Sunjammer's tutorial makes mention of 'layers', however I think this term is misleading. In my experiments with his system, it does not seem to be possible to layer tilemagic effects atop of each other:
ApplyEffectToObject(DURATION_TYPE_INSTANT, EffectVisualEffect(VFX_DUR_GLYPH_OF_WARDING), GetObjectByTag("jmt_glyph001")); //Glyph at the player's entrance
SJ_TileMagic_CoverRange(OBJECT_SELF, SJ_TILEMAGIC_ORDINARY_CAVE, 0, 1, 6, 7, -5.40, TRUE); //Cavefloor Tiles
SJ_TileMagic_CoverTile(OBJECT_SELF, SJ_TILEMAGIC_FEATURE_UNDERDARK_WATERFALL, 5, 4, -2.45, TRUE); //Waterfall Tile
SJ_TileMagic_CoverRange(OBJECT_SELF, SJ_TILEMAGIC_ORDINARY_WATER_BLUE_1, 0, 1, 6, 7, -2.43, TRUE); //Water Tiles
This results in only water tiles being present ^
Since this is the case with this system, is there a possible workaround? Am I using the system wrong?
