Hey guys,
I thought it might be a good idea to post my question here in the Archviz section.
I’m looking for some help to setup my lighting correct, the posted scene is a test scene where i try to figure out the correct lighting values for a spot light and his GI influance for the scene.
Basically im looking to use a spot light, just because of the spot it gives me, the only downside so far is, that i’m using a dark brownish floor… Which gives me even with a idirect lighting saturation of 0 or 0.1
a brown oversaturated look. " i have no idea if this is a bug or not, i posted it alreday on answerhub but i got so far no reply" So what im trying is to keep the brignetss from GI for my scene but to get rid of 90 to 95% of the
brownish saturation. RyanB gave me alreday a nice tip to use The lightmass replace node, the only downside from the node is… it’s basically no longer reflecting the real scne “the real floor color” so the GI im getting from the floor is just pure white.
use the ‘lightmass replace’ node but put in a slightly-less-brown colour instead of a white one, that will give you the indirect lighting that you’re after.
Hey thanks for your help…
I alreday tried to use a brighter version of the brown floor color with the “lightmass replace” node but the result is still very over saturated and not accurate…
Before and after pics, and the material network for the GI replace section please
Use alt-5 + alt-6, and post screenshots of both of those too.
It’s definitely in the GI replace, you just need to tweak it to get nice results.
You can use a colorless floor material to build lightmass and after that apply the wood material on it. Also you can tint your walls/ceiling with some color in the diffuse material channel. Don´t forget to use a postprocess volume to control the GI intensity.
First of all thanks for the help guys!
The problem with replacing the brown floor with a white one is that all GI is will be white… I dont like the brownish over satuarted look but some small fragments of the brown color should be in the scene to make it more realisitc right?
I’m uisng a postprocess volume but it gives me no possibilities to reduce the brown saturation… i coud reduce the Diffuse boost but this would reduce the whole GI in my scene…
Keys Alt+5 or Alt+6? never tried this before… i guess it shows me only the GI in my scene ? @Construc I wil post today some screenshots but the material is really simple… The diffuse goes into the “Lightmass replace node” and for the new “GI color” i tried different kinds of white and light brownish colors. The problem by uisng colors is, that they tint the whole area by particular choosen color and the scene looks oversatuarted again by light brown or what ever color.
