New Parts for LGEO Library

[Sven v. Beuningen]

Hallo together,

I read the hole post and are quite interessted in Lego brick rendering. First of all I'd like to thank you for the work to provide the high quality parts for rendering.
I tried to do the setup like described in the first post, but I'm not quite sure if I did it right. Since I'm not very familiar with PovRay I have the question about the following step in the introduction:

You may want to put the lg_xxxx.inc files in your usual LGEO directory and the xxxx.inc files in another folder (don't forget to declare it in PovRay or it will not find the requested files)

I did the first step and created a directory called "parts" in my LGEO directory and copied all xxxx.inc files there. What I'm missing is the last part. How to I tell PovRay to look for the files in that location?

I tried to render a part without adding the directory somewhere and I got a rendered brick, but where is the difference if I add the directory? Do the bricks look different?

Best Regards

Sven
