Normal projection issue!

Toku

Hey guys, I have been using TB3 to bake my normals for a prop I am currently working on. I've hit a roadblock though and as far as I am aware I didn't do much wrong, The baker is giving artefacts on a face (not along the edges)  which has good high/low overlap and the cage is offset enough to cover the high. Also checked the unwrap incase there were any overlapping/flipped faces but there are not, The ring of polygons have been unwrapped straight but I have done that on other areas of the mesh with no issues.

Have the same problem on my Marmoset 3 test mesh. No overlaping uv's or so.

In Substance Painter (with no cage), I haven't got any artifact:

Can you send me your scene so we can debug this? Easiest way is to go to File -> Export -> Scene Bundle and then zip up the .tbscene and /assets/ folder.

I'm having this problem too

Toku

PM'd you the files for debugging

Has anyone any update about the issue or its solution yet?
Thanks !

EarthQuake

Sorry, but we do not have any updates or solution for this one yet. It is in our bug system and we plan on investigating it and will try it find a solution for a future update, but I can't give a time frame for when that will be at this time.

I'm having  similar issues with one of my bakes, with strange projection issues in some flat surfaces of my model. I can PM you the scene if you want.

EarthQuake

@Yogensya if you can send me your scene that would be great. It looks like the same issue but it will be good to double check just to make sure. You can package your scene up by going to File -> Export -> Scene bundle, and zipping up the .tbscene file and the /assets/ folder. PM or email me a google drive/dropbox link, joe@marmoset.co

Thanks!

We've looked into this more and have been unable to reproduce the problem on our end. I had initially thought I was seeing the same thing with one of the example files, however, it turned out I wasn't updating the preview material, so it didn't show me the updated result (which was working as expected).

We think this problem may be some sort of hardware or driver specific issue. Please post the following information if you're having this problem:

1. Operating system and version
2. Graphics card make and model
3. Graphics card driver version

Also, try updating to the latest graphics card drivers, and if that fixed the problem, please let me know.

Thanks!

I've had artifacts and sometimes even Toolbag crashes with the baker with 2 different drivers. The arctifacts don't appear to be completely random, they are consistent for each mesh but I don't know what causes them to appear in the middle of flat surfaces.

For me, the preview as you mention doesn't update either, I tend to poke the offset slider and that forces it to rebake for me For this reason I usually switch Autobake to Full.

Just in case it is of any help I've recorded a video loading 2 meshes in a completely new scene and toggling options on and off to show how it affects the errors in case that helps (you'll see me go back to the offset slider after each edit because of what I've mentioned above :P

I can confirm having the same problems like what Yogensia is showing with his testing files. Tried multiple settings, but the artifacts keep being rendered on those flat surfaces for some reason.

@RafaelDeJongh

Can you post your OS/GPU/GPU driver information?

Thanks

@Yogensya

Thanks for the information. Can you (and anyone else who is having the problem), try installing Toolbag 3.00 and seeing if that fixes the problem?

@EarthQuake Tbag 3.0 does work fine for me on this scene. The broken normal texture loads from disk but when I hit the preview button and it updates, the errors go away:

Hi everyone,

We're looking into this problem on our end. It's interesting to see that 3.00 works, while 3.01 doesn't. There were actually several revisions of the 3.01 build that ended up being released, one of which had a baker flaw almost exactly like the one we're seeing here. I'm wondering if perhaps this problem is a result of being slightly out of date.

This will be easy to check. Simply do a full uninstall, and then reinstall with the latest 3.01 installer here: https://s3.amazonaws.com/mset/download/release/toolbag_install_301.exe

Let us know if this fixes it. If not, we'll keep tinkering. Thanks for your help!

Same for me,3.0 works fine.
I tried installing the latest version(from your website) and still having the same problem.

Vincent - can I ask you to double check that please (using the link I posted)? The reason I ask is that I'm only able to reproduce these artifacts with the "old broken" 3.01 build, but the 3.01 build on our site doesn't seem to have this issue (and neither does the upcoming 3.02 release). @Yogensya & @RafaelDeJongh & others - curious to get your thoughts too. This seems to be the solution, but I need to be sure.

Thanks

Yogensya

@jeffdr For me, all problems seem to be gone even after reinstalling 3.01 with that link, tested my scene a couple of times, worked perfectly. Not sure if it fixed because I had a bad revision like you said of because of the mere fact of reinstalling.

In he past I've always installed new versions on top of each other (and still had Tb2 installed). Not sure if any of that could be related but I think I'll uninstall properly from now on just in case.

I guess it's time to introduce more granularity to the product version
