attribute [flags] delete

[JEJongju]

i want to import vdb to unreal

but i cant.

because attribute order is lightly different

test.0001.vdb
0. flags
1. smoke
2. firefuel

test.0002.vdb
0. smoke
1. flags
2. firefuel

test.0003.vdb
0. flags
1. smoke
2. firefuel


so on


in ffxconverter, i can delete smoke or fire attribute but cant flags

i want delete flags(or import unreal correctly) . how can i?
