hatched faces after beveling

good evening!


I have a problem with hatched faces after I beveled some edges. I used targa/jpeg files which I applied to the object and everything is fine exept those little faces created from beveling. they just don´t want to be textured - only show up those white stripes. maybe someone can give me a hint what to do. Is there a limit to the size of a face (very small faces) which can be applied with texture?

I would be happy if someone can help me, cause I really don´t get it - thanx in advance!

Sometimes after you create new faces they have no UVs. I would re-apply your mapping style (spherical, cylindrical, whatever) and all should be well again.

ty for the advice!
I´ll keep it in mind for the future.
in this case it was a matter of the render-software
at least I think it was user added image

-> with maya software i got stripes,
-> with mental ray they vanished..


have nice time!

did you have dmap shadows on? It sounds like a problem I had with the shadown map not being high enough res. And that would explain why it went away with Mental Ray aswell.

Post a pic of it.

hello pure

in fact I don´t even know what dmap is...
tried to find that (-> kick me in the nuts <- ) item somewhere in the menus, but - I can´t say if I have it on.

I post U some 3 pics.
but my next problem coming up is -
the bumpmap i created in photoshop for the pumpkinhead is divided equatorialy aroud the head. in PS I just layed the texture_pic over the exported UV_snapshot like with the other I created before - don´t cared about cropping around the UVcoords. thing is - the UV_coordinates have been setup in a strange way - not from top to bottom but from eyelines to the back of the head. I wonder if I can manipulate this UV_setup.

until now I didn´t find a solution - means I have to take a closer look on the settings from the other PS_bumpmap i put on before - oddly enough it was the same UV_snapshot with a similar bumpmap like the actual one and -> it worked fine. (arghh)

here are the pictures

and tell me if it bores U by getting from one noob thing into the next.

thx for your help!

Ah, that means those faces don't have UVs. You'll want to UV map the model.

yep, it was automatically mapped by default I guess.
with spherical mapping it workes out well.

thx!

good news that you fixed it. Just FYI dmap shadows are emitted by lights. if you look at the properties of a spotlight you will see it as an option. My suggestion was that if you were getting weird hatching it can sometimes come from the fact that a dmap shadow doesnt have enough resolution to shade the objects properly.

sounds logic to me,
but out of my rudimentary understanding for maya -
I try to work with it since two weeks now -
I´d say it was only a matter of incorrect UVmapping.
otherwise I probably couldn´t fix it..
next thing is creating the smoke, I have no idea what to begin with.
didn´t find any good beginners tutorial anywhere in the net.
so I guess I´ll start with the maya helpfiles.

i post U a pic what I´ve done so far.
