Hi QStuff
I’m afraid Shaderlight 2017 doesn’t support SketchUp 2018. To use Shaderlight with the latest version of SketchUp you will need to upgrade.
Customers who purchased Shaderlight from September 1st 2017 are eligible for a FREE upgrade to this new release for a limited time.
Existing customers not eligible for a free upgrade will receive a 25% discount when upgrading to the new release using the promo code SL18UP.*
*Offers expire on December 1st 2017.
