this basic function is practically in every program out there.
Is it possible that for example my file name is sun.blend that when I render photo fro mthe blend file blender automatically suggest sun.png instead of untitled.png???
Really annoying that this basic function is still missing by default. I haven’t found how to make blender rename render photos automatically so I assume it’s not possible, but perhaps I’m wrong which would be nice.
First, I’d like to challenge your assumption, that this is basic functionality. Blender does have this for .blend files.
Just because we think it’s “easy to do” doesn’t mean it is.
While it’s not really auto-naming, there is a section in the properties editor under the format>output section that allows you to set a file path and file name for renders in advance.
So before you render you can set this to set up to name your renders in advance.
Something like
/desktop/blenderrender/Filename##.png
Will allow you to save several render iterations in the same place and this way blender will know to add 01,02,03 …etc, to the end of your file name.
Not quite as easy as what you are looking for, but it would be the next best available option.
so that would be no like I remembered. I also tested that and still blender don’t named the file anything else than untitled. So this doesn’t work for some reason. I remember it being working becuase I have used it in the past, but since you have write the name there manually I stopped using it since it’s stupid.
And now it seems that it doesn’t even work anymore which is wierd 
no matter where I save the .blend file and then name the path blender doesn’t rename the rendered file when I’m trying to save it nothing else than untitled.
This is just some random thing you thought of. It’s not reasonable to expect every thing you think of to be default functionality. People usually need to name their renders differently from their .blend files.
It’s very easy to make an add-on that would automatically set output path to some path based on the file path or name, however it’s unclear what you mean by:
Do you mean that you set the render output and it doesn’t work?
How do you render? What exact actions do you make? Can you list them step by step so it’s possible to replicate the issue? It’s really hard to understand what the problem is to be honest.
Ok. You would have to enter a filename in the path section for this to work, untitled is a placeholder because a file name was not provided. So there is no auto-naming, Which is why I said that this is not what you are asking for, but rather a work-around that is the next best thing.
This functionality has nothing to do with .blend files, this path would only be used for renders.
I think you misunderstood my comment regarding the numbering. I was trying to say that blender (the program) would only number the files correctly if all the renders in the same sequence are saved to the same folder.
What version of blender are you using? Maybe this doesn’t work in some versions due to a bug or something.
Check out the Loom add-on
it amazes me that I need to download add on instead developers just adding this one simple thing that is part of every other program. no I’m not going to download it, but thanks
expecting as basic function as power button on a computer is not random thought and not unreasonable 
Every software I own use this basic function don’t make it sound complicated and somehow unimaginable hard thing to code in. This is kiddies stuff right here.
doesn’t work and that’s it.
is this the add on???
seems to do alot, but I don’t understand how it renames automatically rendered photo when I save them without me doing extra steps.
It’s not the same as Power button on a computer. It’s not something everybody needs. Why file name? Why not scene?
It’s not. It’s very easy. You missed the part where I asked for more info about the problem, so I can help. I mean if you still want help with this. I will not help against your will
the problem is that blender don’t save the render file like jpeg in same name as the .blend file is automatically when I save it (alt+s)
seems the auto naming when you write the name in the output box works only if you render animations not if you render 1 photo with F12 and then trying to save the file. This is exactly why autonaming is a thing and also why I asked about this feature, but sure lets make us write the file name always manually since why not.
basic function missing there is no good reason not to have it this part of blender is pure joke by now.
No, Blender doesn’t have any of this…
Just have a basic look at other 3D applications and/or renderers.
Check the manual for Maya for instance and see how that is handled there.
Basic batch rendering should be available from within the application, with render tokens for filenames, automatic saving/naming of test (F12) renders, folder setups, being able to render multiple render layers with overrides on camera’s, frame ranges etc. from the same Scene etc.
Blender NOT having any basic batch rendering like this is just a frustration for users coming in from other applications.
And no, Blender’s way of working regarding rendering is a frustrating mess, and still is after I started with 2.8.
Luckily there’s addons to deal with this, but shouldn’t be necessary imho for at least the basic stuff.
My 0.02 cents on this…
I think people are intelligent enough to understad the problem.
But also… there are some solutions.
It doesn’t change the fact that Blender doesn’t have any - by default -
Which is a pain as Blender’s rendering system is so different compared to the other apps out there.
Which also relates to the fact that Blender is file related, not project folder based.
But I shut up now, need more coffee 
Yes… but also wanted “default” may be something different for some people… so someone also has to specify this “default” (even if only once for all future projects).
So when not rendering a animation, nor using a file output node nor rendering by commandline where the filename of any images is specified… then somene has to specify the filename on save… 
( For example by changing the default settngs from /tmp to //renderresult.png as new startup file or even building a template and using a folder for every project… you might even make a filesystem link <projectname>.png → renderresult.png . )
So: no blender doesn’t have this as default… and if it might not met some people idea of default…
Would it be nice to have this… for sure… but also it’s open source… so it’s even possible to contribute something like this…
And… to deal with a file which by default is named untitled.png is by far the easiest problem to solve by any user oneself.
Agree to disagree on this.
It’s a mess, and Ill die on that hill 
Of course… it would be nice to have this…
( Also looking at the changes in the sources according to the replacement of <UDIM> in the filename this seems to be not so hard… have to check where this has to check elsewhere… still haven’t managed to compile the sources by myslef 
…wanted this for… by far too long…)
LOL! RighClick Select…
