AccuRender nXt

advanced rendering for AutoCAD

Starting a new thread...

Latest version of AccuRender Studio is here.  Among other changes:

  1. ArStudio command automatically loads the model and begins interactive rendering in addition to bringing up the Control Panel palette.
  2. Decal interface has been redone to include multiple decals and cylindrical projections.
  3. Legacy data is being handled a little better.

Here's a direct comparison between nXt Path Tracer and AR Studio.

Both ran for just under 2 hours.

ARDECAL doesn't seem to work.

I'll get a new one out today-- I think I know how to fix this.  Which image is which?

Top one is nXt.

Here is the link to the new one-- untested but hopefully ArDecal works.  When you get a chance try running the top image for a short time, say 10 minutes, and see what you get.

ARDECAL now works.

Here's the image after 10 minutes of rendering.

I do have a slight concern that reflective surfaces seem rather dull.

This is particularly evident on the end frame of the desk and the base of the chair.

It's interesting-- overall the quality of this interior is very high for the short amount of processing, and may be acceptable for certain scenes.  In this one, however, there are some reflective caustics that are taking longer to resolve.   You can see them clearly on the back wall, including the bright patch behind the chair and some more subtle ones.  They're much better resolved in the 2 hr. version. This is direct sunlight that's bouncing off of the metallic surfaces.  The spots are pretty bright so they're affecting the tone operator as well which has the net effect of "livening" up the metallic surfaces themselves.  These kind of effects are accurate, but may be annoying depending on your goals.

All of this, BTW, is missing in the nXt version.

You can see from these two images that there is definitely something wrong with reflective surfaces.

It appears the light is being reflected, but not objects or textures.

In the nXt version (top image), the carpet texture is being reflected in the drawer handles. This is missing from the Studio version (bottom image).

Placing a mirror on the back wall (reflections = 1.0, noise = 0.0), you can see the difference more clearly (top image is nXt).

Ah-- so that's a function of the material type.  The standard material won't give you a mirror anymore.  You need to change the material to metallic and you should get something more familiar.  Use the Type popdown on the material editor to change this.

Here's the latest render using metallic materials.

The chrome now looks a lot better.

I do feel though that the reflected light on the back wall is too bright.

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 surfaces, or turning down the sun a little or adding a window covering.

On another note-- the glass should be a Refractive material with the Thin box checked.  (It probably is already, just mentioning it because the Standard material is not appropriate for glass-- Standard materials with transparency will work for things like curtains.)

"Interesting.  ArStudio has its own WalkAbout-like feture, it's the little camera button.  If you do it while the preview is running you should see the view changes automatically in the rendering."

"I'm having trouble getting the desired view in Studio. I've tried setting the view in nXt walkabout and then using that to set the AutoCAD view. However, when I render from Studio, it gives me something different (see images below)."

"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…"
