Lines in Walls

[Karl Ottenstein]

Sure glad you posted the image so we can see what's up. 😉

When you say 'get the lines out of the siding' - do you mean that you want the walls to be green but without the horizontal lines? If you've been changing the texture size without seeing a result, then it seems that you have log walls turned on for your exterior walls ... with square faces.

If you don't have log walls, then perhaps you've been changing the fill size but not the texture size. The fill doesn't show up in the rendering window... check the texture.

HTH,

PS BTW, you want to put an empty opening in the chimney (wall) inside the house so that the firebox of the fireplace shows up, and also want to use the options in the photorender window to stretch the background image for the sky.

I'm confused by your first question, then, where you wanted to get RID of the lines. So, the question is really how to get a realistic siding material?

Too many possibilities to answer. An easy answer, without alpha bumps, is to paint a more realistic shadow line (soft shadow) in the texture image... it'll still look fake because it won't interact with the light properly.

I can't see the jaggies that your'e talking about, but if they are present, set method to best, antialiasing to best, click the Options button (still on the Effects tab), and check 'texture antialiasing' and slide the slider all the way to the right. If that looks OK, then try the slider at different positions to the left to speed things up.

Assuming that you have your 'resulting image' pixel dimensions set as you wish, change the picture magnification % until the picture is at least as big in width and height as the target. (This is just an easy rule of thumb ... if you know that part of your model will be covering up the background, then there's no need (other than aesthetics) to scale the background to be under the model.)

When the background image is larger than the rendering image, you'll see a rectangle in the background picture preview. Depress your mouse inside the rectangle - you get a hand cursor. You can move this around to choose which part of the background image to use.

Note, that stretching bg images like this can give poor results and that for quality renderings, you're better off resizing the background precisely in Photoshop - or even applying it there (or in Piranesi, etc.) during post-production. Some programs, such as C4D can take the background image into account when doing global illumination. AC does not.
