You should contact Sketchup's Sales department and have them give you the full information. https://help.sketchup.com/en/contact-support/sales-question/form I do know of many people who have taken them up on their offer.

Keep in mind that the different rendering programs each have a "special" way the standard material from SketchUp is interpreted and / or enhanced, but these settings are not compatible with other rendering software, thus you would have to figure out and document an exact way to set various materials / textures in different rendering programs then render them to see how the end results compare.

Thank you - I will try these in the morning.
