Material NATURE/BLENDCONCRETETOGRASS002 uses unknown detail object type tf_forest_grass!

[Engineer of Stuff]

I got the compile error:

Material NATURE/BLENDCONCRETETOGRASS002 uses unknown detail object type tf_forest_grass!

How do I fix this error? I read somewere that this is related to the Ultimate Mapping Pack by A Boojum Snark, which I have installed.

The error is harmless from what I'm aware of. It's just used to add some level of detail to a displacement like the grass sprites you see in Dustbowl and such.

Just an error that means that detail sprites won't show up on displacements and stuff.

To fix, just go into your map properties and changed the "Detail .vbsp file" to "detail_trainyard.vbsp" and "Detail material file" to "detail/detailsprites_sawmill"

(make it look like this basically except change the material file to sawmill)

This page gives some nice examples of what the different material files look like and all that.
