This is a amazing pack of great textures. Your work is the best thing Ive seen in my time with architectural visualizations!

I am new to this art and have used the Arroway firstname.lastname@example.org in the attached image rendered through Sketchup, can you tell me why it appears so grainy?
The image seems to be missing.
Sorry, I have attached the image. Also, I have tried importing the Arroway wood-077_wenge-3_d texture through the Texture Set dialogue, however, when I painted the texture on to the furniture it was all grey instead of the dark timber colour
Judging by the image, the textures seems to have been resized without filtering. This would naturally result in visible aliasing for most wood textures. If you 3d application does this automatically, you could try to resize the textures yourself properly (e.g. with Photoshop) before importing them.
Specific questions regarding the material creation workflow for your 3d application are best asked in a user forum dedicated to this application.
