• 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.

FS2004 Seasonal texture

Hi to all,
i'm creating 4 different ground texture for my airport based on season. I read few minutes ago, the wiki about Seasonal textures (ASM tweak). But, for me it's very long procedure and difficult, because my project contain 19 bmp texture (for all 4 season are 76). Ok... First one, i don't understand the tweak, but i find another simple procedure on this forum:

IFIN1 OBJECT_0_FAIL, SEASON_CYCL, 2, 2

where: 2, 2 are for Summer
0, 0 for Winter
1, 1 for Spring
3, 3 for Fall

--- groun poly creation: i have created with GMAX 4 bgl files with different seasonal texture (xxx_WI.BGL, XXX_SP.BGL, XXX_FA.BGL, XXX_SU.BGL)
--- After this, i have edited the 4 .ASM files (not _0asm.) with this lines:

OBJECT_0_START label word
IFIN1 OBJECT_0_FAIL, image_complex, 2, 32767
IFIN1 OBJECT_0_FAIL, SEASON_CYCL, 2, 2
ADDCAT OBJECT_0_SCALE, 8
OBJECT_0_FAIL label BGLCODE

Its works fine and the textures change when change the season. I want to know if this procedure is correct.
Another question. Can i make a invisible runway (only RWY and PAPI LIGHTS) above the terrain because with the custom poly, the rwy of AFCAD is covered? If yes, how?

many thanks to all and sorry for my bad english
 
Hi,

Your approach to tweaking will also work. The article is for tweaking so that you have all textures in one BGL, but that is a little more work.

Hi Arno and thanks for your reply. the question is if my procedure (4 bgl files for 4 season) is correct. The BMPs files are with Alpha channel, i need to save its in DXT1 with Alpha (650 Kb) or DXT3 (1.33 Mb)?
Another question, please : I have tryed a custom runway with scasm code. It work fine in FS2004 and in FSX too (no frame rate problems), but my runway surface (-1, 1, 2, etc) don't is invisible. When i write in Scasm code - 1, i have a grass runway but non Invisible. How i make an invisible RWY only PAPI and rwy lights?

Many thanks Arno

Best regards
 
Hi,

Yes, your procedure is fine.

For the textures it depends. If your alpha channel is only black or white, DXT1 will be fine. Else you should use DXT3.

I can't answer the question about the SCASM runway, it is a very long time ago I tried to use that technique.

thanks again ;) . Do you have another technique for rwy lights only?

This tweak, while simple to accomplish, seems to strictly apply the astronomical seasons. Is the only way to effect a specific date (day number) for a season change acheived by using the day of the year variable 038A in the asm _0 file?

Greg
 
That is correct. To match the terrain seasons you need to use the day of the year variable.
