SOLVED: Texture/Smart Material not appearing on a section of my mesh

stumpinater

Has anyone had this problem?
I am trying to apply a smart material to a certain section of my mesh, defined through the colour ID map, but for some unknown reason, the material will not appear at all.

If I apply a smart material which is not allocated by the colour ID it will appear on that section of the mesh though.

I have attached the images that show what I mean.

Hi Stumpinator!

What happens if you click the black mask and click "ok" right away, does it "Jump back to life" ?
If so, this is a bug that has been fixed with the latest stability patch, available here:

Hey Eric,

I wish it was as simple as installing the patch I had already installed the stability patch a few weeks ago. I have done it again just to make sure nothing was missed, but still nothing has changed. for some odd reason, I have a few white dots which appear just on the outside of the colour ID.

stumpinater

any other ideas on what could be causing this?

Eric Ramberg

Im not entirely sure, would you mind posting the project files so that I can take a look?

stumpinater

Yeah sure, what will be the best way of uploading the project, do you just want the maps?

Eric Ramberg

You can zip the project-folder and upload it to dropbox or something similar!

I am unsure if this is any use to you, but in the project folder the "BaseMaterial_ID" does not mask off the area with the colour defined in the ID map.

I have made a change to the original ID Map adding a logo, but its done exactly the same thing, so now I have two areas which will not receive any material. This is the only thing preventing me from signing the project off. I hope there is a something that can be done.

I'm just scratching my head now at this point...

Sorry it took some time, I downloaded the project and looked it over, it seems to be some sort of issue in the OBJ-file itself. But I just saw that you posted this in the PImps & Preview section, does that mean you figured it out already?

stumpinater

Hey Eric, I never really managed to fix it, I instead exported all the maps and clone stamped in the area that area on the maps that needed it. Bit of a cheap fix, but hey, its a walk around I guess.

Thanks for letting me know about the OBJ, at least if it happens again I know that this may be the issue. The export settings from Maya I only had ‘Groups’ and ‘Smoothing’ selected.

It looked like there was some sort of overlapping issue over the tank filler cap, so maybe that is why it didn´t work!

stumpinater

how do you mean overlapping?

Eric Ramberg

When holding "C" in 3DO I could see a weak outline of the "filler cap plate." It looked like there was overlapping of some sort in the mesh itself.

Hmm, odd, I will take a look into this when I get a chance. though everything has rendered out well in Marmoset Toolbag 2 but I did use an FBX instead. Definitely worth checking out the OBJ, and worth noting if I come across this in the future.
