AccuRender nXt

advanced rendering for AutoCAD

Hola Roy, en diciembre adquiri mi licencia full version de Nxt estoy tratando de establecer los settins para el render interior de esta cocina pero cuando trato de renderizar el sistema se torna lento apenas llega a 6 pases en 40 minutos. Yo he creado varios materiales en desplazamiento como lo es el piso y los mosaicos para la cocina, no se si esto tiene que ver. Mi sistema es Windows XP Sp3, AMD Athlon (tm) 64X2 Dual Core 4200+2.21 GHz, 3.00 gb of RAM. No se si es problema del sistema o no estoy procediendo bien con los ajustes.

6 passes in 40 minutes is not bad.

The more lights and reflective finishes the longer the render times. Materials with displacement have a big impact on render times. Do not use displacement unless necessary.

Chas has the right idea.  There's obviously something bad happening on the ceiling-- I don't think your pendant light sources are working properly and they may be contributing to the problem.  Tag surfaces as glossy whenever possible.  Avoid Monte-Carlo reflection.


If you want to leave in all of the reflectivity and material effects-- I would strongly suggest using the Path Tracer engine.  It won't be affected as much by displacement, reflectivity, etc..-- although it may take a while to remove all of the noise.


I'd be happy to take a look at the model if you wish-- I may be able to offer some more suggestions.  It can be uploaded here.



Never knew path tracer is not affected by displacement. Will give more try to path tracer from now on. What other effects are not affected by path tracer?
It's been mentioned many times here.  The path tracer is slowed by displacement maps, just not as much.  Plants will also not affect the path tracer as much.
Just so I get this, if packet tracer takes 2 minute to render a plant path tracer will take less, right? Same applies for displacement, right?

Roy, I change the pendant light that i use from Ar4 and look better, I also send you the model for your revisions.



Rey, the model has a few big problems.  

You're correct in your suspicion of the displacement maps.  This is clearly not a good application for these.  A simple bump map will suffice and will render much more quickly.  Use displacements sparingly, and only when you can tell the difference. 

There's also some nasty units problem going on here.  The model is displayed in feet and inches by the INSUNITS are not set (0).  This will cause nXt's units to default to meters.  It's not very important to the appearance of your image, but it does mean that the lighting data is off by a factor of 39.  This will make it difficult for you to do things like combine daylighting and artificial lighting.  When I changed the INSUNITS to inches (1), the lighting data came out correct, but the texture maps were incorrectly scaled.  

I'll take another crack at this tomorrow or later tonight if I have time.

Roy I make the correct changes and i think that every thing was fine now. I work in the final model and let you konow wen it is finish. All your points are correct...


Thanks a lot.



Another thing to try sould be to turn up the brightness in the render window dialog. You then may have to turn down some of the downlighting.

"Those are all exceptional work, Peter! Congratulations!On this one only: bricks look big to me, but maybe I am wrong. Also some areas in shadow look still a bit noisy."

"1-  On the Rendering Tab there is a popdown called Destination.  The option is called something like "Local Out of Process".  2-  No, installation will require admin access."

"Yep-- the groundplane in ArStudio should be turned on in that case-- but you will get a rectangle which may need to be sized.  If it's not turning on, that's probably a bug."

"Not to worry. I've just seen that ArStudio has its own version of a ground plane. It just doesn't translate the old nXt one."
