You've got a hierarchical node above the object which has an awkward scale? For instance a group? It's very easy to recreate this dilemma. Make any new object in Maya, group it, scale the group along one axis. Now select the object and rotate it. Skeeeeeweeeeed.
sounds like double transformation! curve controls surface and parenting both to a controller results in: parent scales curve which scales object (as long as it has history) AND parent scales object created by the curve again. solution: parent only the curve to the control but not the object.
Ok, here are the screenshots of a very simple sample object. The engine i used for testing in the cryengine. On the HP Object is a turbosmooth modifier applied. As i wrote if there are not stitched together, it works fine. @earthQuake i tried both ways, before and after triangulating the objects.
Your low poly objects are not capturing the high poly object. That simple. You stated it yourself. Add more geo to match the low closer to the high and you will see your blackness go away. Otherwise, deal with it! Will the camera view ever be that close to the object?
When you say that your textures are changed, do you mean uv's? Replaced/exchanged filenames ? Does it happen with collapsed objects? Very big objects? Objects that have a topology-changing modifier in the stack? Also, what version of Max are you using?
Check the Hypergraph or Outliner to see if your objects are still there. Sometimes re-assigning a shader to an object that appears to have gone fixes the problem. Also try a quick planar projection to make sure the objects have UVs. Weird, I know, but it sometimes works.
If you need particles to take the shape of an object, you can use the Position By Object operator. Make a box, assign that box as the position object, and then change it from surface to volume. I think that might get you closer to what you want, maybe.
Also consider object scale. You could have very large objects (like vehicles) which use tiling textures (and fwvn where it makes sense to do so) broken up with decals. So you get the benefit of super-efficient texture use while not being limited when it comes to adding unique details wherever you like. However — I've just…
I'm getting the same error. The listener doesn't look helpful, it's just " >> MAXScript Rollout Handler Exception: -- Unable to convert: undefined to type: Integer << " Max 2012 64bit, Windows 7. What's odd is that only some objects trigger the error. I haven't been able to get a teapot to error out, and it only happens…
Off the top of my head, there's Lattice and Wrap deformers, With lattices, you can use the Deformer set editor to add/remove additional objects as you go. Wrap deformers can be a bit messy in general, but you can use them like a custom shaped lattice and can give great results depending on the scenario. I don't think you…
