Printed appearance of elevations

Anonymous — Tue, 23 May 2023 01:15:03 GMT

Hello,

Can anyone tell me....what determines the printed colour of wall and other surfaces of Archicad materials. I have my elevations set up so that under Model Effects, Element's Own Material Colours are displayed. I am using Surface whitewash or a variation of same as the wall material. This appears in the printed elevations as a mid grey tone. This is very muddy looking and I would like to change this if possible. How can I control the colored appearance of surfaces in printed elevations without messing up my 3D model materials? Any help appreciated.

Thanks in advance

The elevation material color is based on the Interior Engine preview color of the material.

Still doesn't explain why the white material shows up as grey.

please post:

--an image of the offending view
-- your internal engine material setting.
-- your sun position in the elevation setting dialog

Elevation from the S/E window?

Rendering?

OpenGL 3D view?

What EXACTLY are you printing or trying to print?\

A screenshot would help a lot ...

Since our colleague is not forthcoming, I can only suppose that it is an analytical view where the (no such thing as) white is not directly lit.

Hi again,

Sorry for taking so long to get back....okay here is one typical image....the one thing I have altered is the settings in Vectorial Sun Shadows to Custom which has brightened the image up to some degree...

And here are the Internal Engine settings.....

I see white in the view, (Red arrow) so it can't be that the rendering is generally too dark. What material is that? Put the values that material has on the whitewash and see. I think that whatever rendering method you are using, that there's not enough light directly falling on the surface to satisfy you as to its whiteness.

You can artificially increase the reflectance of the walls to overcome the shading, but this looks pretty good to me.

Where the flaw is: your expectation that something said to be white is really light grey, except in perpendicular light, because it is not highly reflective.

Hi and Thanks dwight,

What you are are looking at there is an open space under an external stair landing.

I take your point re: expectations of whiteness. The appearance certainly has improved since employing Custom Vectorial Sun Shadows. Though this is not an accurate representation of the actual building orientation, I think for graphical purposes it is fine.

Thanks again

it's not - it's a nasty bug. since internal engine generated, coloured elevations are just that: coloured, then no-such-thing-as-white is a valid 'colour' to use. rendering/illustration and the 3D window, dwight, are a totally different kettle of fish from this . . .

all other coloured materials come out the colour they are assigned in the materials settings. their tone is adjusted to compensate for shadow or fall-off around a curve but their un-shaded perpendicular surface to the elevation viewpoint is the colour they are assigned. except white, which comes out a dirty, grubby grey regardless of sun azimuth or altitude.

i sent a bug e-mail a few months ago about this and i saw recently that link has reported it again. the reply i received was that it had "super high 'future release' status". i've been meaning to give it some follow-up and add some weight to link's report: thanks for the reminder

Identify the color in PM and make it white

no can do adalabert: it's a shaded elevation and therefore an RGB colour generated by the internal engine . . .

As I recall they all came out a little duller no matter what the color, although I couldn't see a consistent pattern when comparing them in Photoshop. And since the Vectorial Sun Shadows were turned off, I didn't know what was causing it.

I am sure our good friends at Graphisoft are on top of it and everything will be fixed next time!
