It’s just like any other shader… select the Item in the scenetab, select the surface in the surfacestab, use the shader. And with this shader I never had the problem that you’ll only see the shader when you’re rendering, so… I’d guess something went wrong with downloading or with the installation… happens sometimes, computers are funny that way. I had some items that I downloaded more than once and installed more than once and then they ‘magically’ worked, when they wouldn’t before *shrug*
Allthough with shaders sometimes it’s a RAM thing too I guess… I sometimes have to close and open DS in order to be able to use shaders again. And you can overdo shaders *lol* I did it… it’s funny when you’re trying to make a bigger object dirty and suddenly no more dirtshaders for you.
I’d try reinstalling and if that won’t work, redownloading and reinstalling… and if that doesn’t work… maybe the download is borked with the work that is done to the products… there’s this downloadrepairtoll (I think from Kendall?) that’s been posted somewehre in this forum, maybe that can help in that case.
Hope you get it to work, it’s a really nice product
