- Add fire (only tried it with fire FX so far) to a soccer ball. - Group them. - Even weld them (although I’m not sure what this does apart from making the objects have the same physics). - Then set the physics of the grouped object to normal. - Spawn as a spartan and the ball + fire will move. - Leave forge and start a regular match. - The ball will still be moveable but the fire will not.
I have the same sort of problem.
Built something similar to the Zanzibar draw bridge in halo 2 with multiple objects, grouped them, welded them, changed physics to normal. Bridge falls down like it should but when you load up the map again the draw bridge just falls apart when the level starts like it’s unwelded itself.
