Hi Stephan, I’m using Text Mesh Pro preview.8 - 2.1.0
I’ve got a bug where I change text to “” (an empty string) but whatever text I had before still keeps being displayed. The inspector confirms that the text mesh component should be displaying an empty string… but it isn’t:
Setting the text to anything else that isn’t an empty string is fine.
Also, setting the text to " ", as in, a string containing a single space (to fake an empty string) works fine! This is my current workaround to set the string to be empty.
So, there’s some regression in this preview version when it comes to empty strings, because this was working fine in the last stable/not-preview version, before I moved on over.
Unhelpfully, I’m not entirely sure how to reproduce this, creating an empty scene and changing a TextMeshPro component in a script to have an empty string doesn’t cause the issue. And I don’t know why that is. Happy to give more information or try something if you have any ideas of anything to try.
I have encountered this too (it also can result in a completely incorrect visual result)
though I am still investigating exactly how to reproduce this one
We’re just setting .text directly but we do have some scaling on the parent objects and with some hacking I disabled that & it seems to fix the issue somehow.
The white text is the result of incorrect SDF Scale where in the case of the image above is close to a value of zero. This is likely the result of changing the scale of the text object which should always remain uniform in order to render correctly. It is fine to animate it but make sure at the end that x, y, z all end up the same.
The text becoming visible is likely a rounding issue which I should be addressed in Preview 9 but I would like to get some repro project to make sure I have caught all potential variants of this. The one repro project I had where this was happening was the resulting of rotating the RectTransform which in turn was causing a floating point rounding error in the lossyscale.
So if you can reproduce this issue please submit a bug report and provide me with the Case # as soon as you get it from Unity via email. I am planning on releasing Preview 9 within the next day or so and would love to verify this before then.
That white block text only appears when a previously-set label has been set to an empty string, however. Otherwise our scaling & animating works fine. I don’t know what is necessary to reproduce this bug so I doubt if I’ll have much success trying to create a project but I’ll try. My one guess is it’s related to scaling.
Thank you. I will take a look at it tomorrow since it is 2:00 am on my end and follow up as soon as I have more information. I am pretty confident I have already fixed this in Preview 9 but I’ll will confirm.
Just had a chance to take a closer at this issue and I should be able to include the fix in Preview 9 which I should be able to release over the weekend unless I run into any unforeseen issue in my testing.
It seems like those issues are resolved but I have a new issue with text not being visible at all in some cases. I’m trying to narrow it down.
It seems to be input fields mostly
Edit: It seems that when the text length is below a certain portion of the whole text field the actual text stops rendering. I cannot find a way to reproduce this in a sample project though.
Most likely related to the following [issue]( https://discussions.unity.com/t/760161 page-3#post-5749837) which is fixed in Preview 11 which should be available in 30 minutes or so.
