AccuRender nXt

advanced rendering for AutoCAD

I just saw your newsletter on IES Patterns, etc. Can I use them with AutoCAD?

I am attaching a ZIP file of the 30 IES patterns.

You should be able to unzip these and use them, or any manufacturer IES files from the web with nXt Render. Here are 6 of the 30 patterns.

Here is a link to images of the 30 patterns. For many situations, one of these patterns may be ideal:

To use IES lights with nXtRender, follow these instructions:

Use the following steps to attach an IES file distribution to a light source:

  • Create the light in the usual way.
  • Right click on the light in the list and select Properties... from the menu
  • Change the Light Pattern to Goniometry File
  • Click the Browse... button and select the .ies file.
  • Normally you will want to use the file to define the intensity of the source as well. Click the From File checkbox under Brightness to do this.

Can I create a new custom light fixture block that I can attach IES info from a manufacturer to?

You should be able to assign the IES light to a light in a block, save it away, and use it in other drawings.

"0295 is up, includes scale factor for preview image and stop after # passes.  Haven't gotten to New light channel option in Lights interface yet.  Check it out if you have a chance (no worries if not.)"

"Yeah-- I understand.  I just think you may find you have a similar problem in this new engine with trying to estimate how many passes will be good enough.   That can vary a lot. You're always going have some error, allocating…"

"The problem is when I'm running several renders over a weekend. How will I know how much time to allocate to each one? I wouldn't want them to run for the same amount of time, as one may over-cook to no extra benefit, while another is…"

"It's an easy feature to add, but I'm pretty sure with this new version you'll find a time constraint to be more reliable.  The rendering below is probably done already, with a noise filter, or close to it."

Peter Milner replied to Roy Hirshkowitz's discussion AccuRender Studio
"I suspect it will take a lot longer without the noise filter. These similar renders ran for 5 minutes each. nXt performed 127 passes and Studio performed 344 passes. Incidentally, is it possible to set a render running to a certain number of…"

"Pretty much the only thing sacrificed has been the sandpaper bump, and even then only in certain circumstances.  Everything else is preserved nicely including any random noise you add to color maps. Hard to say on performance without the…"
