An update just in time for the new SketchUp 2018. Info: http://www.artvps.com/ Changelog (take some comments with a grain of salt. I use Win7 SP1 whichis older than 8.1): Shaderlight 2018 has full support for SketchUp 2018. Improved rendering of Transparent materials Most of the Transparent materials types use a new, physically-based model to correctly account for the absorption of light as it travels through the material. This means that thicker objects absorb more light and appear more intensely coloured and darker than thinner objects and provides more realistic renders of deep bodies of water and thick glass objects, for example. The new model is used by the Transparent Solid Glass, Solid Frosted Glass, Liquid and Diamond material presets. To give a greater range of transparencies, SketchUp’s opacity slider is now used to modulate the amount of absorption in these materials. In previous versions of Shaderlight, the opacity slider in SketchUp’s material editor had no effect on the Shaderlight render. Please note that the appearance of the affected transparent materials is likely to change from their Shaderlight 2017 appearance. You should be able to get something that looks similar by adjusting the colour and/or opacity of the SketchUp material, but some objects may still render quite differently because the thickness of the object is now taken into account. System Requirements In this release, we are ending support for older versions of SketchUp and Windows/macOS. Shaderlight 2018 is now supported on Windows 8.1 or later, macOS 10.9 (Mavericks) or later and SketchUp 2013 or later.
