White wall texture

fuzzytnth3 — Thu, 11 May 2023 10:51:39 GMT

From Dwight's book he says....

"There's just too much whiteness in the world, especially when there is no such thing as "white." Highly reflective surfaces immediately glare out and can't express the character of a scene. This is why texture should be applied to all neutral surfaces, surface reflectance and illustrations should combinations of tinted color-it simply makes surfaces more interesting than white light does."

While the above is good advice, I was wondering what folks had managed to put together as their favourite white wall texture for interior views?

I've attached an attribute file which is what we use as a starting point for a matt emulsion.

You've made this cold grey based in my nominal roughness surface.
I suggest that the ideal neutral surface is achieved if you reduce blue from 234 to 226 for a slightly warm tint.

Could you give me an understanding of how an attribute file is used? How is it created and how to load it in a new material? Foe example the download of this file is named AMA White Emulsion Matt.aat,when you make a new material in Internal engine and find the material to load it searches and tries to load it but is not succesfull. Is there a special way to load this file to a new material? Then if you want to change the color or texture say to create a stressed wall how do you combine the the properties of this wall surface with a texture?

AAT Attribute files are stored attributes of many properties.
You employ the Attribute Manager to append new attributes to an existing file.

Thank you.

As for the rest of your question, that takes a small essay to explain.

There happens to be a chapter in my book that clarifies how to work with textures and shaders in LightWorks that is of some applicability with the Infernal Engine.

will check it out.
thanks again

Use the Attribute Manager command to import the material settings. The material I've made is intended to be used with the Lightworks rendering engine not the Internal REngine btw.

To select which engine ArchiCAD will use to Photorender adjust the Photorendering settings in the Creative Imaging command.

Yes I have now realized that you need to load it as an attribute in Attribute Manager thanks to Dwight's advice and not as a materials image. You mentioned in your post that you use this material as a base Does that imply that you can change colors as well as bring in textures in the Infernal Engine also and maintain the great qualities of the original material? I would love to see an example of how you have used this material in another manner.

Internal Engine only uses textures.
To take ANYTHING from LightWorks shaders means capturing an image from a rendered wall, ensuring that it is sized correctly.

I am not sure if I understand what you mean. Could you please expound on that thought?

Shaders can be mathematically generated - no visible texture until rendered.
Lightworks can use shaders, alone or in combination with textures.

Textures are images. The internal engine uses textures.

The only way to get a shader-like image into the internal engine is to somehow make a rendered image of it and then capture that image, using it to make the internal engine texture.

We do this by rendering a softly lit wall - say 1mx1m for easy sizing - and taking a screenshot of it.n NOw you have a texture for the internal engine.

Viola!!! Bassoon!

Perfect. I got it. Now to your reply that Lightworks can use a shader in combination with a texture. Do you choose the shader and load the image to this shader? In this case would you duplicate the .aat imported material and in LW choose a texture image to combine with this material without affecting any of the qualities of this material?
BTW I want to thank( fuzzytnth3) for his contribution of this material Good work!

Sit down and study how LightWorks makes a Surface and you will have your answer.

You'll see that most shader classes have a choice of an image file.

Yes, I will do that.
Thank you
