Hi!I'm from Finnish Scenery Designers and I'm working on gates for EFHK scenery. What I would like to do is an API macro for the gate and different LOD stages for it so that I could use the same API macro for all the gates.I've created a 3d-model for the gate on gmax and two different LOD models for it which I've exported using MDLCommander to get x-files for both of them. Then I created the BGL and tested it in FS and LODs work just fine.Now I want to compile the gate into a API macro and I'm using FSregen for this. When I compiled it into a macro only another of the LOD stages got compiled and different LOD stages naturally won't work in FS.The orginal asm source looks like this:-------------------------------------------------------------;compile with BGLC /BGL D:EFHK-scenerysceneryportti.asmheader label word dw 0001 ; 00 World set number dd 000664911H ; 02 North bound dd 0006648EFH ; 06 South bound dd 011C1556DH ; 10 East bound dd 011C1556BH ; 14 West bound dw 20 dup(0) dd (offset OBJECT_DATA) - (offset header) dw 33 dup(0) OBJECT_DATA label word db 21 ;;LATBAND_REL dw 03324h ;;lat min (inclusive) 512M units dw 03325h ;;lat max (exclusive) dd (offset OBJECT_0) - (offset OBJECT_DATA) db 0 ;;EOL OBJECT_0 label BGLCODE db 12 ; NEAR_FAR_HUGE_OBJECT_HEADER dd 000664900h,011C1556Ch ; latitude,longitude db 100 ; image power dd (offset OBJECT_0_END) - (offset OBJECT_0) OBJECT_0_START label word IFIN1 OBJECT_0_FAIL, image_complex, 2, 32767 ADDOBJ OBJECT_0_SCALE SHADOW_CALL OBJECT_0_SCALEOBJECT_0_FAIL label BGLCODE BGL_JUMP_32 OBJECT_0_END OBJECT_0_SCALE label BGLCODE SCALE_AGL OBJECT_0_RETURN, 10000, 19, 131072, 000664900h, 0BCE1h, 011C1556Ch, 03DD2h, 0, 0 BGL_CALL OBJECT_0_BEGINOBJECT_0_RETURN label word BGL_RETURNOBJECT_0_BEGIN label wordmodel_outside label BGLCODE VAR_BASE_OVERRIDE VAR_BASE_GLOBAL IFIN1 model_shadow, SHADOW_FLAG,0,0 IFSIZEV LOD_1, 301,1000 ; lod = 150.000000LOD_0 label BGLCODE BGL_JUMP_32 LOD_0LLOD_1 label BGLCODE BGL_JUMP_32 LOD_1Lmodel_inside label BGLCODE BGL_RETURNmodel_shadow label BGLCODE IFSIZEV SHADOW_1, 301,1000 ; lod = 150.000000SHADOW_0 label BGLCODE BGL_JUMP_32 LOD_1LSHADOW_1 label BGLCODE BGL_JUMP_32 LOD_1LLOD_0L label BGLCODE include D:EFHK-scenerysceneryportti_0.asmLOD_1L label BGLCODE include D:EFHK-scenerysceneryportti_1.asmOBJECT_0_END label wordEOF-------------------------------------------------------------And the one created by FSregen like this:-------------------------------------------------------------; Library Compiler - fsregen v0.31b by G.Ioannu ; Freeware.

FsRegen only takes one version of the object, I think the best workaround is to just make two GMax models and add them both to the library (with a different ID). Then change the API so that it calls one of these objects depending on the range or so.Arno

Yes, sounds wise. How can I make an API macro which appears only if the distance is over 500 meters?

Try to replace the line that calls the object by something like this:IfVarRange( :lowdetail 33B 0 500 )CallLibObject( 0 12345678 12345678 12345678 12345678 ) ; high detail objectJump( :further ):lowdetailCallLibObject( 0 12345678 12345678 12345678 12345678 ) ; low detail object:furtherArno
