Texturing Issue - Black Sections

Anonymous — Fri, 03 Feb 2017 18:10:34 GMT

Hi there,

I'm currently developing a basic game for a project I've got at college on which we will be using Stingray to build the game in.

I've created around 7 assets for one room, but I'm having issues with texturing with 2 objects. I unwrapped all of the UVs and sent the object into MudBox to texture. When I assigned the texture to the object in Maya I'm getting random black patches on certain parts of the object. I've checked the UVs and also even re-checked the texture in MudBox but everything seems to be fine. I have attached an image with what I mean.

Cheers'

George

Do the black areas show in actual renders or just in the viewport?

Hi there,

The black areas show in renders and view port.

Hmmm, possibly some bad geometry in there?

How many vertices are those pieces showing they have?

Are you able to post the scene file?

When I imported the mesh into MudBox, there was no errors displaying. I've checked the UV's just in case anything was overlapping but couldn't find anything at all.

Not able to attach .ma files, forums won't let me. 😞

You'll have to zip the .ma file first.

The uploaded scene file seems to be a bit different, but I was not able to see the issues you having in the viewport.

Are you getting any error messages in the script editor?

This is what is displayed in the script editor.

I'm not seeing any issues there...

Hmmm, what render engine does the issue appear in?

Also - what video card are you using?

I'm using Stingray PBS, it only shows when I use Maya Hardware 2.0

My graphics card is Nvidia GeForce 950.

Strange thing is, it's only 2 models I'm having this issue with, all of the others have been completely fine.

Sorry I'm no help on this one...

Kind of looks like a z-sorting issue, does it show up once inside of your game environment or only in Maya?

Just in Maya at the moment, haven't tried it in Stingray yet.

Hey were you able to solve this issue at all?

I'm having the same problem

Hello,

You probably already tried reversing the normal but if not: Select one of the black faces and try

MESH DISPLAY>REVERSE ( screencap included where to find).

What happens when you switch to flat shading or flat lighting, does the problem go away?

If it does fix the display issue, then I think it is just a display issue like an artifact. If it shows up correctly in game engine and in render, then again I think it is just a preview display artifact. The flat lighting and flat shading can be helpful, especially once you have advanced materials/lighting applied.

Good Luck!
