Default Rendered *.wav sounds different ...

... to that what I hear direct when playing the mix in reaper.
This is the first time, so, I must have done something I don't know.
Some plugins in the mastertrack, but that shouldn't matter.
Any ideas where to look?

Maybe the panlaw on the playback track isn't set to 0? It could also be just your ears playing tricks on you, maybe you can a/b in realtime: move the whole project in a folder and put the fx from the masterbuss there. Then load the rendered wav on a separate track. If you invert the wav they should cancel each other out, if they don't it could help pinpoint where the problem is

Are you re-importing the mix in to Reaper to test the playback?
If not how are you playing it?
Have you got any monitor fx loaded in Reaper?

Yes. I always have a track that I call 'rendered' where I put files to compare. This track is not routed to the master but direct to the hardware output I use.
Listening here is the same as if I play that rendered file with an external player (foobar).
Listening here and switching mute vs. solo show the effect described.

The track pan law still affects that and can make the file sound quieter.

Even if it is muted vs. soloed? And, it is the same if I compare from the external player.
And, it is not only volume, but the sound of the rendered file is more dull than the mix.
I will check all my fx busses if there is a mistake in routing.

I think I have found the culprit ... and that is a bit strange:
as last fx in the master track I am using a limiter from tracktion (DAW essentials).
If I disable that limiter, direct listening to the mix is the same as the rendered version, if I enable I get the described effect.
Mmmhhh.

Meanwhile I have rendered without using that limiter, imported the wav file to (tracktion) waveform, pulled that limiter as only fx to the track, exported now as 'limited' wav file and the result is as expected.
So I think, that reaper and this limiter vst are not compatible.

Are the company support active on that forum?...I don't see much evidence of it though didn't check too far back.

Official support would be here:

try null testing.. put the rendered track in the mix, but, either click the phase for the track, or click the phase for all the stems.. if there is difference you will hear it. (If there is complete silence, then they are the same.)

No, there is a problem with the PlugIn. I have made a video to describe (and send it to tracktion support):
https://youtu.be/cKDfmvWvxRo
1. audio-part: mix of the song in reaper
2. audio-part: the rendered file that I have placed in a seperate track in reaper (is not routed to the mastertrack but direct to the hardware output!) So I can easily toggle between both
3. audio-part: toggle between both
4. audio-part: reaper mix with disabled mastermix vs. 2. audio-part

You can also try an online render (File -> Render -> change "Full-speed Offline" to "Online Render") to see if that is a usable workaround.

Some news:
The problem seem to be related to downsampling.
My wav files are with 48 Khz and when rendering I use the 44.1 Khz option.
Has someone problems with that?

Tht's true, it's related to downgrading from 48khx to 44.1lkhx.
If you import a media file recordered at 48khz in a project sampled at 44.1khz and then render the project you have this issue.
The solution is to upgrade the entire project to 48khz and the render the file otherwise downgrade before the media file from 48 to 44.1 (same sample of the project) and then render.

To summarize: all media file must have the same sample frequency of the project.

Hope this help,
ric

EDIT: the above explanation is not correct. The difference in sound volume is not releted to downgradinf from 48 to 44.1, but instead from a diffent value setup of Windows mixer (not set correctly to 100%) vs volume played into Reaper that play with ASIO driver in my specific case. Hope this helps.
