Object black after boolean

[Cyresto]

Hi everyone,

Really need some help here. I'm working on an animation for uni, and it involves aliens. I'm trying to boolean some bulletholes into an alien mesh to create a corpse, but after the boolean is done subtracting, the mesh is black.

Things I've tried;

• Re-assigning the texture- object remains fully black. Taking off its texture with $.material=undefined doesn't result in it having its default object colour either, it remains black no matter what.
• Flipping normals. Object still black- turning backface cull on shows that the normals are correct.
• Using proboolean instead, but that just results in the boolean failing outright- for some reason, proboolean has never worked for me.

Any help is really appreciated. I've scoured the internet but found nothing helpful.

(Left is the mesh and the cylinders I want to boolean for the bulletholes to occur. Right is the result- the holes ARE there, the mesh is just eternally black).

I would have said check the normals but you say you already did that?

Can you post the black model here, I would like to have  a look at it

Yep, checked the normals lots, tried flipping them, etc.

Here's a link to the file on Onedrive, feel free to take a poke;

Hi Mate,

did you applied poly id on your model? If so, please check the poly id of the model.

Hope this will help.

Thank you.

Just checked- poly ID is set to 1 on both the black and normal alien. They both have the same texture applied also.

I just managed to fix this issue- looks like his teeth were what was making the proboolean fail, so I detached those into a separate object and tried using  subtract on the cylinders again, and now it's working. Still no idea what made the original boolean-d alien all black, but this issue is resolved now.

Cheers to everyone who helped!
