with sidefx's materials from the orbolt store, I can't create all parameters in the obj's material pane without destroying references to the texture files. The materials render in red color.
I assume a problem with the map's opdef expression (possibly path or context related)…
yeah the expression is looking at the current node which changes from the shop to the object node when you ‘create all parameters’ option. You can get it to work by changing the expression to the following on the object node map parameters (it evaluates the Material shop path and gets whatever the shop it points to, and then it grabs the texture)
