Texture map rendering dark

I'm trying to set up some Lightworks materials for a project and I'm having trouble getting the stone colour the way I want it. Could anyone suggest what I need to do the material settings to get it to look more like sandstone and less like granite

I've attached a rendering done in ArchiCAD of the building looking all gloomy and I've posted the same texture rendered in Strata CX plus the original texture map (which maybe of use to others btw)

TIA

Well I'm a dunder heid When I went back and checked all my settings for Photo Rendering the Sun was set to only 70% when I cranked it up to 100% everything got better in fact I had to turn down the Image Brightness setting.

I also took a closer look at the Lightworks sun settings by deactivating the Essential only button.

Shadow Quality when I messed about with this you can actually cause the shadows to break up and become black dots which doesn't look good at all. So take it easy with that one.

In there as well is a setting for Colour Tempature now this one doesn't give you any indication of what the end result so I tried a few renders see attached image.

Color "temperature," as any high school science student learned but never had any reason to remember unless they heat theoretical black masses to various temperatures to watch them glow for a living, or render with LightWorks, is the color emitted by a theoretical black mass when heated relative to absolute degrees [Kelvin]

Noon daylite in Upper Hutt New Zealand where the whitest light in the world is found should be 5000 degrees Kelvin.
Light bulbs range from 1900 [orange] upward.

You'll discover that adjusting both the ArchiCAD Sun color and LightWorks Color Temperature makes a hybrid color. Keep ArchiCAD color white if using LightWorks.

Now you see why the book is taking so long. Like peeling an onion, this.

If anyone around here did some at least half serious non digital photography, they would know that light differ in color temperature.

The daylight has many temperatures, the neon lights have another, incandescent bulbs the third ... that is why you have different color temperature 35mm and other films to use. If you use daylight film, sensitized to blueish daylight, the neon-lit scenes will be green, and the bulb-lit scenes will be more or less yellow.

So it is not unimportant ... to know

i did some research on this "colour temperature", if your interested, check out this website at "http://members.shaw.ca/jimht03/light.html"
cheers,,


I couldn't get your url to work. So I had a look for some info myself and came up with this. http://www.aeimages.com/learn/color-correction.html

It has a simple table listing in Kelvin various lighting scenarios and what the colour temperature would be for each.

Thing I'm not sure about is what units is the Lightworks Colour Temp setting using is it Kelvin? The slider gives a range of 0 to 50,000 bushels, banana skins who knows?

Coconut peels stacked into oysters, methinks ... 😉

It is Kelvin
