Hi Krishnan, The probable reason for it being slow to play through a morph with a surface is because ChimeraX will recompute the surface at each time step and that can take seconds. The way to avoid that is to have the morph as say 50 separate models that you play through with the mseries command where the surfaces have all been computed in advance. The mseries command will just hide and show models which is fast. If instead you have one morph model with 50 coordinate sets then the surface cannot be precomputed. To turn your morph into separate models save it to PDB or mmcif file ("save morph.pdb model #3 allCoords true"), then open that file as multiple models ("open morph.pdb coordsets false"). Tom

I morphed a 180kda protein. Trying to view it in stereo with surface. Works good but slow. Any tips/ideas to make the morph faster?
