My problem is:
a) short story:
while using Paper Tiger's Precision & Revolution HDRI Lighting, my viewport is almost entirely dark (can't differ character on screen from a chair) when I'm using DrawStyle>Texture Shaded
b) long story:
That scene I'm talking about is something I was working on with different lights and camera (now I use Paper's Tiger...+ X-Ray camera) that was: no HDRI, only scene lights in environment mode, on scene only distant/spot lights. My main light was distant light, now all those old lights are set to be off (visible in render; thought I didn't deleted them completely from the scene). When I for example set distant light to be on, I can see my scene in viewport with texture shaded clearly.
When I make new scene, load my saved Paper's Tiger... rendering setting, use X-Ray camera, all is ok, I can see texture shaded normally. As for rendering (or when I use DrawStyle>NVIDIA Iray), viewport area of aspect ratio isn't black screen.
What can I do to be able to see what I have in viewport with texture shaded in my old scene while using Paper's Tiger... (so it wouldn't be black screen as in attached image)?
Here's how my viewport look like when I have no distant light on:
