Hi all
Background: em…I tried to build an emitter package for some effects on my weapon and I decompiled a test uc script and made it very simple for testing build. I put the .usx files into staticMeshes folder, put the .utx file into textures followed all the UnrealED rules. Any information is appreciated.
The warnings:
Engine.MeshEmitter: Unknown property in defaults: Opacity=0.350000
Engine.MeshEmitter: Unknown property in defaults: CustomMaterials(0)=Texture'Editor.Bad'
TestEffect.weapon_anta_thrower: Unknown property in defaults: bSunAffect=true
TestEffect.weapon_anta_thrower: Unknown property in defaults: SwayRotationOrig=(Pitch=393146,Yaw=309788917,Roll=0)

And the code:
class weapon_anta_thrower extends Emitter;

defaultproperties{
Begin Object Class=MeshEmitter Name=MeshEmitter187

I've never seen that an object can be defined in section defaultproperties.

It is UT2004, UT3 or god know what else...
