corrupted mesh

:D hy render dude :D
I will soon post my last works, sorry for my long absence, and not posting some news.
I'll spend some times learning a bit the program an remaking old shot (hope they look better this time).

I will quest you something: why some times the model made via SketchUp isn't right renderd via kerkythea :?:
...some strange artifacts appears: I'll searched in musch tpic, but didn't find such an example #-o
See image below: I'll tried different render preset, changing the camera, other material... ](*,)
(I'll ended the shot and corrected it in post production)

Thank's for helping me :mrgreen:

Re: corrupted mesh

:-k indeed seems some issue related to the mesh, perhaps faces not welded or duplicated, is the model made by you?

Re: corrupted mesh

could it be triangulation?
if you have a model in sketchup but you do not apply a material that contains an image texture, only a color, then you can get this triangulation artifact.
in KT, apply from Tools>Bitmap coordinates>rectangular.

Re: corrupted mesh

Thank's for answering me too Fletch!

I don't' know the option you explained me: can you just show what i have to do in refer to this print screen?
(I also attached a material in SK but the broken mesh still appears) ](*,)

Thank's again KT dude!

Re: corrupted mesh

In your attached image, there are plenty of narrow polygons in mesh. You should prepare model for rendering so that mesh has a even subdivision, like if you prepare model for displacement
example http://sketchupvrayresources.blogspot.f ... ision.html
Probably some manual work will be needed.

Re: corrupted mesh

...sorry dude, I'm a bit ignorant and don't understand what show in the tutorial you linked ](*,)

Like "nomeraodona" explain, I don't necessary must use the plugin subdivide & smooth (from smustard.com who isn't free): so what I have to do exactly?
:?: [... I've closed up the small chunks and increased the size of the right side of the "L" shape surface...] :?:

Any idea why with all the other model I renderized, i haven't got this kind of problem...? :-k

Thank's again.

Re: corrupted mesh

The best thing to do is posting the problematic part of the scene &/or model. So we can have a look at it.

Re: corrupted mesh

Your mesh probably have detailed holes (made of polygons)? These holes will force exporter to automatically made some "ill" formed topology. You really need to work out how a good topology is created.

Re: corrupted mesh

:mrgreen: !!! WoW !!! :mrgreen:
Thank's a lot. I was long time searching that kind of plug in: I'll follow the tutorial ad update my model.
Soon as possible I replay some news about it.
