We have discovered an issue with Substance Designer 5 and the Substance Engine V5.
Unfortunately iClone 6 currently does not support Distance, Gradient (Dynamic), Pixel Evaluator, SVG nodes. Using these will crash iClone 6 if the Substance project is using Substance Engine V5 nodes.
To resolve this issue, you will need to switch to Substance Engine V4 compatibility. Please see below for how to do this.
We are looking to correct this in an update, but for now iClone 6 is only fully compatible with Substance Engine V4.
Please do accept our apologies for any inconvenience caused.
