[chimerax-users] Surphace representation of multi-model pdb and moovie recording

Dear Chimera-X users ! I am working on molecular visualization of membrane system from the md trajectory loaded in the Chimera-x using the open coordset true command. The issue is with the surface representation of the membrane: transparency :OL,PA,PE,PC 80 target s which are applied only on the current frame (not on the whole trajectory). Also when I try to make a movie of the system the presence of the surface does slow down everything. Which options could be useful e.g. to decrease the quality of the surface representation ? Many thanks in advance Enrico
