Trees trunk material

SketchUp version : 2019
**Skatter version ** (Skatter dialog > Options > About) : 1.4.7
**OS :Windows 10 **
**Description of the issue : Ats some point the proxys of the trees render wrong. The trees trun material is replaced by the leaves material wich make them green and partly transparent. When I open the group of trees in SU the trees billboards are also assigned with the leave material. Removing the material from the billboards wil render the trees without any material. **
Are you able to reproduce the issue every time? No (If yes, how?) :
Error in Ruby Console? (Window > Ruby Console) :

What render engine are you using?

Hey Thomas,

I’m using V-Ray for SketchUp 4.00.02

This is very strange.
Does it happen in a brand new file?
