Archviz textures and video flickering unwanted!

anonymous_user_6096f04f · September 30, 2015, 2:34am

Please watch in HD. On the left at the floor lamp, on the sofa and on some of the chrome I am getting odd flickering which is really annoying - don’t think I could hand work like this in to a client. Anyone know what the issue is? I exported as a jpeg sequence with Matinee.

Thanks.

Hi RI3DVIZ -

There may be another issue here, but if you could please render out a PNG or BMP sequence. These file formats use less compression than the JPEG file format which can may eliminate some of the artifacts and flickering you are seeing. If you can do that and share the movie then we can see what else we can do to help you out.

Thank You

Hi Eric,

The flickering is present when I preview the matinee sequence in UE4 prior to export, I don’t think it’s an export to jpeg issue.

Eric,

It mainly happens on fabric textures if that helps. I’m using jpeg textures found on the web that are seamless.

This is with png export and adjusted fabric texture. Still some issues around the left floor lamp and on the fabric.

Hi RI3DVIZ -

OK it looks like you might be getting a moire pattern off the fabric with the temporal aa and the moving camera. Can you post a screenshot of your material for the couch and the post process settings that you are using in your level? For the lamp I am thinking it might be some AO jumping in trying to calculate around the thin bar in the lamp. What types of lighting are you using as well? Honestly, this looks like some settings just need to be adjusted slightly you are very close, if you want me to take an indepth look you can link me the project via the Private Message system on the forums as well, otherwise the screenshots mentioned above will be fine.

Thank You

Here’s a few, please let me know if you need others. Specifically what in the post process volume settings.

Thanks!

Hi RI3DVIZ -

Well everything looks ok except your AntiAliasing. Can you bring up your Output Log in the Editor (Window >> Developer Tools >> Output Log) and type in the following command r.PostProcessAAQuality ? and let me know what your setting is listed as. You should get somethign along the line of this:

HELP for 'r.PostProcessAAQuality':
Defines the postprocess anti aliasing method which allows to adjust for quality or performance.
 0:off, 1:very low (faster FXAA), 2:low (FXAA), 3:medium (faster TemporalAA), 4:high (default TemporalAA), 5:very high, 6:max
r.PostProcessAAQuality = "4"      LastSetBy: Scalability

Thank You

This is what I got after typing the command and hitting enter:
Cmd: r.PostProcessAAQuality
r.PostProcessAAQuality = “4” LastSetBy: Scalability
LogD3D11RHI: InitD3DDevice
LogD3D11RHI: InitD3DDevice
Cmd: r.PostProcessAAQuality
r.PostProcessAAQuality = “4” LastSetBy: Scalability

I’m working on another test scene and the problem is worse, I have attached the texture - it goes on the side of a building and flickers like crazy!

Hi RI3DVIZ -

It looks like you textures are not power of two (512x512, 1024x1024, 2048x2048, etc.). This means the engine is not creating mip values for your texture and using the aliasing to soften transitions based on camera distance. Try adjusting the texture to a power of two value and see if your flickering decreases.

I will note that using any regular pattern which is tiled very small will cause some moire effect, but correcting the power of two texture will help eliminate some of the extreme fuzziness generated in your level and should give you some really nice results.

Thank You

Hi Eric,

Thanks for the reply but this is not resolved.

I’ll try that for the textures but it still doesn’t solve the flickering around the floor lamp. That is not texture related. In addition I made my texture to the power of 2, the wood siding and it still flickers extremely bad!

Hi Ri3DVIZ -

It looks like this is a debugging issue that I will not be able to assist further with unless I have the project in front of me to debug. You are welcome to link me a copy of the project via the Forums’ private message system, here

Thank You

Hi Erik,

Okay I’ll send the project. How do I go about making sure you get the entire thing as I’m new to Unreal and have never sent a project to someone.

Thanks!

Hi -

All you need to do is from Windows Explorer, zip your uproject file and the entire subdirectories of CONFIG and CONTENT with all files inside into a zip file. I will be able to open the project with no errors.

anonymous_user_6096f04f · October 6, 2015, 11:59pm

Eric,

It’s over 2 GB’s not sure I can send it. I’ll look for a way though this week.

Thanks.

Hi RI3DViz -

We have not heard from you in one week. Whenever you are able to post your project or link me here or via private message on the forums, feel free to reopen this question. Until then I am marking this as resolved for our tracking purposes.
