Support for nVidia's RTX in Local Rendering

Pedro_Bidarra — Sat, 16 Mar 2019 14:54:57 GMT

Hello,

I would like to know if Autodesk plans to accelerate local rendering using the built-in GPU raytracing capabilities of the new RTX cards (via DirectX12 on Windows?) and when can we expect it being implemented?

I order a new desktop at work with an RTX card, because other programs I use like Adobe Dimension already take advantage of it but I'm really hoping Fusion 360 will take advantage of GPU raytracing.

No one from Autodesk wants to comment on this?

I feel like pressuring Autodesk on answering this.

I'd also like to hear something from the AD team about this.

Chiming in, I'd also like to know

The short answer here is no - the local render uses your CPU.

Before anyone asks - i'm not sure why. Probably stability and resources. Now i wish it used the RTX or other cards as well and if you want that, i'd post it or vote for it on the idea station.

@ryan.bales , thank you, there is an idea on ideastation that kind of goes in that direction but it's not exactly what we are asking for: https://forums.autodesk.com/t5/fusion-360-ideastation/directx-12-raytracing-dxr/idi-p/8225591

I would certainly vote for such idea if you care to post, I would only ask that you reply to this thread with the link for us to vote on it.

Yes, the rendering is all CPU (currently) because raytracing was not a feature available on GPUs, but with Direct X 12 DXR and RTX GPUs even applications that were CPU only rendering like Keyshot or Adobe Dimension have support for DXR/RTX in their pipelines for this year.

The idea station is really meant for you all. I'd be happy to vote for one - but i try to avoid posting ideas on there.

I agree it would be worthwhile and it might be something they are considering if/when DX12 API is supported in Fusion.

@ryan.bales - Has anything changed over the past two years?

Also, I was wondering why Ray tracing wasn't possible on my old GTX650, but it is possible now I got the RTX2060, even though Fusion doesn't seem to use my GPU for rendering anyway. Some explanation would be very much appreciated 🙂

Nope, nothing has changed on this front. Its more widely known that rendering uses multi-core/multi-thread than it was then. I do not see rendering in Fusion changing to use video cards any time soon and i'm not aware of any plans to do so.

Hi,

Take a look at this comparison, even if it is not the content of the question.

Disappointing.

Probably to force you to pay cloud rendering. This is a cheap move from Fusion 360
The more you implement things and make them accessible the more you win, Autodesk. About time you took note of that. CPU takes all the load, no wonder Fusion is unstable. Has so much potential tho

The render engine employed by Fusion 360 is LAGOA. The company was acquired by Autodesk in 2014 (2 years after it was founded) and the product integrated into Fusion 360. The are a number of easily accessible online resources that reported this.

Here's a Linkedin Profile

Lagoa was implemented as a cloud render solution running on "normal" CPU's. That cloud render solution allows people without high end hardware to create nice renders. That also made it very suitable for integrating it into Fusion 360 and ahs worked well for may people.

Assuming that there is "Ill will" on Autodesks side is absolutely ridiculous. Getting a CPU based render engine to run on a GPU is a complete re-write as the architecture of modern GPUs is completely different from a CPU. There are simply bigger fish to fry at the moment.

I have worked with CAD software for over 3 decades professionally and 20+ years of it in 3D. I work with Fusion 360 every day in a professional environment and on my private projects and I don't see instabilities.
