Error using only some assets

Skatter Bug reports
1

SketchUp version : Pro 2020
Skatter version (Skatter dialog > Options > About) : 2.1.7
OS : Windows 10
Description of the issue :
Are you able to reproduce the issue every time? (If yes, how?) : Yes
Error in Ruby Console? (Window > Ruby Console) :

When I try to render a scene using any of the free assets such as the skatter grass I get an error message saying: "unfedined method ‘[]’ for nil:NilClass C:/ … / ruby/live_scene/proxy_materiual_20_:in’export!’

If I delete this instance of skatter and try using another downloaded asset there is no issue.

I am able to reproduce this with any scenes, also a completely new file.

Which version of V-Ray are you using?

3

V-Ray for SketchUp 4.20.03

4

Oh I see.
Assets from the 3D Bazaar Marketplace are compatible with V-Ray 5 and above.

But how come some of the assets work and some doesn’t?

Sorry I misspoke, most assets are compatible with V-Ray 4 indeed. The ones that were created by us (“by Lindalë”), like the Skatter Grass, are compatible with V-Ray 5. It is explicitly stated in their description: “compatible with V-Ray 5+”.
