How can I make the map with light without shadows?

foxyfoxfurries

Hey.

I tryed to do it a lot of time but didnt success to put a light without shadow , Now when I mean Light I dont mean to put some PointLight or stuff like this I mean to make light like "the sun" when you dont have wall have a great light that you can put even more with Environment without to much shades.

But when I put walls I cant use this so my question is how can I put the map lighter without the to much shadows , I saw a lot of people make this stuff and it looks more cool when the shadows not come from the PointLights and stuff like that , Thank you very much!

If I understand right, then you want a soft lightning so you don't get defined shadows.

That can be achieved in different ways.

If you have an HDRI, without a defined lightsource, like a sun. Think of an overcast day.

Or you could use some large planes as emitter. A large plane will giver softer shadows, and with emitters from different angles, will clear out the shadows.

Find the ceiling surface and make it Emissive then set the Lumens and/or colour temperature till you get the ambient light you are looking for.

Thanks to both of you Fishtales and felis I dont know how to replay two people but can you explain me how to do it easily? step by step? thanks! :D

How is the scene being lit at the moment?

If we take Fishtales version, then find the ceiling surface - should either be part of the room in the surface tab, or you can use the surface selector tool and click on the ceiling.

When identified, scroll down in the surface tab, till you come to emission. It will default be black. Change it to white. Default color temperature are like a cloudy day.

Then you can adjust the strength of the light (luminance). I would suggest to change luminance units to kcd/m2, and then lower the strengrh tp maybe 100-200 (trial and error).

Richard Haseltine you mean what settings I use?

And about what you told me I dont see anything in the surfaces tab , Maybe I need to click on somthing? 

felis

In the scene tab you have selected a group. You need to expand it and click on an object.

I did it but it change also the map color no? 

felis

Not sure what you mean.

When you select an object in the scene tab, then you can see the corresponding surfaces in the surface tab.

So expanding the group in the scene tab is just for selecting an object. The PA have just groupped a number of object together for practical reasons.

felis

Here is a quick demonstration.

I made a scene with 2 planes, one as floor and one as lightsource, and then added a sphere ti have somehting in the scene.

First image shows the surface tab for emission for the light plane, and the second a render.

You can also use the Surface Selection tool to click on the area you want - that will select both the object and the surface.

Ok thank you both Richard Haseltine but I dont understand , I need to copy some object and then doing it?
Look at the colors it turns so white... I do something wrong for sure here

I really must know how to do it I tierd to use SpotLights and see massive shadows , Thanks again BTW for the help

You have made the whole building a light source :) You only need to make the Ceiling a light source. Put the Emission Colour back to Black and then click on the Ceiling and make it white and then adjust the lumens.

You mean like that ? but also its change the color of the top and not really put so much light , I did it right? dont have any more options? its strange its the first sotware I ever use that dont have some full light even if have walls : / 

Like in there : Bronx Warehouse | Daz 3D
It looks lighter without any changes , + I saw a lot of artist have full building but with lights like dont have any walls how they doing it? : X

felis

Now you need to up the lumens for the ceiling.

I would suggest you change luminance unit to kcd/m2, and then set lumen to 100-200 and see how that works.

Fishtales

Looking at the images in the shop they are either using an HDRI in the Environment Dome or it is set to Sun and Sky to get light shining in through the windows.

So I did it right ? and what you mean about the lumens? about the kcd/m2 I know how to change it but I do it right like you said? I will check it out soon.
And Fishtales about the light i understand but look at this one Military Camp | Daz 3D I have this map as well and saw a lot of people use it , When I put it its so dark really really dark but to other people it looks like a day.

That's my question how to make this maps looks like a day without massive shadows.

Again thanks for the help

If you look at the screenshot I attached higher up, then an emissive surface has:

Emissive color

Emissive Temperature: determines the color of the light in technical term. The default at 6500 K is a blueish, like a cloudy day

Luminance: that is the strenght of the light

Luminance unit: candela per area,1000 cd/m2 = 1 kcd/m2, why I suggested to use kcd/m2, else you have to use luminance values 1000 times higher.

I skipped 2 sided light and emission profile - they are not relevant right here.

 

Ref Military camp: I don't have it. But are you saying tht when you use it, it gets much darker than in the promos?

Technically you could also here turn the ceiling into emissive, but as the walls and the ceiling is the same, it would look weird, if a part of the emissive surface is in the render. For that purpose I would create a plane, scale it and make it emissive.

Fishtales

In the Military Camp they have made the Lights Emissive to give the light not the ceiling, There is probably a slider to turn them off or on. There is also a HDRI in the Environment dome or Sun and Sky to give the light through the windows, that is the light squares you see on the floor.

Thank you so much I try what you say and also try the option with the CM2 factory but it makes my girl eye glow haha , any way it looks more lighter but I only use the CM2 FACTORY also it makes the rendering a lot more time even I have 3080 TI. So I try tomorrow the other thing you say :) but really dont have any option to make it just a day? also not everymap have what you said about the Emissive color? I think I dont understand it right or I just miss something.
Fishtales ok I understand but the question how they do it , thank you a lot for both of you for real!

I also made some picture without the roof when the "sun" comes in look how sharp it looks :)
