Good to hear it worked! The texture count is how many times RC has to generate an image texture file of your chosen resolution (4096x4096) in order to generate all the necessary textures.
If you have a large or very detailed project you will need either a large texture resolution (8k or 16k) or multiple texture counts (usually either on 4k or 8k).
In the image above RC had to generate 9 textures of 8k each in order to get a texture quality of 93%. The texture quality is calculated by determining the optimal pixel size (basically the average pixel size in physical dimensions).
If the texture quality is at 100% then this means that each pixel in the texture image files is as large as the average pixel size of the project.
