vray demo for 3ds max

Recently i thought, that it would be nice to have vray demo in my max, for me to be able to read/convert some of vray materials that i encounter from time to time. I do not plan or want to use vray or any of it’s feature for a split second, apart from material preview. I went to chaos page and saw that there is time limited trial version. Question is, what’ll happens when trial period will expire? Do i have to uninstall vray? Maybe there is some other way to convert materials, without having vray installed?

Just an early warning, lets not discuss any cracks, licencing flaws, bugs, or exploits concerning our vray friends here…
