View Full Version : Split Poly / Inverted Normal Problem

Hiya,

I'm using the ConnectPolyShape (CPS) Script to model a head.
(not sure if the CPS script is at fault of the following problem, but i thought I'd throw it in just in case)

My problem is after hours of modeling without any problems I am now at a point where if I use the split poly tool on any face of the control lattice (cpsBase), some of the resulting faces of the smoothed version (cpsProxy) look "off". When i look at the smoothed version's normals, the "off" faces have reversed normals. I tried tried re-reversing them, put it didn't solve things. I can't figure out why this started happening all of a sudden or how I fix it to "split in the right direction" again.

Here's a printscreen of the problem:

The blue airbrush are the splits I added, with the problem areas being circled it red.

If anyone has a solution or an idea to try, it would be greatly appreciated.

Ok folks,

After tooling around for awhile longer I found a way to fix this. Thought I'd post it to save ya'll some time if ever needed.

All I did to fix it was delete my cpsProxy mesh (smoothed mesh) and then selected my cpsBase (control latice mesh) and and then went into teh Connect Poly Shape script window & pushed "Connect Poly Shape" to have it regenerate a new cpsProxy mesh.

If anyone else has any info on what may have caused this, I'll all ears though

Thanks

Its probably just a result of your messy mesh. With 8 sided poly's which are non-planar.

Yes, definitely something I need to work on (this is my 2nd try at head modeling...) I hadn't gotton to the back of the head at that point for work. I should start keeping everything 4 sided all the time before it becomes habit.

Though, that doesn't explain why it started all of a sudden (it was that messy for hours) & went away as soon as i generated a new one from the proxy. The mess is still there (until i go clean it up! :)) ... or maybe it does...what do I know...

Thanks for the input. . .
