• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Drawcall batching

Hi guys and "Arno :stirthepo

I have 78 lightpoles in a scenery placed with Instant scenery which would end up with 76 drawcalls.
How can I merge them so FSX read it as 1 drawcall. I have played Arnos tutorial 5 times and I end up
with black textures evey time and no Drawcall batching. What do I do wong ?

Your help is appreciated.

Hi,

All you would have to do is enable drawcall batching on the object and update your object library. After that they would be one drawcall.
 
Hoi Arno!

Thank you for your reply but I need a little more information.
I have one BGL for this lightpole and a placement file for all 78 objects.
The same thing goes for the 300 cars on six parkinglots.

If I open this "lightpole bgl/mdl" with MCX and make the "drawcall batching" will it
include all 78 lightpole's ?

If this work's I should get 20 more frame's, sounds to good to be true.

Dank U well for helping.

Hi,

Yes, you update the object in the library bgl and then fsx will combine all instances that you place in one drawcall while rendering. So you don't have to change the bgl where you placed the objects.
 
The placement BGL only refers to the object by its GUID. As long as your new object uses the same GUID as the original pole, then all 78 will be changed over and your drawcalls will be reduced. You will know the same GUID is used if the poles still show up using the new library BGL file.
 
Thank you very much Arno and Tom!

I think I got it now but it does not work on every object so I have to study more.
Roby is teaching me new things in MCX all the time and I must say" wow what a wonderful tool"

Take care and thank's a lot.

Note that drawcall batching cannot be done on models that contain LOD models, so it may not always work.
