im having trouble activating path tracing on twinmotion 2023.1 preview.
it says to activate DX12 to enable path tracing but it is already activated by default , so i dont understand what else to do
the previous build i could use path tracing without issues
GPU is GTX1080 8gb
windows 10 pro
am i lacking in the hardware department ?
Hello,
Due to instability issues with Nvidia's GTX series cards with DirectX Raytracing (DXR), official support for this feature was removed from Unreal Engine 5.0.3. Since Twinmotion 2023.1 Preview 1 now runs on this version of Unreal Engine, Path Tracer can no longer be supported on GTX series cards.

What can I do_
hi there ,does TM work work with a graphics card of 6gb and rtx 3060 with path tracing thankyou
Hi
I have RTX 3050 on my system but I can't make path tracer work pls help
Hi ,
Which graphics card does your computer have? If your computer does not have a compatible graphics card (NVIDIA RTX or AMD Radeon RX 6000 series or newer) you won't be able to run Path Tracer in Twinmotion 2023.1.
If the graphics card is an NVIDIA GeForce GTX 10-series or Quadro P-series graphics card, it should be able to run Path Tracer in Twinmotion 2022.

Thank you,
Since you have an NVIDIA GeForce GTX graphics card, you won't be able to use Path Tracer in Twinmotion 2023.1.
Path Tracer on GTX graphics cards is only supported in Twinmotion 2022 on the 10-series graphics cards.

Hello,
I have NVidia Quadro M4000 and Path Tracer button remains unavailable for me.
I've just updated my PC accordint to the specs posted on your website, but I still have Path Tracer unavailable.
How can I make it work?
and I can't do anything about it?
HI ,
Unfortunately, the Quadro M4000 graphics card does not have any raytracing support and will not be able to run Path Tracer. You will need an RTX graphics card for Path Tracer to be able to work.

Hi ,
This limitation that prevents GTX graphics cards from using Path Tracer in Twinmotion 2023.1 is built into Unreal Engine 5.1 and we cannot change it. Unfortunately, this means you will need to upgrade your graphics card or you can continue using Twinmotion 2022 for Path Tracer.

Well, then we have a serious problem. Why won't Twinmotion write all these specifics directly on specs page on its website, so people don't buy graphic cards that are not ok to work with Path Tracer?
I've looked that page 1000 times before ordering a new hardware for my office PC, and I found NO WORD about Quadro graphic cards incompatibility with Path Tracer function. Perhaps, it's a known issue among hardware specialists, but the software is made for people working in visualisation, isnt' it? So I should be able to consult all the necessary info on the specs page and according to these info choose a machine that will be able to make it work.
It's a very serious oversight on the part of the Twinmotion team. Sorry that I had to learn that by searching on forum and not on the specs page!
Hi ,
Our apologies for the confusion. The hardware and software specs page indicates in the Path Tracer Requirements section you will need a graphics card that is from the NVIDIA RTX 2000 series or newer. The Quadro M4000 is a graphics card that is older than the RTX series, and as such is not compatible with raytracing functions. Not all Quadro graphics cards are incompatible with Path Tracer, however. Any Quadro RTX graphics card should be able to run Path Tracer.
I hope this helps clarify.

Hi ,
The RTX 3060 6GB graphics card is compatible with Path Tracer. Just be aware that since it only has 6GB and not the recommended 8GB of VRAM you may need to manually enable DirectX 12 in the Edit > Preferences > Graphics Hardware Support menu, and your GPU may also be more prone to crashing in more demanding scenes when enabling Path Tracer.

Hello ,
The RTX 3050 should support Path Tracer. Please make sure that Windows is up-to-date and that inside Twinmotion's Preferences > Graphics Hardware Support setting that DirectX12 is enabled.
If you are having issues, please contact support at https://twinmotionhelp.epicgames.com/s/case-community-page and include a copy of your computer's DxDiag report and copy of your Twinmotion.log file (Where to find Twinmotion .log file).

Nvidia T1000 8GB or Nvidia Quadro Rtx 3000 6gb LP? Any of these would work with the last pathtracer? And which one of the two would be a better fit? Thank you!
Hi ,
Both of these cards should be capable of running Path Tracer, although we haven't tested these ourselves to see if they perform well, and which would perform better.

Hi,
I have a NVIDIA T1000 8GB and I am not able to activate the Path Tracer, even if the Directx 12 is activated. I have this problem for both the 2023.2.4 and 2024.1 versions.
Do you have any suggestion to solve this problem?
Thank you,
Marco
I have RX6800 and ryzen 9 5900x, however twinmotion says that i do not have the recommended requirements to run path tracer. Please help me fix this. Thankyou.
