AccuRender nXt

advanced rendering for AutoCAD

I've just implemented Intel's denoising library in AccuRender Studio. I think the results are very exciting.  Most models seem to be something like 4-10 times faster(!).  I'm pretty darn sure this makes AccuRender Studio faster than the original Standard Engine, with much better results and much less monkeying around (no daylight sources, reflective shaders, etc.)

The Intel Open Image Denoise, unlike nVidia Optix (which I had previously implemented), does not require a specific GPU.  It runs on modern Intel CPUs and seems to be equally fast and perhaps a little better in quality.

You can get it on the Download->AccuRender Studio page.  Please note that I have changed the names of the AutoCAD plugins, so early adopters will have to repeat the netload command step.

I do have a relatively fast 16 core machine, however, this one ran for one minute(!):

This one ran for five minutes-- it's got a ways to go but this level of completion would have been hours and hours before.

More to come.

I've noticed that the material editor is missing Angular Blend.

Is this something that is to be added back in later?

No Angular Blend per se (it was never physically based and kind of wreaks havoc on some types of calculations.) However, any material with reflection will exhibit fresnel reflectivity which changes with viewing angle.

"Sort of-- nXt has a hard-coded max of 32 but you get diminishing returns before than point.  If you go beyond 32 they can sometimes be used, depending on the load.  I guess I would still think of 32 as a practical limit. ArStudio should…"

AccuRender

Purchased a new subscription to Autodesk. When I logged into Autodesk, it automatically upgraded my version I was using and installed 2021 version. Now my AccuRender NXT does not work nor will it load on 2021 version.I have spent the last 3 weeks trying to get support but I am not receiving anything.I have paid and downloaded the latest version of NXT but it's not working nor is the support working. Having been an NXT CUSTOMER for many years, I am extremely disappointed in the support.Not sure…See More

"Yeah-- like I mentioned the caustics are accurate but could be annoying.  Things that might alter it include changing the sun angle so it's not striking the chair's metal surfaces so directly, changing the roughness of the chair…"
