Short description of error
In some cases while working on the production files of Spring, the material turns pink for Eevee. This is usually coupled with long shader compiling. I saw this usually only occurring for big material setups that use node groups to some extend.
Both the jacket and rock end up pink when going into LookDev or rendering with Eevee. For the rock it seems to be the node group "rocks_frost" near the material output that is causing it. When skipping this node group the material renders fine.
The jacket used to render fine but then I put most of the textures into node groups and plugged them into the material on multiple locations. After that it ended up pink as well. By removing some of the node groups or muting enough nodes along the way, the pink material becomes fixed.
