I wanted to share with you a new tool we have been working on: Light Tracer Render
It is a physically based renderer similar to Cycles or Corona intended to be fast and easy to use. It can work right in a web browser and have native versions for Windows and macOS as well.
Light Tracer Render 2.0 is out and import CAD file such as IGES and STEP, and now has a new features for better caustics with path guiding and works well inside browser and seem very cheap than other render excepts the freeware ones like LuxCoreRender and Cycles inside Blender :) https://lighttracer.org/
