I'm new to Blender and I'm following Blender Guru's tutorial on YouTube (https://www.youtube.com/watch?v=HlrgFS8AMMU at about 11:59).
So far everything has worked according to plan. First I added a cloth physics to the couch cushion with 5 pressure and 0 gravity. Then I tried out the cloth sculpting brush on a flat plane to make sure it works, which it did. I selected my object (couch cushion) and moved to sculpt mode. The object turns dark grey, and sometimes I get a warning that says "object has non-uniform scale, sculpting may be unpredictable." When I use the brush and try the space stroke method or line as the tutorial suggests, nothing happens. I checked my settings to make sure they look the same as they do in the tutorial, and they are.I have no idea why it is acting up.Any help would be great, thanks.
