Been attempting to complete some work in Carrara 5, with my just-installed 5.0.5 upgrade. Before I post a long bug list to Eovia I want to make sure these aren't just me being stupid (and not really flaws in the program at all). Vertex Modeler: Marquee and Lasso selection tools not selectable at all. Deleting an unrelated polymesh can erase group information (i.e. named polygons) from another polymesh. Keyboard delete key works inconsistently; sometimes deleting, sometimes cutting, sometimes doing nothing at all. Even using nothing but camera controls (option, control-option, command-option), the camera goes into that non-euclidean space thing and has to be restored to default. The vertex modeler is incredibly slow...slower than it has been for several whole-number program versions. Turning just an imported Poser head (Aiko3's head, in fact) would cause the screen to freeze for up to twenty seconds. Lathing a simple polyline made a mesh with overlapping and unwelded edges in the middle of the mesh (not just the original polyline -- I'm used to that). Display inconsistency when switching SubD smoothing on and off -- sometimes it would stay in smoothed mode, sometimes not. Obtrusive (and incorrect) error messages while editing a polymesh -- whereas in version 3 or 4 I could duplicate an edge, connect it in then fill the new polygons, in 5 I could only use tool or key command (depending on the operation), and was constantly having to click through error messages. This went on even after I emptied the original polymesh so I was working only with verts and lines. Tools often took more than one click to select. Particles: First, kudos for making particles that have collision, respond to scene forces, and have a metaball mode. Particles "leak." As an experiment made several vertex-modeled bowls. In every test a significant number of particles would fall through the sides and bottom. Setting surface accuracy to "high" did not help, nor did increasing the particle size or the tightness of the mesh. There doesn't seem to be a way to save a particle run. Even rendering a scene that has already had particles generated, generates particles from scratch. Saving the entire particle animation (as physics are saved) would be a wonderful thing. Texturing: When setting index of refraction from pop-up list, the box value doesn't change. As soon as fresnel term has been invoked for transparency it becomes impossible to make either preview or a rendered object transparent -- no matter what settings are used. Indeed, adjusting the settings seems to create bright lights on the surface, not transparency at all. It doesn't help that the meaning of the numbers is inadequately documented. UVmapper: Window does not remember previous size or settings. All in all, I found 5.0.5, as compared with 4, incredibly slow, frequently stalling completely, many of the functions that had worked before now working inconsistently, and several things didn't work at all. I am strongly considering deleting it and re-installing version 4.
