.. is Path Tracer works for animation video rendering ?

You can, but I would not do that. The end result is really noisy due to the denoiser giving different results each fraom that it renders, and the time it takes would be very substantial.

Are they denoised? Some people don't like the denoiser because it can remove detail. Without denoiser, lower sample will give you a grainy image, larger sample numbers, a cleaner image without detail loss.

Mxmillo, Thanks for commenting. Yes, the denoiser was on for all of the shots. The Anti Aliasing was set to its lowest level too, so the images should be sharper than the default (I think thats what most people use). Hopefully the only variable was the bounce settings and Path amounts.

What do you think , can I use default v-ray lights in Twinmotion without compromising "realism"? O r should i always go for the presets that are available in Twinmotion ?

Hi there. I do not think Vray lights will transfer to TM. They are different engines and software. My suggestion is send the model over, and do all your lighting in TM. Please be aware that the latest versions of TM have made changes to the lighting system (The use of Lux). This has made TM a little harder to use in my opinion, but the results can be stunning.

hello, In this evening test comparing standard high level 256 spp/deinterlace 1 versus custom 2048 spp/deinterlace 1, both denoiser on, the 2048 version keeps many sharpened details, that will not display in the standard render mode. But it took 14 minutes to render with 2048 spp. But I think that it is what I would choose for a final render. For animation, there is no doubt that rasterized standard mode is fast : I tryied a 20 seconds pathtracer on clip that took 13 hours on my machine.... what is regrettable with twinmotion is that you cannot adjust the denoising level. The denoiser that I don't use with vray is a massive image destruction tool!

13 hours? Wow. Right now, I use D5 for video, and use TM for interiors. The denoiser does need to be refined going forward, as video is very messy right now.

My apologies for the late reply to this question. Were you able to find a solution? I have not encountered this issue, but my thoughts would be the underlying geometry may not be perfectly straight/not built correctly. I have had a lot of success with TM support though, it could be worth reaching out to them.

You speak to bounce like it should accumulate and be brighter, but it’s probably about accuracy, or nuance.
@viarender
Жыл бұрын
Doug, Thanks for commenting. In my understanding, Bounces lead to indirect Global Illumination, as per a traditional ray traced system. Path tracing systems work almost identically to Ray tracing systems. Bounces should reduce shadows in the scene, adding more exposure and 'Light'. For accuracy or nuance, the Samples amount is the value that matters more. I am not a programmer though, so I could be totally wrong on this.

More bounces don't make the image brighter because more bounces doesn't mean more light. The higher the bounce value the more accurate the lighting will look but the image will only go as bright as the light you're giving it.
@viarender
Жыл бұрын
@Sandesh Bhandari, Thanks for commenting! As far as I know, 'bounces' determine how often light bounces from object to object. This is how Global Illumination works. Each bounce leaves color information on the surfaces it interacts with, hence 'Indirect Lighting'. I am assuming that this should result in a brighter image overall, and it does in the Path Tracer. In the video Bounce of 1 was dark, Bounce of 4 Lighter. No other light was added. Now 'quality' in the Path Tracer is determined by the Samples (Ray and Path Tracers are almost identical in this way, " (Pathtracer)...the algorithm only traces the most likely path for the light www.techspot.com/article/2485-path-tracing-vs-ray-tracing/). What was interesting here was the diminishing returns of going above 4 Bounces!

@@skystink Have you tried cranking the brightness of the HDRI way high? Between 4 and 20 (really, that high)? It doesnt blow out the sky image, as you'd expect, but it really adds light to the scene.
@don_specialfx2632

@@skystink I used to have this issue. But I found a convenient hack around this: (1) enable HDRI lighting and crank up its intensity. (2) depending on how your scene was modeled and or imported, sometimes u can hide an external wall that is not captured within the shot you're about to render. Hide wall, update view to allow more natural light in. (3) increase exposure ever so slightly. (4) introduce other lighting and adjust color or temperature to match that of the sun. (5) increase or lower sun intensity depends on what u seek to achieve. (6) increase ambient lighting.

@viarender
Жыл бұрын
@eastudio, Thanks for asking. So, there is no fix for this yet. Rendering a single second of video is basically 24 -30 frames a second. Each frame is one complete path tracer render... so its costly to do even 15 seconds of video. I would try: Lower the video resolution to 1024, lower the path tracer settings to the lowest you can tolerate (which is pretty low), render smaller clips with less camera movement, use a video AI Upscaler to increase the resolution to 2K. Make sure there are as few lights in the scene, and try to keep the scene as 'light' as possible. Lastly, remember, your clients are not visualization experts, and the general public is very impressed by any type of animation, so dont hold the content to your standards, but to that of a non 3D artist.

I have been trying to replicate your tutorials and was wondering have you or did you compared the PT effects in the version of TM you demoed in the tutorial and the current PT in the latest version, 2023.1.2? They seem to me to behave very differently with the same model and settings, maybe its my machine don't know, but looking forward to many more of your splendid tutorials on TM. Thanks for the help and lessons and for taking the time to produce such great content.
