Hi,
A few weeks ago I went back to Blender with version 2.8 which is a revolution.
On the other hand I have export problems with and I don’t understand where my problem comes from, I have some supposition about the new EEVEE rendering system but I don’t know enough to confirm it.
Basically my problem is when I export files whether it’s FBX or OBJ the product rendering has nothing to do with the rendering I have in Blender, yet the textures are well exported ( at least normally).
Here is an example of one of the different tests I was able to do in comparison with the rendering on Blender.
(This is one of the best results I’ve ever had and I just realized that I don’t have a screen of really buggy versions --’)

For the export parameters I mainly followed the advice I could see on reddit

)
Last but not least, the most blocking trick because the design can be improved later if necessary.
This is the import on Mixamo which with any version of the export I could do I always have this error message.
“Sorry, unable to map your existing skeleton”
Thank you in advance and let me know if you need any further information.
