Missing Nodes

[bazil14]

Hello,

I am using vb30 and I am having a problem with whole material tree's going missing every time i save,
If i recover an auto save its there, but if i save manually they are deleted.

Did you make those material trees in an older build? (from before June of this year?)
You may need to update to the current version of vb30 and re-build your nodes. There was some change in the way nodes are accessed in Blender from earlier versions, so if you have node setups that you created in an older build, then those can get lost. At least that was my experience. I found it was simpler to just rebuild the nodes from scratch and then you can be sure they comply with the current format. You can try converting the shaders, but not exactly sure if it fixes the old nodes that were used.
