Render Texture not tiling - Wrap Mode Issue?

Not sure what's happening...

Can't seem to get my render texture to tile no matter what the wrap settings, is this a bug or a feature?

 

It worked in the past for me. So either an issue with the unity version you use or specific to your project. Can you reproduce this issue in a new project? If so I would submit a bug report as it seems to be an unity bug. If it reproduce in your project only, it's probably related to something in your project.

 

Yeah, I tried it in a new project, different version, and see the same behavior.

 

In what situation? Can you show how you're using it?

I found in some situations Unity will not actually provide the original render texture, but instead a temporary copy which does not have filtering or wrapping settings copied. The only solution I found to this (apart from significant refactoring of the code to avoid this hidden copy) was to use an inline sampler state.

 

Ah, thank you for the lead. I'm relatively new to Unity and will have to research to know what an "inline sampler state" is or how to have it tile the texture.

This seems to occur with any render texture.

I just found out that setting the Anti-Aliasing to 2 or higher on the texture is a work around for this Wrap Mode issue.
This sucks as I don't need to Anti-Alias my mp4 and I'm worried about the performance on the Oculus Go. :-/ I guess I'll report the issue for now.


I've tried this in Unity 2018.3.4 and 2018.3.6

 

Another note: Setting the Render Texture Depth Buffer to 'no depth buffer' also fixes the wrap mode.
And on an unrelated note: in the Lightweight Pipeline the Render Textures only filtered in point filtering in the Android builds. Not suitable for my VR project unfortunately, I'll miss using the shader graph.

 

This is on the Oculus Go. I'm doing an mp4 > video player > RT > material on a mesh. Color format - ARGB32.
With the standard pipeline it works perfectly. On the lightweight it has only given me point filtering.

 

Will do!

 

Thank you so much for this thread. I have been trying to use 2018.3.6f1 on a project I last used with Unity 5. It has worked through Unity 3, 4 and 5, but now my rendertextures were ignoring TextureWrapMode.Repeat and were acting as though they were clamped. When I changed the depth buffer from 24 to 0 as you suggested it worked again. This is not how I wanted to spend the last two days and my brain was becoming clogged with this problem! I'll see if there was any reason the depth buffer needed to be 24, but just seeing these things tiling properly again is a relief.

My current target is the Mac, but I too am intending to port to the Oculus Go.

 

Same problem in 2019.1.3, It works if you create a custom render texture

 

Unity staff asked users to submit a bug-report in this thread already, but it seems nobody did so far. Please submit a bug-report as described in this document:
https://unity3d.com/unity/qa/bug-reporting

It's important that you report these issues together with a reproduction project if you want them to get fixed. If you don't do it, it might be a long time until someone else reports them or until Unity Technologies find them.

After you submitted the bug-report, you receive a confirmation email with a bug-report Case number. Please post the Case number (number only, not the link) in this forum thread for Unity staff to pick up.

 

I have the same issue, wrap mode set to repeat doesn't repeat the rendered texture for me as well. On older versions of unity it worked flawlessly (unity 5.6..) now I am using the unity 2019.1.10f1 version.
I don't want to have Anti-Aliasing activated and also i need the depth buffer to work in repeat mode properly.

Is there already a solution or a workaround?

 

I reported this issue to unity in a sample project, I hope they will fix this issue very soon. I rely on this function of the render texture.

RawImage settings (Should tile the rendertexture 3 times on x-axis):


Rendertexture WrapMode set to clamp:


The result:
you can only see one rect:


Rendertexture WrapMode set to Repeat:


The result:
you can still only see one rect:

 

Rendertexture WrapMode set to Repeat And Anti-Aliasing to 2 Samples:


The result:
you can see three rects, like it also should show without anti-aliasing turned on:

 

Same bug found here. Worked in 2018.2.2. Upgraded to 2019.2.5 and now it doesn't work. RenderTextures are stuck in clamp mode.

The antiAliasing solution isn't good for me, because it stops mipmaps from working. But setting depth to 0 works.

I had no idea that RenderTextures stored a depth buffer as well. Seems like that should be off by default!

I couldn't find this issue in Unity's issue tracker though, at https://issuetracker.unity3d.com/

Annoyingly I couldn't find a way to match all words when searching, which is far more useful than matching ANY word (means when entering more words, the search becomes more vague rather than more precise).

 

you can be able that if set to "No Depth Buffer" of RenderTexture options.

 

This is still an issue in 2019.2.13. Couldn't find the bug on the bugtracker.

 

Thank you this solved my problem I think. Well it works in Editor

 

Is this still a bug because my render textures are not wrapping after moving from 2018 to 2019 on some platforms?(opengl 2 mobile)

 

Still a damn bug in 2019.4.13f1. Confirmed setting the depth buffer to No depth fixes it. @HECer can you post a link to the bug report you made?

 

Any chance you'd be willing to enumerate some of the situations in which you've seen this occur? This appears to be happening to me right now, and while the inline sampler state workaround works perfectly (thank you for that info btw), I'd like to know if this is happening because of something I'm doing, and whether it would be worthwhile at this relatively early point to engage in "significant refactoring of the code to avoid this hidden copy".

 

hmm the thing is you may need a depth buffer to render what you want into the render texture, but afterwards it is used as a texture and can wrap.
You can use a temp rendertexture if in code, and copy contents to a texture2d after but this is still clunky (not sure why no CopyRendertextureToTexture() type function as ReadPixels just seems slow and awkward).

 

Thanks very much for the insight.

 

Interesting! I had thought that I had the depth buffer disabled, but I guess I'll have to double check when I get back. I'm certainly not using any depth buffers for what I'm doing...

[Edited to Add] Definitely no depth buffer enabled. Bummer, I had hoped that would be an easy fix ;-)

 

My render texture has the exact same quirks. I remember setting the anti aliasing, cause i thought it would be nice for my render texture, when i made it. But i got an error in the console, that said anti aliasing wasn't supported. I then naturally turned it off, without know that would make my texture always clamp, no matter the wrap settings.

 

Unsure if this is the same issue, but I was making a copy of a RenderTexture in my Assets folder. Every time it created a new one as a copy, it would lose the `Repeat` setting. Had to explicitly set it in code.

_rts[i].wrapMode = TextureWrapMode.Repeat;

Hope this helps someone stuck in the same boat.

 

I'm having almost the same issue on 2022.2.0b15.
Mirror mode works as clamp. Changing AA and depth values have no effect.
Repeat mode works.
