Rendering problems

[Anonymous]

Hi everyone,

I am trying to render an .ipt file on the normal render environment on inventor 2016 but the image keeps coming out very grainy even though I have tried different widths and heights etc. Is there any way that I could get a better quality image?

In Inventor studio?

or via raytracing in the part environment?

If studio have you adjusted the Image Filtering (antialiasing) on the Renderer tab of the render image dialog?

If raytracing have you turned it to high quality?

Have you tried to adjust lighting? 

Please post an image that you are rendering showing the grain.. and answer the questions above please

mcgyvr,

Thanks for the reply. I am working in Inventor Studio. I have tried adjusting the antialiasing (type and width), but I am not entirely sure what I am adjusting here. I have tried various combinations but the iamge is still pretty grainy. Please have a look at my image to see what I mean. Also what would you say the the best configuration of lighting and reflections/shadows is?

are you letting it render past 32 reiterations ? 

set it to until satisfactory .

Yes see the post from mdavis above.. You just need to let it render longer.. Each pass will reduce "grain" size further and further..

There is no best configuration of lighting/shadows.. There are too many variables to recommend any that work well IMO..

You just need to keep playing around with all the settings until you are happy..

When a new version of Inventor comes out I typically spend a day or 2 just adjusting materials/lighting,etc.. to achieve the results I want. Autodesk is always making changes each year..

YUP ..... drives me NUTS!    Glass was a horror to a decent rendering level .. going from 15 to 16 ....

Brilliant, thanks for the help, it works, although im going to have to wait a few hours to get a decent render! Those youtube videos are awesome, thanks for them, I have just sat and watched them all!

Check out the Friday Pictures post that (usually) Neil post ever Friday  ....

you can see a lot of rendering there. I'm sure anyone of those posting would answer rendering questions that you might have

Thanks Michael

I don't do a lot of rendering so I'm looking for some advice.  Marketing requested a large, high DPI rendering.  I set it to create a 4000 pixel wide image at 200 dpi and to run until satisfactory.  It has been running for 48 hours now and completed 11,328 iterations.  The image I see looks great (and has for quite some time).

My question is:

With the run until satisfactory setting, will it eventually decide it has completed the rendering?  Or is it waiting for me to be satisfied?  This far in, I'm hesitant to click the pause button and the save button is greyed out.  

Is there a way to save the current progress?  Or must I wait for it to complete before I am allowed to save?

The till satisfied will go till you stop it. I've done it overnight to see how it far it'd good..

Added a few examples:

Yes, you can stop it at any point save it ...continue
