• 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.

I am trying to find the original detailed documentation on FS9 BGL Opcodes. I downloaded BGLC_9 but can't find in the html the detailed explanation

For example, extracted from: http://www.aerodynamika.com/cgi-bin/yabb2/YaBB.pl?num=1153166310/10

BGL_TEXTURE_LIST (0xB7)
Provides a list textures to use in displaying a 3D object.

Length variable
ENUM16 opcode BGLOP_TEXTURE_LIST = 0xB7
UINT16 count Number of textures in the list.
UINT32 reserved Reserved variable and MUST BE 0.
TEXTURE texure[] List of textures.

Each TEXTURE contains the following:
UINT32 cat Class/type of texture, see the “Texture category values” section below.
UINT32 color Fallback color (B G R A ).
UINT32 reserved Reserved variable and MUST BE 0.
FLOAT32 texture_size Size in meters of texture, used for mip selection.
STRINGZ tname[64] Texture name ASCIIZ string.



EDIT: Found it at http://www.cfgse.calebflerk.com/SCASMOpCodes.htm

Question, are these OpCodes still supported by P3D? What has been P3D statement on backwards compatibility?

Thanks!

After some research, opcodes are supported internally in P3D v3.4.

The only thing I could not make work is the shadow casted on terrain by rendering objects via FS9 instructions.
