panorama from another room. Reflection shows objects from another room Reflection in the TV screen is not aligned with reflection on the wall - objects are using different light probes. Try moving the closest light probes around or removing some of them. If two neighboring objects have inconsistent reflections they have been assigned different light probes. When the scene is loaded all objects in the scene are assigned the closest light probes such that the object is visible from the assigned light probe. Reflections on neighboring objects are inconsistent See the below "Reflections on neighboring objects are inconsistent" issue The seam is visible where two objects meet.Light probe bounding box aligned with the room walls. Light probe bounding box not aligned with the room walls. Make sure that light probe bounding boxes are aligned with the room walls. Seams visible in a reflection have usually one of the below causes: Light probe placed in front of the mirror. If a room has a mirror hanging on a wall the best result is usually achieved if you move the light probe in front of the mirror. Try moving the light probe around the room to find a position with least distortion. In most cases the distortion cannot be removed, but often it can be reduced. The most typical cases where the technique doesn't produce accurate results are described below. The captured panoramas are 2D and don't have full 3D information about the scene needed to correctly trace the incoming reflection rays, however in many cases approximating the incoming ray from one of the panoramas gives near-accurate results. The approximate technique is based on 360° panoramas captured by light probes placed in the scene. Rendering physically accurate reflections requires tracing how light rays bounce through the scene, which would be too complex computationally and lead to a very low frame-rate for a scene visitor using an average desktop or mobile device. Reflections in Shapespark may be inaccurate as they use a fast approximate technique suitable for real-time visualization on devices not equipped with a powerful graphics card.
