• 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.

Big texture problem ( blurred)

Hello guys
We have ran up to a very serious problem with ALL textures in FS. After some time they go blurred, especially when rotating around the aircraft fastly with POV hat or active camera, then the textures like can't reload and won't go to normal any more. Reloading them won't help, only restart to FS.

At first they were 1024*1024 32bit, then I resized them to 512 , then to 8 bit, after that tried with DXT1to everything, then 512 mipmaps DXT1. Still nothing. Then i removed the custom made ground, though maybe it is a ressource eater, that didn't help.
It is driving me crazy. The total size of the texture folder is around 30 megabytes with night textures. Compared with OSS Gatwick it is not much at all, 512 size should be ok too. It appears at all 3 designers computers. 2 of them have 1024 RAM and one has 512, so the problem can't be there. I also looked at RAM usage, and it is completely normal.

By removing all buildings with those "bigger" textures the blurred thing goes away. It won´t appear with ground.

I have these things in my mind:
*gmax models are causing this
*placement of the textures in the file ( see picture below, I attatched 2 bmp-s into 1 pic for the shot)
*photoreal ground in the TMA somehow causing it

ALL suggestions, ideas and everything that could help us to solve this problem welcome.

Hi,

What happens if your textures don't have MIPs?

Ensure that "Max Global Texture Size" is set to MAXIMUM under Display settings -> Hardware tab in FS. :)

Best regards,
Robin.
 
Still the same. I have tried EVERYTHING with the textures. With or without mimpmapps, DXT1 DXT3, 16bit, 32bit Tryed out with the global max, no changes.
 
I had the exact same problem a few weeks ago. For me it had nothing to do with textures. It was a corrupt object I had installed.

I began by removing one bgl file at a time until I discovered which bgl file was casusing the problem. For me it was a library bgl file I had made, one of the objects was causing the problem. I then had to remove the objects one by one from the library until I discovered the problem mdl.

I then attempted to fix this object in gmax. I had to delete some parts and recreate them.

This fixed the blurries for me.

thanks
Steve
 
Thanks Steve
Will try it out tomorrow and most certainly will inform you about the results
Until then: HELP!
 
I've noticed that in areas where there is a lot of scenery, sometimes textures can be slow to load, and sometimes a lower level mipmap might be displayed. This will not only affect your building textures, but also the ground textures like you see in your screenshots. My impression is that this has more to do with your own system, specifically the amount of memory you have installed. One way to check is to verify the results with someone else's system. You can try reducing the affect by making your textures smaller, or lowering the scenery settings in FS. I notice big differences between my 2 computers, one with 512MB, and the other with 1.5GB of ram.

Hello
Well the scenery has been tested on 5 different PC-s from AMD 1.6 GHZ ending with P4 3ghz, with the same results ( blurr )
I tried with both 512 and 1024 with the same texture problem occuring.
 
Ive had it before, also with my own textures. Apparently in your settings, mipmap quality has to be max as well, along with global texture size. I dunno if thats already said.
 
If it happens on only a few objects, it could be that the texture size is set wrong in their texture list.

But if it happens to all textures, then it is something else. One of the FS devellopers made a post about this on his blog (can't remember the link at the moment), but the basic explaination was that if FS can not process and load all textures at the given moment, it is switching to the lower resolution (and thus blury). So this depends on your PC and on the complexity of the scenery that you use.
 
I have 2 folders, in one i have buildings and stuff created by myself. This one creates problems. It contains 52 BGLs + the texture folder is 25 megabytes with 256 and 512 textures in dxt1 formats and with mipmaps. It can´t be impossible to load . Atleast i hope so. And it seems it doesn´t depend on the computer, since I have tried it on low-end to high-end PC-s
Any ideas what to do next?

Hi,

I've had this problem with every scenery I've made. But with 2 diffeent causes.

The last release I did, was four RAF airfields in one package, everytime I flew near one of them everything when blurry, It took me ages to find the problem, I thought at first it was maybe a problem with one of the models, so checked them all (took forever), I then removed all the textures from the Texture folder (for the models I checked) and everything was fine, no blurring. So it must be a texture, I then put all the textures back and instantly the blurriness returned so....I removed them again and started to replace them 2 at a time, To cut a long story short.

I found one texture 256x1024 that didnt have mipmaps, I created mipmaps in image tool and that was that, blurriness gone forever.

This also happened with another scenery, funny enough with the same texture.

But in a Scottish airport I did, I had the same blurry problem but with a different cause, After checking all the models I tracked it down to the Tower, but the texture had mipmaps, so I removed the textures completely, the blurring still happened, so I removed the model, blurring stopped. This time it was the actual model that was causing the blurring effect.

I rebuilt the tower using the same texture and it worked fine?? :confused:

So theres my two different causes and how I solved them, although each time it happens and I have to check everything single thing, I can feel life slowing slipping away :eek: fingers crossed, in my newest project, it hasnt happened..........yet!!!! :wave:

Stevo ;)
 
Also in my RAF package, when the texture didnt have the mipmaps, in fs the textures took about 3-4 seconds to load at which point they went blurry. once I added mips they loaded instantly.

Stevo ;)
 
Hello Stevo
FS is a strange thing. I had all textures with mipmapps. Then i took the backup ones i created before mipmapping and mipmapped them. Besides that i created new BGLs
No blurries at the moment. But i also forgot to ask some things.
How to avoid those ugly black lines on ground ( pic-s below)
The textures are 512*512 and DXT1 It has 13 separate textures attatched onto plain objects in gmax.
We didn't have those lines with 1024*1024
Could it be a FS bug because I haven't seen any grounds created with 512 textures.

Hello

I work on the same project as sk699. We have now solved both of the problems we had. Thanks for all the help :)

Adding mipmaps to some textures seemed to solve the blurriness problem.

Regarding black lines between ground tiles, FS seems to render a black line on the edges of textures. What confused us was that there were no lines when using 1024x1024 textures but they appeared with 512x512 and using the same ground BGL file.

To remove the lines, I made similiar trick as in the thread that Arno referred. Only difference is that I used UWM map (as described in http://www.scenerydesign.org/forum/showthread.php?t=1315) and increased the length and width of the map so edges of textures are not visible. This should be a little easier that moving unwrap lines on each texture.
