Wall painting - fill effects??

Is it possible to color wall as in picture?

depends on how you're thinking of doing it:

if you are talking about assigning a gradient fill to a material and having it automatically show on the wall (or whatever element is using that material) then no.

if you are talking simply about colouring the wall in a section or elevation window then yes - simply use the gradient fill and draw it in over the top of the model - note that it won't update should the wall change though . . .

If you want a gradient wall in a RENDERING, you could make a material that used a large graduated color image and anchor it to one corner of the wall using the align texture tool.

You might also simply use the PICTURE object, placing it against the wall and sizing it to match, using the graduated color image as if it were a picture.

@ ~/archiben OK, I'll try with gradient fill (if I find the way xD)

@ Dwight That's good idea but I want to color curved wall... I'll try somehow hh 🙂

SO here it is.

And with an alpha channel for transparency

Thank you Dwight, now I know it's possible but probably need to set the options - don't have any results.

I'll post preview when I make it, tnx 🙂

I can't make 3d fill, just could create in floor plan and sections... (2D)

Dwight... Can you send me a short procedure for that wall you sent... Please

The same as for any texture map in a material.

The Align Texture tool anchors the origin of the texture.

You must save first the gradient fill as JPEG to put ii in material setting.

As a general rule, JPEG is the worst possible file format to use because JPEG files contain artifacts that are emphasized in rendering, especially when you are trying to create a smooth gradient with a gigantic file.

Thanks for the tip.
Than what kind of format for gradient (or such vector for rendering) do you want to suggest? TIFF?

Re: Wall painting - fill effects??

Dwight — Mon, 24 Sep 2007 09:49:58 GMT

Anything but JPEG.
PNG is still compressed but better.
TIFF is a professional pre-press format that holds more information than Archicad can use. It can also support an alpha channel if you like to use them.

Thanks Dwight.
@Scrat.

First make gradient fill in elevation, and copy it and save as TIFF.
You can use this for your material in rendering, also for Open GL.

I needed to set Internal Rendering Engine but I made it Thank you a lot guys

Now, another problem. I created fill in Adobe Photoshop and made a material. Now, when I apply it to the wall it's not stretch but tile... How do I make it stretch?

Re: Wall painting - fill effects??

You don't - you need to make the original the correct size, then that should be reflected when it is imported in the Material dialog. Otherwise you can override the size there (not that I'd recommend it). Either way, be sure to check the Keep Original Proportions.

Cheers,

The easiest way to stretch any image to a full wall is to use Archicad's Material Dialog for the Internal Engine where the exact dimensions can be entered for any image regardless of proportion.

Measure the wall, change the material tile size to match.

Disproportionate stretching CAN lead to chromatic pixelation, however.

So, if I have 3 walls with different dimensions, I should create 3 different materials...
