The color turns purple (like when there is no material detected. I have 10 textures combined with mix nodes, until then everything all right. As soon as I put the 11th texture, the object turns purple in 'material preview' mode. Despite that everything works render-wise. Plug a series of textures combined with 'mix' node and input into a '"factor" of a 'math' node, according to the attached image.{F12740219} [Please describe the exact steps needed to reproduce the issue] [Based on the default startup or an attached .blend file (as simple as possible)]
