Light is coming from wrong direction...

Hello, I have posed a figure and then placed sunlight which I can change direction and altitude, so I rotated it at an angle that hits the figure from the front and a bit sideways, but when I see the final render the light is coming from the back, which it totally wrong... I deleted the light and placed it again, I checked that there are no other lights, and I switched off the 'Draw Dome' setting but still useless....

I assume that you checked the light settings at the top of the enviorment settings portion of your render settings tab and confirmed that it's set to sun/sky only? If so, I'd check to see if there's an object with emmissive llight properties somewhere in the scene, or something that's highly reflective and possibly kicking up and doubling the exposure on the reverse side.
Yes, it's set to Sun/Sky only.... When you say 'an object' do you mean even part of the characters' armor? And if so, do I need to go to the Parameters and check there for the emissive light or something highly reflective? And then lower the settings down?
These days almost anything can be emmisive. I'd just turn off all the lights and try a render to see if anything happens... if there's nothing, it's not an emissive issue. If your character's wearing armor then it's very possible that what you're dealing with is a suncat... those bright reflections that you get when certain surfaces refect light. However, if you move the figure or the sun and the glare doesn't change, it's probably something in the environment like a hidden mesh light. Oh, and you are rendering in a regular camera and not the perspective camera,right? All kinds of funky things can happen when you do that.
Yes, it's a regular camera. So how do you find this hidden mesh light so that I can delete it?
If you tried rendering with different or no lights and something is still being illuminated, I'd just pop a couple of random primatives in there and see if you can triangulate it, then swtich through a couple of the mesh modes while looking in the that general direction. To be bright enough to be affecting the sun it's got to be a really bright item, assuming that that's even what it is.
If you are using the light as a sun then you will need to set the dome to Dome and Scene or Scene Only or the light wont be used in the render. Even with Draw Dome set to Off the light is still used from the Dome.
As Fishtales said, even with Draw Dome turned off, if your lighting is dome&scene, then the light from the dome is still used, no matter where you place some sun prop.
If it's a relatively small scene, then I'd suggest rotating the scene. You can also y-rotate the dome (it's a bit further down in the render settings), but that might require some going back and forth to get it exactly where you want
@stephangrixti "placed sunlight which I can change direction and altitude, . . . . . it's set to Sun/Sky only"
Sun-Sky works by setting Lat, Lon, Date, Time, and UTC offset. Is that what you mean by "placed sunlight"
Surround everything by a cube just big enough, put a camera inside it, see what you get, or not.
Yes, it's a regular camera. So how do you find this hidden mesh light so that I can delete it?
No no, what I mean is that the light is a sunrise, it's one of a set of sunlights I purchased from Daz3d
Which set of lights is it? I can tell more from that than almost anything else you can tell me.
As for how to turn a hidden mesh light off, the easiet way is to delete it, and how to do that really depends on where it is and how it's stuck in the scene.... it could be on a sky dome, a spot, parented to the camera or a prop, There's a tool by V3DIgitimes that can usually find hidden light sources https://www.daz3d.com/iray-light-manager-pro ; Am I correct in assuming that you actually did this https://helpdaz.zendesk.com/hc/en-us/articles/207913296-Removing-Default-Lighting-in-Daz-Studio- and you're still seeing the light that you don't want?
Ah, here may be your problem. You say you bought the sunlights from the shop, but that doesn't have anything to do with the environment. If you set the Environment Mode to Sun-Sky Only, it'll generate it's own sun. You need to do as Fishtales say and select Scene only. That way you don't have any light coming from "outside" sources such as the environment, and only have the lights you place yourself.
I have set the render setting to 'Scene Only' but now, the character, horse and prop are all pitch black, there is no texture in the render.... Why is this?
Can you at least tell us what light set you bought so we can have a look at it.
In Daz3D the light package is called 'IG Iray Dawn to Dusk', I think it's this one: https://www.daz3d.com/ig-iray-dawn-to-dusk
First off, are you facing the right direction for what you want?
The default view in Studio is North so sunrise is on the right of the screen. To get sunrise on the left, as if you were facing South, you either need to turn the Dome 180 or the camera you are viewing through. That also goes for any figures you have in the scene as they all load facing South, which would be towards the default camera/perspective view.
Looking at the set, I don't have it, there are various settings for getting the sun in the right position and also render settings to match. You will have to have Sun and Sky set for the dome or the settings wont work, as far as I can deduce from the video and description.
