    Default Open 3d plan rendering

    Please i need a best rendering and light settings to render an open 3d plan with walls having white diffuse colour and any backgroung colour besides white, so as to not have the background colour not distorting the colour of my rendering or even on white backgroung in a way that i could differentiate the model well from the background

    sounds like you have answered your own question:

    There is no direct light in this image
    HDRI/Environment - Mid Grey GI Light or Monochrome HDRI
    Walls - Whiter than Mid Grey
    Background - White

    i am using the environment light. i need a light settings that will work best for me so i can decide to change my environment diffuse colour and still get a good result. i want a grey backround, and white walls, but it seemed not to be working when using the environment background as light source

    if using the enviroment light just make it a mid grey color and adjust the color value to your liking.

    you can override the background color in the environment settings, or just render the background as an alpha and make the background color as you prefer in photoshop.

    I did that, but while rendering I noticed that changing my environment color to mild grey, also affected the color of the walls, and that's my question. How will I get a different color of environment and different color of wall, because any color I use as environment affects my wall when I use the environment as my light source. So how will I get a good light source and settings that will distinctly separate both environment and walls.

    once you are happy with the intensity of the environment, increase the diffuse value of the wall until its a the white you like.

    My diffuse color of the wall is at white, I even added reflection of mild grey to the wall. See the image I uploaded, as the environment is white, you can hardly differentiate it from the external walls, so it is when its grey. It affects the external walls. I need a grey environment and a white wall. Can I use the environment light to achieve this?, because I have tried and its conflicting or should I introduce an external light source?. If I should, what will the settings look like. That is my challenge

    - adding a reflection to the wall will reflect the environment color. I recommend no reflection on these walls
    - i cannot see any image you have uploaded
    - you can add another light if you wish and just include the wall (the image you have provided looks like there is a rim light added to add to the effect of the walls) you can just include the walls in this light if you wish - just be aware of what extra things you are doing at this point
    - no need to worry about settings

    Example:
    Environment set to mid grey (117,117,177)
    Floor mid grey (117,117,117)
    Walls White (255,255,255)
    Camera EV - 2.0 (adjusted exposure 2 stops to enhance white / compensate for low environment light)
