VaM 1.x Environment Lighting

[engelkuchkuch]

I feel scenes in VaM is like a dark room with artificial lights at night.

How to make it like daylight with natural light?
I want to create a room, where sunlight shines into it.
I created an assetbundle of a room from daz3d and process it in unity, before imported it to VaM
But I couldnt to achieve a more realistic style or at least close to it.
I used Skybox, HDRI but the light just won't interact with the room. No sunlight beam goes through the window. No global illumination inside the room.
I tried PBRmaterialtranslator, it can interacts, but the color of the room looked washed out.
I didn't know how to use it.
Is there any guide/tutorial that can shine a light on this subject?

And lastly, how to disable backculling?

The Invisible Light in Vam can be set to be a directional light, instead of a point or spot. It doesn't matter where a directional light is located, only it's direction matters. That's how you make a sunlight type effect. In general, I avoid using the Scene Lighting tab, or turn it down. Scene lighting makes things look washed out.

I'm not sure we're getting your question correctly, are you asking for an artistic thing about how to illuminate a dark room with an open window, or is it a technical issue during the conversion from DAZ3D to Unity to VAM where the asset you created has the window blocked for sunlight?

Nevertheless, I agree with SlimerJSpud, 99.9% of the time it's better to disable everything in the Scene Lighting tab and use InvisibleLight atoms to illuminate your scene. You'll take a hit in performance in exchange for much better effect. Make sure to set Shadow Strength to maximum in the directional light for it to interact with your object (example below shadow strength minimum vs maximum).

What I also like to do to simulate light bouncing inside the room is to add a point light where the light hits the wall, like so:

If you don't mind faking it another thing you could try to make a sunlight beam is to use the HPVL plugin. Just make some volume lights without spheres or noise then place them wherever the beams should peak through.
