Problems with rendering

[Anonymous]

Work in autocad architecture, and when performing a render, deforms the walls and does not show the shadows.

Open changed some variable, maybe?

I confirm the issue here.  Autodesk made some horrible decisions when they transitioned to the current rendering engine in 2017.  Even the cloud render of this scene is fraught with errors.  See here:  https://gallery.autodesk.com/a360rendering/projects/dibujo2.  It is much better than the desktop results but still poor.  Would anyone pay for such results?  I think not.

It is extremely disappointing that the gallery does not even recognize AutoCAD Architecture as a source program for the render.

thank you very much

Run the render on ACA 2015 from the same file and the result is perfect.

I agree.  Autodesk are you recognizing this problem? Give us back a rendering engine that actually works in the next version and fix the problems in 2016 and 2017.

I took a look at that file and it appears that you were tinkering with a lot of different settings that ended up producing really poor rendering results.  I attempted to figure out what went wrong by checking "lightingunits" and "defaultlighting" but despite fixing those settings, the rendering output was terrible.  I'm not sure what is off in the file but I cut and pasted the objects into a clean file to produce the attached results.  Shot 1 = one simple target light with intensity factor adjusted as desired.  Shot 2 = turned on Sky Background and Illumination.  Shot 3 - Turned Off Single Light Source and Activated the Sun.  Shot 4 = Modified a few basic materials, changed angle of camera and some Sun settings.  Shot 5 - On this test I only used the default "Render for Dummies" settings found on the "RenderExposure" Palette and tinkered with Render Materials.

When models are imported as Surface Models you are likely to find all sorts of irritating problems like inverted face-normals, inability to assign materials to individual components and so on.  I show the Cobra model I picked up years ago to illustrate how there's no way to improve the faceting.

In short, you can produce good renderings in AutoCAD Architecture 2017 if you have good models and proper settings.

Hi @Anonymous,

The objects in the file are very far from the origin (0,0), which is causing the issue. They are at  approximately (367000, 7370000).

3D objects should be kept within 10,000 units of the origin, as a general rule. If you move the objects closer to the origin of the file, they render correctly.

Additionally, when a file is created in a version prior to the render engine change (2016 and later), you may need to adjust the lighting and materials to achieve similar results in the new engine, as it processes the settings differently. For more information about the differences and how to adjust for them, see this article.

EDIT: I looked into this a bit further, and found that it's already been reported to the development team as well. I've linked your Technical Support case to it to demonstrate the interest in having the new render engine enhanced to allow this.

Please go back to older rendering.  So many frustrating things in cloud render that I am changing to a competitor's program.  I really hope that you will take this seriously because 2016 rendering was fantastic and now we cannot make productive work with anymore.
