Below are a series of lighting tests I did. I applied a some very quick shaders to the trees, floor etc. just to see how the light works with the colours, even though I will add UVs later. I chose an ambient light because it is the strongest light and as the light source is the sun, it is the suitable chose - I made it give a yellow light because of this. I played around with the intensity and I didn't go over 1.00. I think from 0.8 to 1.00 is the range I'll go for because it is neither too dark or too bright. I will need to do some more lighting tests to see which level of intensity I should choose.
