Tobak left me a site mail, but I can't reply from work so I'm starting a thread.

I mentioned on Tobak30's latest image that I have had difficulties with Indigo and non-uniform normals, so what do I mean by that?

Take a mesh select some polys and then hit the flip normals for those polys, for me this is making indigo barf about 1 in 5 times. Ok so how did I reach this pearl of wisdom? well it came from experimentation which all started with the thread here on using subsurf divisions and scale along normals multiple times to create an abstract? If you remember this quick technique can produce some pretty weird complex meshes and for me they fail every time in indigo renderer. So I started playing and figured it was because the normals were getting messy.....

anyone else found this problem, I've done some fairly large scenes in indigo when it comes to number of objects or poly count so I think I've hit the problem?????

Can't say I have flipped any normals at all. (Don't know how to do it) But could indigo exporter stall cause of to much use of subsurf? Or is it my computer it is wrong with? My computer is pretty old (4 year old amd 2200+ with 1 gig of ram) Could be that... Not shure. It converts the object fine for a moment and then stalls at a ceratin point. Demanding lots of memory and using my cpu to the max but not going anywhere. If it does it is to slow for me to notice.

Or is it something about the script that is funky. It seems like it at least one over at the indigo forum that has the same problem.

By the way I am looking forward to the next instalment off Indigo. Stable version that is. As every test version has big improvments that could be defended as versions. Any real version is taking grand leaps.

Not sure about the subsurf - are you aplying the modifier or leaving it in t he stack?

remember about keeping your subsurf down, never go above level 3, and level 2 is usualy good enough.  i remember from your files that you had all your subsurf levels at 6, dont do that, as indigo has a normal smoothing feature that makes it like it has a level of 6 while only having a level of 2
