E-on software released a new version of their real time renderer LumenRT 1.2 for SketchUp with several quality and reliability enhancements to improve overall performance and stability of LumenRT. The new version brings the ability to process larger models such as large structures or cities. Also, e-on software implemented a new auto-scale lightning feature which can improve the performance of render from 30% to 300% depending on the size of the models.
