Artlantis rookie

[Anonymous]

I'm reasonably new to ArchiCAD (using v8.1) and even newer to Artlantis.
When i export from the AC 3D window to a .atl file, and open it in Artlantis
the result is grainy and jagged. I've played about with the preferences and resolution etc, and also run through the rendering tutorial but i cannot seem to fix it. Any attempts at a final rendering are still ugly.

Anyone have any decent suggestions?

Thanks

I've attached an example.
Hopefully its big enough so that you can see what i'm talking about from it.

I'm also having the problem that some of my textures arent coming through with the model either. No matter how much i try reapplying them they just dont want to appear even though they appear elsewhere in the image, like in the windows and balconies you can see that some show a reflection whereas others, of the same texture, just show up as a plane of colour!

Any advice greatfully recieved,
Cheers.

grainie and jagged:
try to render image as TIF. Looks like you are jpg compressing it too much.

Planes of colour on the balconie:
There are several explanations for this. The most probable is that you have two objects in the same place (thus killing one of the laws of termodinamics...). Check in ArchiCAD if this is the case.

Textures coming tru:
I avoid using ArchiCad textures in artlantis. I ussualy export .atl without textures, and then attribute them in Artlantis. easier to manage the folders and lybraries.

A few more comments...

You said 'when you open in Artlantis' ... so if you are talking about the preview window, then yes, that will not look particularly good as it is not OpenGL nor is it rendered. If you are talking about a rendering output (your posted image is so small I cannot tell if it is a screenshot or a render), then what Krippahl says is likely: too low antialiasing setting and low quality jpeg.

Shader assignment. If you cannot drag/drop a shader onto a surface and see the result, then it means that a texture is assigned from ArchiCAD. Click the texture checkbox (it is really a button, even though it displays as a checkbox ... a stupid interface) and you'll get the texture dialog. Delete the texture image and close the dialog and then you can drag and drop from your shader library. (But, if you need to assign a texture image, you now see where to do that. 😉 )

Krippahl / Karl -

Thanks a lot, your advice was really helpful. I'll try and post a finished shot soon and you can see what you think.
