The question asked in the poll suggests that it could be acceptable to answer yes. This is not good as it is a starting point to spread ignorance.
Copyrights laws are clear on the matter, maybe u could read some

Another point is that using textures or parts from another mod doesnt constitute a derivative work by itself, but rather theft, unless author of texture or part explicitely allows copy.
And if you want to be totally clean legit, you must include all the licenses of all the parts and textures that u have used in a text file that must be distributed with your work.
From my experience however, textures copyright is unmanageable, everyone builds on other people work, sooner or later. Who takes care of license for a texture ?
So while the law is clear, it is not enforced on some specific things wich have been integrated in work/business culture.
In fact using textures/part from another work could also be interpreted as sampling, like in music, but am not sure, it would need some research.
Better stick to the law, and most of all, respect of other people work, specially in a small community.
