AccuRender nXt

advanced rendering for AutoCAD

We've been working with nXt Render Farmer for sometime now and have noticed some weird things. Initially we had little to no issues with it outside normal fine tuning issues. I have however noticed since our tech decided to restructure the architecture of our server that larger renderings will bounce from farm node to farm node on the farm monitor and any calculations to produce completion time estimations might as well get thrown out the window (sometimes the rendering never resolves period). Does anyone have any idea what could be causing this (I've suggested to tech that it was the restructuring of the server architecture but they simply disregard this as they are "infallible"). I was in a dialogue with another department about this and things did not resolve the best as I am held responsible for the on-goings of renderings and the render farm.

Probably a node crash.  If you can pin it down to a more specific model that's crashing we can try to test it to see if it's something at our end.

Will do what I can to see if I can isolate a model, I've got one drawing we were going to use in our digital catalog that ultimately has been bypassed due to it continually being problematic, I think it would be a good jumping off point for the isolation. File is too large to test as is, will keep you updated.

"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…"

"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."

"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…"

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

"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…"

"It's interesting-- overall the quality of this interior is very high for that 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…"

"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."
