hi guys, this is a screenshot of my try-outs for getting the lighting good in this scene, but unfortunately you can all see these weird light spots on the walls, i don't know where they came from and i don't know how to get rid of them.
Any advice is much appreciated, thanks!

Is the SU Podium or ProWalker?  I have had some strange spots like that with ProWalker.

My guess would be the christmas tree lights are being reflected indirectly all over the room.  Did this come from Browser?  If so, which one?

This is a sampling error caused by the default preset. Use the QMC or high presets.

I tried QMC and ended dissapointed by the result.
I'll have to switch to Vray for Sketchup.

That's not good, I'm not sure why that didn't work.

Did you try the high preset?

You might upload the particular model to us so we can take a look. 
If you don't want to make the file public upload it here -
https://suplugins.com/podium/support.php

Can you look in Options / Envirnoment and see if Caustic is on.

OK. So I think the issue is that Caustics are on.  Here is my experiment with the same Christmas tree.
large-kitchen-show-room3 2020-01-02 10355000000.png  Without Caustic on....(don't mind the door frame, a little to much blur on the metal material).

large-kitchen-show-room3 2020-01-02 11090500000.png  Caustics on.  So turn Caustic off.

I think vray doesn't mean you'll get your extraordinary rendering. In order to get a very good rendering, very good scenes need very good composition. A powerful single core processor. Powerful multi-core processor. Good graphics card. Clean models. Nice texture. Once you've created them, you can import them from the 3ds max and corono rendering engine instead of the sketchup vray. You can save your scene in sketchup 8 format and open it in 3ds max. The Corona rendering engine can save and render textures of the entire scene. It's just a waste of time for me. 🙂

Tony, the thing you will find with Vray, is that as good as it is, it's much, much more complicated than Podium.
Because of this, what people often find, is that their renders can be worse, because they have configured all sorts of settings they don't understand.
You didn't understand what caustics are, yet you turned it on and it not only ruined your renders, but increased your render time. It's one of the few checkboxes in Podium that can ruin your renders.

There's a lot more of that sort of thing in Vray 😉

It won't magically make your renders better. In fact it won't make this scene much better. Your texture on the beams is running in the wrong direction, your furniture has too much reflection, and the scale of the texture on the table is too big. There isn't much detail in the scene either and the furniture is very crude.

Ottoman's point is absolutely right. You need to set your models up properly to get good results. 

Start simple, pay attention to your detail and your textures, then don't try too hard with the lighting.

We can help you to improve!

you are absolutely right, but i like the UI and the interactive render much more than in SUPodium.
Ok it is a steeper learning curve, but i feel comfortable in the environment.
A great feature is the Render Farm from Vray, no more waiting for my renders and no need for investing in a fast graphics card.
Anyway, i did buy Su Podium and i will continue to follow it's progress and once it satisfies my needs, i will probably return to it because i like the idea of simplicity.
