Im trying to extrude a 4 million polygon model for 3dprinting but in zmodeler qmesh or extrude are frying my pc. Same result with decimated 1m poly model. Any other solution for extude high-poly models?
Try Dynamic Subdivision. Disable smoothing (SMT) and set number of subdivisions to 0. Adjust the thickness and offset (inside/outside/mixed) sliders as required. When done hit Apply to turn into real geometry. Reduce the polycount with Decimation (Zplugin).
