• 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.

Texture crispness

..... or rather the LACK of that is haunting me now when texturing my objects.
I have built objects in Sketchup, according to real life measurements. They fit on my monitor of course, but maybe they are HUGE !?
In any case, when I paint my 2048 x 2048 texture tile onto it, it turns out the texture is tiny and needs to be stretched A LOT to make it fit........ and then it is extremely fuzzy of course because of the magnification applied.

So HOW do I get sharp textures on my models !!???? Do I need to reduce the 3D model size before starting the painting? Is there a trick I missed !?

HELP !!!! :-)

The size of the model makes no difference, as long as it is a reasonable size in FS. Are you using the entire 2048 width across that single portion on the left and that is still blurry? If so, then you have to divide up your object into even smaller size chunks and texture each portion separately.

Have you looked at your model in FS? It might look better there.
 
Thanks for your reply Tom appreciate it!
I use a 2048x2048 tile..... you can see 'them' in the middle of the model. When I use it to 'paint' it turns out that small (and gives me 100's of little tiles, one of which I have to drag to size). That's what I did with the rearmost part of the craft..... that is part of the tile stretched to fit the model.
Because of my (bad?) model I have the side divvies up in 4 parts, but the paint tile covers the entire length.

I already experimented by reducing the model size .... same effect. Maybe my original isn't 'sharp' enough? I use a png file as original and have 'paintbrushed' the colours and rust streaks onto it. I'll try a photo instead to see if that makes any difference.
 
Hi Francois,

I usually take a more mathematical approach (I know that is not everybody's cup of tea :)).

So for example if your ship is 100 meter long, the 2048 pixels texture applied along the full length would give you a resolution of around 1 pixel per 5 cm.

Then it depends on how close you get to the object. For many objects 5 cm would be fine, but for an airport you get very close to you might want a higher resolution. In that case you would have to do what Tom said. Just apply two strips of 2048 pixels width to your model. One part for the front half and one part for the back half.

The size of your model would affect the resolution you get. But only if you don't scale it up again in FS. So if you made it in real size, then making it smaller won't really help.

I usually try to give myself an aim before I start texturing what kind of resolution I want to use. Then I can design my textures based on that.
 
Hi Arno, thanks !! That makes sense. I was focusing on having everything on just ONE 2048x2048 tile, but I guess I can add more, or put 2 halves atop each other.... I am just paranoid for performance I guess :-)
 
It's a very good habit to try to fit everything on one texture sheet. But if it just doesn't work for some object and that object is very important for the scenery, you can always sacrifice another drawcalll of course :)
 
Since the area you are texturing is much wider than it is tall, you should indeed be able to put 2 or 3 strips on the same square texture.

In the Sketchup Material Editor you can define the texture size, I think the default is 2 feet x 2 feet.

Increase that to a more realistic size and you won't have to stretch it so much.

Hope this helps.

cheers,
Lane

Didn't know that..... will have a look again. Thanks Lane !
