• 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.

blurry textures

Time for me to go crazy :(

I'm rebuilding an airport, which is basicly new buildings, new textures, trees and so on.
Well...all went well until I noticed that when I'm flying away from the airport,
all ground textures become blurry. I first thought my video card went nuts,
but this thing only happanes in this area. I started deleting bgl files from my scenery to zero in the file that cause the problem. Nothing, same problem.
The only things that helps is removing the entire scenery. :banghead:

I'd be happy if someone could guide me where to look in order to solve this

Hi Neal.

I'm sure the problem lies with a texture or two that is either missing or in the wrong format. Impossible to tell without having the BGLs to test.

You could attach a zip to a post, and maybe that would work... but first, try to add BGLs to a project's "scenery" and "texture" folders until the blurries return... then you'll know generally where to look.

And to add to Dicks reply. When you wait for a few seconds, does the blurryness reduces? It could be that it is just the loading time that is longer.

Other question is obviously did you change anything to the landclass or maybe even place texture on ground polygons in your new project?
 
thanks guys

I think I found the answer ( knock on wood )

I have made an experimental object named " vip_LOD_80". This object
had no dummy attached to it and I completely forgot about it. It was
small enough to be over looked. The strange thing is that I have removed
the bgl file that contain this object, and the problem was still there.
My guess is that the object somehow still remaines registerd in the system,
unless the whole scenery is removed. :cool: Anyway, the object was
deleted and so far all is fine !

I would like to end by saying thanks to this great forum. I have learned so
much since I started visiting here. I'm close to finishing my 2nd version of
my scenery, and things look so much better now. Just as an example :
"kill_shadow"..."99 opacity"..."mdlteaker "...ahaaa life is good :)

I never made 'vip_LOD_80' but still blur on it.
I already place my bgl one by one on scenery folder but it can help.

I'm sure there is an object should be remove but where is it?????
 
HELP!!! mayday.. mayday.. Arnoooo...

I'v got still blurry texture...

with gmax

without gmax

what happened?
should I send my gmax file to you Arno? :D
 
I am having the same problem xbuddy....as soon as I add any GMAX object, the textures start out just fine, then go blurry, and then clear up after a few seconds.

I have a landclass file that was created with EZLandclass. If I remove all bgl's except the flatten bgl and the landclass bgl, the textures are fine. But as soon as I add a GMAX object, the textures go crazy.

All textures are stored in DXT1.

Examples will be posted in next thread................

Hi,

Have you been able to pinpoint the problem to one signal GMax object or is it any GMax object that is causing these problems for you?

Also, you wrote you had made your own landclass file as well. When you remove this file, do the default texture blur as well in that case?
 
No, it happens when I include ANY GMAX object, even a simple low-polygon four-sided house.

As for the landclass, it was created using EZLandclass and that bgl does not appear to be the problem. When I remove all bgls from the scenery file except landclass, the problem goes away. Only when I add a GMAX object does it re-appear.
 
Hi all,

I sometimes have the same probs with gmax sceneries. But I think it´s not a gmax problem, more a FS problem: Try to change your mip mapping quality settings at the display options to a higher value. Than look at your scenery and the blurriness should be gone. Now set the value back to your initial value and the bluriness is still gone! For me it looks like that the FS sometimes (when in a saved flight your aircraft is too near to textured objects) has problems with loading textures and just loads the smallest mipmapps of the textures. Anyway this will only happen when you load the scenery direct, not when flying to it. Can you confirm my "solution"?

Thorsten, sim-wings
 
Thanks Thorsten...

I have not noticed the probelm when flying into a new area, only

1) when I open up the scenery at a parking spot on the tarmac, or

2) if I open up on the runway, as soon as I pass an area that has GMAX objects within approx 100m

3) if I switch views to Tower View and the scene contains alot of GMAX objects

So you may have found a solution there...I will go try it this evening (stuck at work right now :cool: )

Thanks again! This group of designers is without a doubt the best informed and helpful group I have found!
 
Well, I went in and maxed all sliders out on my FS and the problem still appears..... :banghead:
 
Hm????
Maybe your problem is caused by too many huge textures? But the scenery looks small. Do you use lots of 1024 x 1024 textures? Did you compress your textures to DXT1 (or DXT3 when containing smooth alpha)?
In my actual project I rezised now all Textures to the minimum I can use and the error is gone.
And: What graphic card and memory are you using? Try to look at your scenery on a different PC. I remember, when I had a Vodoo card (5500 with AA) I had the same strange error with FS2002. But this was definetly a graphic card (driver) error. I exchanged the card and the error was gone.
In conclusion: It must be an error caused by two factors: textures and graphic memory. It seems that FS2004 tries to keep the framerate while loading textures and switches each texture (also the landclass textures) to the minimum mipmap.

Thorsten
 
I believe they are all 512x512 and stored in DXT1 or DXT1 with alpha.

My graphics card is an Nvidia GE FX5700 128Mb card - not top of the line, but not a slouch either...

I will double check the texture sizes and may try reducing the textures to 256x256.

Thanks again!

Todd
:santahat:
 
:banghead: The error is back again at my scenery. I´ll try to solve it by removing the mipmaps from the textures (with adding an blank alpha channel to DXT1 pictures). Hope this will work. :stirthepo

Me again :rolleyes:
Here´s how I solved the problem:
I told you before that the problem at my PC was gone. Than it came back. So i had the opportunity to discover what I had changed that it came back:
I added mipmaps to several DXT1 and DXT3 and 32bit textures. BUT THIS IS WRONG! This caused the scenery system to "switch" to a mode just showing mipmaps everywhere and trieing to load higher mipmaps everywhere at the same time (it will take forever until the bluriness is gone). The solution (for me) was not just to remove the mipmaps (DXT1 without saved mipmaps), you also must add an alpha channel to the DXT1 files (this will surpress the FS2004 mipmap rendering/display). You can simply do this with DXTBMP from M. wright. Until now I had changed about 80% of my textures to DXT1 (or DXT3) without mipmaps and its gone. So you can still use some textures with mipmaps or without alpha, but the majority must be DXT 1 (3) with alpha, than everything works fine. :wizard:

Thorsten
 
OK, so I go into DXTMbp and remove the checkmark for 'Include mipmaps when saving', then create a blank alpha channel (or a black alpha channel mask if needed) and save as DXT1.......

Will try it out :teacher:

Thanks
Todd
 
Well, I finally figured it out! The problem was not with the scenery or the textures at all, the problem was with AI traffic. I had created some AI traffic doing T+G's at the airport. The planes I used were not created for AI use and were just regular planes....I guess the combination of the textures of the scenery and the textures of the AI caused the problem.

If I reduce AI to 0%, or fly online, the problem goes away! :scratchch
 
Good to know that you have figured it out. This is not something you would think of right away. Well done I would say. And something we should remember for the future :D.
