Hi all. I have experienced a problem with a a wood texture as per the attached video and photos that shows "patches". Anyone has any idea what is causing this? Additionally as you can see there is flickering in the video. What should I change to reduce or eliminate the flickering fully? (Ignore the fact that furniture overlap each other, silly mistake)
Hi ,
Regarding that material inconsistency issue you're seeing, some materials don't behave well with Path Tracer if the two-sided property is either enabled or disabled. Try switching this setting for the material on or off to see if that helps. If that doesn't, we would need to see a copy of the Twinmotion file to get a better understanding. If you could submit a bug report here and upload a copy of the Twinmotion file, that would be very helpful. Make sure to compress your file using the Resource Collector in Twinmotion's Edit menu to preserve texture data when sharing.
The flickering you're seeing is a result of the denoiser that Twinmotion uses for the Path Tracer. Those are artifacts left by the denoiser when it removes Path Tracer's noise. Unfortunately, the denoiser is much less effective for videos than it is for static images, resulting in the flickering and warped parts of the video. The team is working on improvements for this.
For now, third part denoisers, such as Neat Denoiser, Davinci Resolve or Adobe Premiere's denoising tools tend to give better results. If possible, we recommend exporting your video with the denoiser disabled, then using one of these third-party tools to denoise. If a third-party tool isn't an option, then you can increase the number of samples per pixel in your Twinmotion Path Tracer settings, but just be aware that it may take a very large number of samples to eliminate this effect, which will increase render times proportionally.
Best,
