The rendering bug cured that pulls the model into streaks into the top left corner of the screen when the user has text-edited extra Weld commands into the CR2 file like Bloodsong recommended. Re IK chains: Bugs to be cured in converting coordinates between IK-on and IK-off modes. In CR2 flles preferably a seperate inkyActor `chapter' to handle properly the extra articulation created by IK-parenting an IK-goal to something. Ability to weed out unused materials. Some Poser models' CR2 files contain a confusing archaeology of disused materials, so the user finds pairs like "nipple" and "nipples" in the same model. My utility GETCOLTX, among other things, lists (but does not delete) unused materials in a CR2 file by comparing with the .OBJ file. Ability to tell Poser's renderer to make the texture map color overrule the material color instead of combining with it. Ability to install (and delete) an alternateGeom without a lot of fiddly text editing. Clicking an alternateGeom's parameter dial to show a dropdown menu of the names of the alternative geometries. (My two frogman's rebreather model's breathing masks both have alternateGeom's.) Cure various faults in handling of curve chains: necking-off; funnies when an offset or rigid part of child of a curved part; funnies wheh a curve chain is an IK chain involved in an IK-circle, including (a) sudden jumps between frames when the chain is animated and (b) the chain zigzagging due to some misbehavior of whatever spline-fitter is used to work out the path of the curve chain. When welding the join where a rigid part joins a non-rigid part, move the edge vertexes on the non-rigid part right up to the corresponding edge vertexes on the rigid part.
