i tried realizing it with many small brushmodels moving one after another so that they together might seem like an escalator handrail, but it looked ugly, because the brushmodels, when moving in an arch, werent making up a smooth circular surface - there were visible corners. to make it look more realistic, its necessary to decrease the size of the models and, obvious increase their amount. and, in addition to it, write a bigger script.
failed in making it with brushmodels, i decided to use a moving texture. i made one for straight parts of my handrail, but, regarding circular parts, i dont know how to make a texture rotate so that there are no seams between straight parts and rotating ones.
