I'm trying to poly model a helmet and I have some extruded spiked edges but when I try the Solidify modifier, my spikes get horribly messed up. Is there any way I can exclude them from being solidified? I've tried to hide them with H but since the modifier applies outside of edit it didnt do anything.
I tried checking only rim but that doesnt accomplish what I'm after, which is making the helmet somewhat solid to be printable. I'm not yet familiar with all the tools available so I dont know where to go from here. If I can have a solid interior without the spike distortion it would be perfect.
