Esse formato é obsoleto, mas ainda é aceito. It combined the
functions of INST
and TLIST
, taking a series of

the objeto under each transformation.
GROUP ... < matrices > ... unit { oogl-object }
is still accepted and effectively translated into
INST transforms { TLIST ... <matrices> ... } unit { oogl-object }
