I'm not sure about upgrading to 2018. Money is tight, and I don't want to pay for a new way to surface in LW, when all I surface in is Octane. I'll need to do some asking around to see what some of the other benefits are.
Regarding changes in the SDK, Juanjgon, is there any chance of implementing a LW-like Gradient node? I know I haven't asked about it for a long time, but I still would love to be able to do gradients the same way the gradient node in LW does. (based on distance from object being the most important to me)
