SketchUp Texture - upper left - Rendered Texture - lower right

There are a couple of things you can do:

1. There is a setting in IRender nXt to lower the quality of the textures when rendering. The default is to downsample them because SketchUp users often import textures at a very high resolution which made the files too large to render.

This is on the Special Setup Tab. You can set it to 0 to turn off this effect.

(In the middle right of this dialog).  See: Texture Resolution.

2. Also, we have a feature to import the full complement of Arroway texture images to apply  the specular reflection map, the bump map, etc. to make very good renderings from Arroway textures. See: Texture Set

Thanks, no the result is much better.

Sorry to reply to an old topic, but I recently bought all the Arroway materials.  Some of the materials look good, and others look just OK.  The interesting thing I noticed is that none of the renderings look anything like their demo scenes.  I'm not sure if it's something in the settings or something they are doing in another program.  But thought i would pose the question to you all at Irender.  Is it possible to get a tutorial or youtube video?  I go through the create texture setup no prob and it assign settings...the finished rendered product just doesn's come out as photorealistic as advertised on their site.

Since you did not include any images, it is hard to know whether you are having a problem with resolution, or other aspects of the rendering such as reflections. Here are some guidelines.

Here is a rendering using a sample, low-res Arroway Wood texture, (Boards 002), from our library:

This image is fairly flat. So we will show some ways to improve it by adding lights and objects to the model to reflect.

Here is the Arroway sample image for this texture:

Here I zoomed in to get a view angle more like the Arroway sample. I also lowered the intensity of the sun, so that I would get more reflection from the sky.

We do not have the same high-resolution as in the Arroway sample image. But this is because I am using a low-resolution sample of the original Arroway texture.

If you are using the hi-res Arroway textures and not getting full resolution, make sure you have turned off the texture resolution on the Setup Wizard:

For this next image I used an HDRi sky, rather than just the sun and standard sky. This provides better reflections from the sky itself.

In this next scene, I kept the sun and sky, but rotated the entire scene so that there was more direct reflection from the sun.
