CLO3D tutorial : how to create accessories part 2 - Glasses 

unfortunately, each avatar in clo3d is slightly different. So you might have the issue after you registered accessory on one avatar and the position is off when you add it to a different avatar. Normally I will save each accessory I create as a project file before I export. That way if I have the issue that the position is off, I can bring out project file to adjust the position and re-register to the new avatar. hope this answer your question.

I will do a video on that later. To quickly answer your question, when you select fabric and go to property editor-material- basic parameters...you will see texture map. CLo3d's preset fabric already have texture and normal map, however you would have to get displacement map and increase its amount to be able to see realistic texture. Displacement map will give you depth when you render. Here is a free website link you can just drag and drop your texture map picture to the site, and it will generate normal and displacement map for you automatically. hope this will help. cpetry.github.io/NormalMap-Online/
