• 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.

Blured textures - please help

Hi guys!

I came here again for any advice. I met the problem with blured textures in my scenery probaly month or more ago. I thought that I can find source of the problem but not. So, in scenery I have Ground2K background made by another developer, ground polys in FS2002 style and mostly FS2004 3D objects made in Gmax.

Especially in bad weather condition I have the problem with textutes which doesn't have alpha channel in it. All textures with alpha is Ok. But I cannot convert all textures as I want because some of them ground textures, textures for library objects, crafts and so on.

My question: what happened with them or what I did wrong. My scenery is ready on 90-95%. Now I have to stop it forever. :banghead:

As I might recall somewhere, on some forum awhile ago, someone posted similar problem, and it's solved by erasing mip-maps from texture, and saving as dxt1 (or 3), cannot found that forum anymore, lost in cyberspace :scratchch, so I can only give you advice to try & see what will happen...
 
Thanks for reply.

As far as I remember all my textures are without mip-mapping. I'll double check but I using some library objects with such textures and cannot change them by license. All testures are DXT3 at the moment but I played with different ones.

The only thing which I'm thinking about is export in new 2004 format.
Probably we have go back in 2002 format to eliminate this problem.

Again it happened only with textures without alpha. :scratchch

Any other ideas?
 
Hi,

Are it your own objects that become blurry or also other scener elements that you did not create (I mean the 747 in your screenshot looks like AI or so)?
 
Hi,

I think FS will internally create MIP images when it loads a bitmap with no MIPS. Therefore, creating a bitmap without MIPS does not mean that the high resolution image will allways be used by the sim.

One trick I use is to force colors to 255 so that an entry in the palette is not used. Then I set this entry to fully transparent. It seems that FS is not able to create MIPS when it finds a file like this one.

Regards, Luis

PS, to Arno: I learned you got a job and will start working monday. I would like to wish you the best success on your profession.
 
I am posting as I fixed my blurry problems for my scenery just yesterday. After looking at the forums here I determined the first thing to check would be that I don't have any small textures mapped to large objects in GMAX while there are large textures mapped to large objects in the same scenery. I'm not sure that this helped much, but at least it did reduce the possibility of it being a problem.

Next, I made a backup of my current texture folder. I placed imagetool.exe in my current texture directory and used the command line to recompile my textures as such... imagetool -DXT1 -nomip *.bmp

This just takes all of your current textures and converts them to DXT1 textures with no mip-maps. Of course there is a horrible reduction in quality in previously converted pictures, and if you have alpha channels they will be messed up. But this step is only used to see if you can correct your problem by using DXT1 and no mip-maps as a standard.

Once you have run imagetool from the command line as above you will have a bunch of .mip files in your folder. Your previous files need to be erased and these files need to be made into your .bmp files. Once you've erased your bmp's use this in the command line to rename the files in one batch step (credit to someone in a previous post for giving this command)... ren *.mip *.bmp

I went to my scenery and all of my blurries were gone. I also tried the same thing with... imagetool -DXT1 *.bmp

This by default creates mip-maps for all of the textures. The problem did not return. Personally though, I think I will go without the mipmaps as there are some strange bits about the absolute highest quality not showing up all the time (which I know can be solved, but I haven't the time at the moment).

Also, make sure to check your AI traffic. Turn it all the way off and see if you get blurries. Some AI aircraft have been reported to cause this problem.

Anyways, from my point of view the solution is...

1) Check and make sure that the blurry problem is not caused by something as simple as AI traffic.

2) Make sure either all of your textures have mipmaps or dont have mipmaps.

Maybe others can add to my list, but it is a start and is what worked for me.

Good luck!

Click to expand...

I think you are refering to another problem I have mentioned before here.

Sometimes the correct mipmap is not selected on your objects. That is also way I asked if Scorpio had this problem with his own objects or with other objects. This is because if you use a texture on multiple places on your object, GMax will not always insert the correct scale in your texture list. This causes FS to select the wrong mipmap. To solve this you would have to correct the scale in the texture list.
 
Thanks for replies!

I posted reply before but it disappeared due to server crash.
After that I had problems with ISP.

So, back to the problem...
I have blured textures for everything. The only exception is testure with alpha channel as my ARP near by default B747. But B747 is blurred and all other thing as well.

What should I try apart separating textures for different objects? And how I can get the same scale for different objects?
 
Arno, could you describe that thing a little more?

Just since yesterday, my scenery is absolutely blurred - taht means alls textures in FS, from the default aircraft to scenery textures.
Maybe it has to do with the runway-markings. I use a white stripe for both lateral and longitudal borderlines of the runway, which means of course, that the same part of the texture ist once very stretched and then in original scale.

Do I have to use different textures for those markings?
 
Hi,

The problem I am refering to only affects the object the texture is applied to, not everything else in FS. So I don't think it is the same problem.
 
Yes, I tried it another way and the blurring still appears. But after reloading the textures within FS once or twice it's OK.
Could be that I should use LODs for my objects. I have the feeling, it's just my system that's not good enough. :o
 
Hi Thorsten,

There is another thread about this blurry problem as well. But we never found a real cause for the problem. And when something was found it did not always help on other systems as well, so I am afraid there is no simple solution for this one :(.
 
I still think it's an object-problem. When I reload the textures looking away from my objects, evrything is OK. The blurring appears when I'm turning the view to the runway (or objects near it). :confused:

After two or three reloads of the textures the problem disappears and only comes back if I change the time of year. :confused:
 
Hi Thorsten,

Can you maybe mail me your scenery files? I would love to take a look at them to see if I can see the problem as well. Until now I never managed to reproduce problems like this :).
 
Got it. Will probably be during the weekend before I can have a proper look at it.
 
Very old thread here but there is no answer to the problem?

I had the same problem in my last scenery. The bluring only came up when I flew a bit away from the airport, then turned back or used the outside view and turned around the plane. Soon as my airport objects came into view on the screen, the whole scenery blured. It lasts as long as you turn your view away from the airport and push the alt button once. The texture reloads and everything is clear again. In this last scenery I found out it was the tower with it's transparecies. I rebuild it from scratch and everything was fine. I thought maybe the file was somwehow corrupted but now, in my new scenery I just have exactly the same problem.
As long as I am on the airport everything is fine. Fly a few miles away and look back... bang! Everything blured.
What could that be?
It has nothing to do with mip maps. I guess it is the transparecies on some objects.
 
One of the textures in the scene has no mip maps thast's why it's bombing out. I have had this problem and lost a lot of hair over it before I found out the cause. It is a mip map issue.
 
Really, that solved the problem. Unbelievable! I will include you in my next prayer, whenever that will be...:rolleyes:

I tried the whole day and I tracked it down to 3 buildings in the scenery that caused the problem. Each of them alone in the scenery would cause it.
The funny thing is, there are other buildings in this scenery that use the same textures but don't cause a problem.

Anyway, I gave every single texture now some mips and now it works!:idea:

Thanks once again.:)
 
Hi all,


I have a similar problem. I have a quiet complex object using 5 different textures.

It takes a lot of time till he gets clear the textures, or you have to move very very close. All the textures applied on this objects have mipmap. So I do not understand. Any idea?
