face colors
« on: February 17, 2010, 02:39:51 pm »

I know if I selected a face from the front it is yellow and back blue.  But I have faces that are different shades of yellow.  Almost a green color.  I would think it would be a mixture of yellow and blue. 


On this I had to selected front and back to get some of the faces to show up.
Not sure how to fix it.

Hm I kindof remember a bug of this sort in an older version of anim8or. What version of the program are you using?

It might be a mesh error as well, a fix would be to delete the points and model the area again.

(btw, at the top corner of the darkyellow face, i see a small mesh error, with a line going through the corner, you might want to fix that)

Honestly I'm pretty sure it's just the shading in Anim8or.  I don't think there's any issue or glitch.

.95 dec 2006 is the version.  I have found if I cut the shade changes  I think that is what's up with the corner piece.  I have tried to delete the faces and lines and redraw the line but I get the same result

Hiho: I think it is a glitch, i f you see other selected faces facing the same way, they still have a lighter color.

I am pretty sure it is because of the version you're using gattispilot, try downloading the latest beta version and open it in that.

Actually, I am quite sure it's a shading matter ;) It doesn't look greenish to me, just dark yellow.

Looks like you imported a 3ds file. Make sure the mesh is completely ungrouped (ungroup it a few times), then select all the points and go to edit->merge points. Set the merge distance to .005, and hit OK. See if that fixes it. If it's still off-color, delete the face, you may have two stacked on each other.

No! I am SURE it is just because youre running pacman while working with anim8or, thats of course asking for trouble!!

</sarcasm>

Jokes aside, it could be a double or seperate face indeed. Maybe if you post the file we can see.

Change the view to fully shaded, or do a quick render, and check the result.  If it's related to a double face the error should still be visible, if it's just the way Anim8or shades its faces in Object view then no issue will be visible.  I'm with Raxx and Hiho on this one, I can see nothing in the supplied image that shouts "problem" to me, other than the aforementioned corner cuts performed in an attempt to fix the issue.

Here are a couple of images wireframe  smooth render images.  As you can see some of the orange color is faded to almost white.  In the render you can see a dark area under the left arm.

the material setting on the orange are A.300 Di .700Sp1 Emis.1 rough 200 bril 1.  I am using a bitmap image for the orange color

This looks like you've just got some creases that can be fixed by double clicking the mesh and setting the smooth angle to around 60-80 degrees or more, based on what you desire it to look like. Of course this is based on the assumption that you attempted to merge the points first.

As for the orange color faded to white...are you talking about the materials? Give it 0 for spec if you don't want the white specularity effect. Also, an emission of 1 can affect your results, based on what color emission it is (white?) and the strength, along with the ambient color/strength you give it...and basically all other aspects of the materials :P Not to mention you should take into consideration that by default the workspace has a front and back light.

If messing around with the smooth angle, merging points, or changing your materials doesn't fix it, you might want to consider sharing your mesh with us so that we can take a direct look at it. Of course, it doesn't help that your mesh is horribly triangulated as well...

Ok  How do I fix the "mesh being horribly triangulated ".  I am using this for Orbiter.  So I need to cut the mesh to add a textures of those badges on the sleeves. 

Maybe remove the lines from the shoulder to the elbow and redraw?

I guess I was wrong, it was just a shading issue. There actually was a bug like that though some time ago!

I'm glad you got the mesh fixed.

To get rid of triangles you can select two triangles and merge the faces (shift-m) so youre left with one square.

There's also the untriangulate script located in the ASL scripts database: http://www.anim8or.com/smf/index.php?topic=1705.0

For use in-game it doesn't matter really if it's already triangulated, since when it's put in the game it gets triangulated anyway. However for in the workspace (anim8or), it makes it easier to work with the mesh and easier for us to look at and not assume it's some weird conversion problem. Also, some areas of your model seem like it could use a bit of optimization, but that shouldn't prevent you from getting it into the game.
