Hi guys,
We’re sorry but today we have managed to release an Editor update that incorrectly modified Material assets during about 40 minutes today, before we reverted the change.
If you see unexpected black (or maybe white) materials starting today, please check the relevant materials to see if the Shading property has missing value. If it does, please set it back to Physical.
If your project contains many materials, you can find all and multi-select them like this:
If I roll back to the last change and set all materials to Physical, there won’t be any problems in the future, right?
Hi guys,
Yesterday, just when this situation occurred, our team was working on several things. Unfortunately, some strange things happened (all the objects got contaminated with reflections from the Skybox assigned in Settings/Rendering). This issue was resolved by switching all the materials to Physical as you suggested, but they no longer work as they used to.
Now the materials look flatter, have lost their reflections, and all the colors have slightly changed. Additionally, threads that used to appear gray now look white. It’s a bit frustrating.
This is a configurator for dozens of leather quiltings and colors. Manually correcting everything one by one would be costly and very time-consuming for our team.
Any idea what might have happened? We need them to look like they did before.
@Ariel_Cancio - Would you have another branch which you have not opened during that time, that you could look at to identify a problem?
If so, pick one material that looks different, and compare the tint colors / settings on both of these. Likely at least the diffuse, emissive and ambient tint. I believe those settings were unfortunately modified.
If we have another branch, the materials actually look the same in terms of their construction (diffuse, tints, etc.) but they are perceived slightly differently in the viewer, especially in terms of their reflection/specularity.
Have you compared all properties of a single material between those two branches?
Both branches use the same engine, so it’s not the engine difference. I really believe there should be a difference somewhere in the material. Please check all properties.
Ok, I will do it, thank you very much
Do we know if this will stay or be changed so it worked before the update? I personally haven’t been affected yet, but I am just wondering.
I’m not entirely sure I understand the question. But I just want to communicate that this was an accidental bug case that slipped our testing, we have no plans to affect peoples projects.
I get that. Sorry if my wording was off. Do you plan to change it back at some point?
We’re going to deploy the original changes, where the tint flags are removed, as the tint is always applied, soon with a fix to avoid this issue from last time.
Thanks!
Unfortunately, it happened again yesterday. Only a hard reset helped.
This has affected (at least) one of our projects as well. Shading type has been cleared, and ambient and emissive has been reset to default values. How would we go about restoring the original properties? This is a project with over 500 materials, doing it one by one would take too much time.
@sijo_animech - so sorry about it.
We’ve just released a fix to the shading type issue. The shading type is no longer exposed in the Editor, and Physical material is always used by the engine. So this hopefully solves some of the issues.
Regarding the lost tint color values - please check the console to see if the details are logged there.
If you have reloaded your tab since then, click on the history:
Hopefully the original values are there at least.
Apologies for the reset with the latest release - this bug has now been patched. I can help assist you in restoring your material properties.
