Map compiler failure - func_illusionary error Thread - qc

Compiling a new map with hmap2 (related to darkplaces, many advanced map features supported)
and I saw this:

classname : func_illusionary
************ ERROR ************
Entity with no valid brushes

What happened?

I cut and pasted a brush that was part of a func_illusionary set.

"func_illusionary" is quake 1 map maker's equivalent of quake3 "detail" brushes.
The brush appears, gets lit, but does not affect vis data and is not solid.
Great for all the little bits that stick out and other wise clutter a map that (back in the day) made vis take forever to encode map data.

After pasting I assigned the brush a texture of "CLIP" - clip is a quake 1 map special - it is never displayed, but blocks all player / monster movement.
This allows func_illusionary to have solidity without hindering the visible set. It is also great for smoothing over rough areas that
can hold up or snag player movement.

But - you can NOT have a func_illusionary with a texture of CLIP!

Solution - select the new clip brush and tell radiant to "move into worldspawn" via the right click menu.
