From PBR to DSPBR in SOLIDWORKS 2026: Understand the Advanced Material Support in SOLIDWORKS

-

SOLIDWORKS 2026 introduce a major visual upgrade, modernizing background scenes, lighting, materials, and rendering. These improvements make models look more realistic, but files created in SOLIDWORKS 2025 may appear warning when opened in the SOLIDWORKS 2026.

The update introduces a physically based rendering system and enhanced lighting, focusing on:

  • DSPBR (Physically Based Rendering) Appearances
  • Updated Background Scene Library

This blog highlights the key visual changes and provides guidance to update your existing projects for consistent, high-quality results.

DSPBR (Physically Based Rendering) Appearances

SOLIDWORKS 2026 supports DSPBR appearances, creating a seamless transition when you open designs in SOLIDWORKS Visualize to produce high-quality, photo-realistic images.

Updated Background Scene Library

SOLIDWORKS 2026 introduced a more background scene library, designed to improve lighting accuracy and make models look more realistic.

  • High-resolution HDR environments for sharper, more detailed backgrounds
  • Studio and industrial lighting setups with improved realism
  • Outdoor scenes with natural light and accurate shadows
  • Enhanced image-based lighting optimized for DSPBR materials

Example: Background Scene Transition from SOLIDWORKS 2025 to 2026

Background Scene Transition from SOLIDWORKS 2025 to 2026

Suppose you used the “Backdrop Grey with Overhead Light” scene in SOLIDWORKS 2025. When you open this file in SOLIDWORKS 2026, a pop-up warning appears stating:

"The scene configuration is not supported. The default scene will be used."

Background Scene Transition from SOLIDWORKS 2025 to 2026

This happens because the legacy scene is no longer available in the updated library. SOLIDWORKS 2026 automatically applies a default scene to ensure your model is still visible, but the original lighting and background are replaced.

To restore or customize the scene, you can use the Edit Scene feature in SOLIDWORKS 2026. This allows you to:

  • Choose a new HDR background from the updated library
  • Adjust lighting, reflections, and shadows to match your desired look
  • Save a custom scene for future use or team-wide consistency

This workflow ensures that older models remain compatible while taking full advantage of the enhanced visual realism in SOLIDWORKS 2026.

Removal of Legacy Background Scenes

In SOLIDWORKS 2026, several older background scenes have been removed from the built-in library. These legacy scenes were removed because:

  • They used Low-resolution textures, limiting visual quality
  • Lighting values were inconsistent, causing unreliable results
  • Highlights and shadows were not calibrated for physically based rendering (PBR)
  • Results varied across different hardware and rendering setups
  • They produced inaccurate reflections on modern materials.

SOLIDWOKRS TECH TIP - SOLIDWORKS PROPERTY TAB BUILDER

-
Image
The Property Tab Builder is a stand-alone utility that you use to create a customized interface for entering properties into SOLIDWORKS files. Traditionally, designer's use to modify the drawing template to insert custom property such as Description, Part No, Material, it’s a manual method. so, designers have to modify the custom property or metadata on each time, simultaneously BOM creation is also manual which increases a run time and errors in BOM table. It's also delayed the release of entire project. Three ways to create a customized interface for property template. In the SOLIDWORKS software, on the Custom Properties tab in the Task Pane, click Create now. In the SOLIDWORKS software, on the SOLIDWORKS Resources tab of the Task Pane, click Property Tab Builder From the Windows Start menu, click All Programs > SOLIDWORKS version > SOLIDWORKS Tools > Property Tab Builder version. To create the property tab, you will need to first create a new fil...

Confused With Wire/Cable Harnessing? - Harnessing Technology By SolidWorks Electrical

-
Image
SolidWorks Electrical is an intuitive and powerful tool which takes care of wire and cable harness design and create the flattened view with automatic updated BOM/Cut. Engineers need to put more thought into thinks like wire length, bending radius and routing. As wiring harness become increasingly complex and an important part of design we are in need of a powerful tool to ease our design process, this is where SolidWorks Electrical comes into play. Today in Automotive sector there are many more computers and Electronic Control Units used in vehicles today. These ECU are used to control the transmission, and other major devices of the vehicle and they have to be connected via wire harness in order for the system to work What is Wire Harness? The wire harness is compactly bundled wire which plays as the conduit for transmission of control and power signals acting as the “Central Nervous System of a vehicle”. When designing a new product, engineers focus mainly on f...
