AccuRender nXt

advanced rendering for AutoCAD

Starting a new thread-- the old one is getting a little crowded.

Here's Jan's with e2 at 30 minutes, 300k pixels.  Daylighting only with all settings returned to default.  Obviously glow from the tv is still present.  I fiddled with the floor a little-- very low sharpness levels are undercounting fresnel reflectivity with this engine-- that accounts for the missing reflections in some glossy materials.  So I raised the Sharpness to 0.15 and to compensate lowered the Fresnel to 0.2.  This one still has a bit of mottling on some of the diffuse surfaces, but it's on its way.

Here's a path tracing-- the floor is different and it's only run for 15 minutes so don't try too many direct comparisons.  I haven't a clue why the saturation is so low-- pretty sure this is a bug. The e2 engine certainly has the colors more correct.  The Path Tracer is competitive with the e2 engine in performance for this particular scene-- probably due to the very large window area and many glossy materials.

Thanks Marc-- I won't be able to investigate this until next week.  I'm pretty sure I haven't implemented Alpha objects in this one-- although it should still render.  If you don't have any objects at all other than the ground plane it probably won't render.

ACAD2012,NXT E2 ,490PASS,

The sun did not cast to the floor, and I have adjusted illuminate Angle and height, but my window is a very small (600 mm), and no glass set.THANKS

Hi Roy, I'm trying to render a panorama with the new 294/e2 but both 4000 px widht and 2000 px widht crashes.

Hi all! As suggested by Roy, I've run a test at 300000 pixel. This is the result: engine 2, build 294, 6199 passes, 19 hours rendering. There are still some little artifacts on the floor in the foreground and only few of the LED lights appear correct. The glass of the bottle doesn't look really transparent, but it could be due to bad transparency settings in the material.

the transparency setting is definitely different from PT.  I'm still struggling to get it right. Is that the pink floyd pig in the air?

You're right Jan, transparency settings make me suffer much more now. And yes, that's Algie!

Hi Miguel, could you share Algie, please, I need it for my job... Thx

094 E2 click render buttons, AutoCAD automatic exit, this is the reason why?

"I think that for that type is better to use displacement map. Displacement actually modifies the geometry rather then just fake the relief."

Bump map for material

I want to create multiple materials with different bump maps, so that they can be assigned to the objects in AutoCAD for rendering. Please see the attachment for an idea. The idea is to assign the appropriate one to the object for rendering.If this can be achieved, it will avoid a whole lot of symbol creation, since right now to get the design etching, we are creating individual symbols for each design. Obviously this is very time consuming and results in literally thousands of DWG files, one…See More
