Getting BLACK geometry - HELP!

SwampCat84 · Oct 2011

I dont know what Im doing wrong here... When I put a texture on the geometry and then scale it in the -x my geo turns black?!?!?:poly118: I can see the texture on it at an extreme angle but not from the front. This is only in Viewport 2.0... It seems as if the light just isn't reacting as it should on the object. Ive checked my normals and they are all facing the correct direction.:poly141: ANY help would be MUCH appreciated! Thanks!

would love some screens or info on the material or anything?

Take a screenshot of the issue so we can help you.

We don't even know what app you are talking about dude. Be more clear if you want help.

Just checking but do you have the Model mapped properly?!?

(Viewport 2.0 is a Maya feature)

Yea, its Maya, sorry.. I have everything mapped out right.. Someone said to freeze transformations and then flip my normals so gonna try that... Ill try and get some screen shots up here soon...

Here ya go.. Some objects it doesnt have an issue with, some it does... When I check the normals direction it shows them going the correct way... I dont get it...

I've had this happen recently and unlocking the normals usually fixes it. Mainly happens when you duplicate and scale -1.

Mark Dygert · Oct 2011

In max that normally means you are looking at the back side of the poly and it needs to be flipped. Typically that happens when something is inversely scaled like using the mirror tool.

I'm not sure if Maya suffer from the same backwater functionality...

Hmmm, just Freezing Transformations seems to have fixed it... Thanks everyone!

That hasn't actually fixed it. Its normals are still reversed, but Maya uses an attribute called "opposite" to make it appear correct. After making mirrored geometry like this, you need to mesh>combine it with the original, at which point it inherits the original's normal direction.

If you need it to remain a separate object, do the following :

Freeze transforms
Hit Ctrl+A to bring up the attributes box
Under the shape tab, find "render stats/attributes" (can't remember exactly what its called it's called just now, don't have Maya here)
Untick "opposite"
Then finally do normals>reverse

All of that insures that you'll have a clean piece of geometry that won't cause you problems later, particularly if you export to other apps.

Cool, Thanks!
