Rendering Higher Quality Images

This is my second time attempting to post this question. Hopefully it decides to work this time...

 

I apologize in advance for the length of this post. I'm having issues with rendering images from Fusion 360. At least, I think I am since I'm not getting the results I expected. I have an enclosure with ten pieces of electronic equipment inside. I need to provide renders of the enclosure at different angles and zoomed different amounts. Here I'll post some examples of what I'm experiencing from one angle.

 

At first, I tried using the local in-canvas render. For small, single-piece items, I typically let it go 20-30 iterations. For these, I let it go more like 50-75 iterations. This worked okay for my client's immediate need. Okay, but not great. But then he also needed to be able to zoom in on the images and still be able to see the images and the wording in the images clearly. In the past, we weren't able to purchase cloud credits for cloud rendering, but apparently we can do that now. So I bought 100 credits, assuming that would resolve the issue. Well, it hasn't. Here I'll show some images that I've rendered.

 

These first three are the exact same view, rendered in different ways. For this first one, I used the Print cloud render setting of 5x7" 300PPI (3 cloud credits).

For this second one, I used the Print cloud render setting of 8.5x11" 300PPI (8 cloud credits).

For this third one, I used the local render at about 50 iterations (0 cloud credits).

Obviously, the first one is the lower quality, but it is really hard to see any difference between the other two. I honestly have a hard time deciding which one I like better. Yet one was free and the other one cost me $8. What's the point of paying for higher quality renders if I don't actually get a higher quality render?

 

Now for the issues with the zoomed-in images. Trying to zoom in on one of the above images results in a grainy image. This isn't really much of a surprise--I expected this.

So I tried zooming in on the model before rendering. I thought for sure this would fix the issue. Here's a screen shot of how exactly how I was zoomed before rendering.

When I rendered it using the cloud, this is what I get. You can see that it's zoomed differently than I had it set above.

And this is what I get when I crop this view to what I actually need. It's less grainy than doing a local render, but it's super blurry.

If I zoom in the same amount as above and do a local render, it turns out grainy and blurry.

Enclosure 4-3(2).png

 

The final requirement of my client is an image zoomed in to only showing one piece of equipment. Here's how I zoomed in before doing any renders.

When I rendered using the cloud, this is what I got. You can see again that it's zoomed out further than where I had it set when I told it to render.

Enclosure 4-4(2).png

 

This is what I got when I tried to do a local render.

For reference, here's one last image. This is a render that I did earlier of just one of these electronic pieces of equipment. This was done locally using no cloud credits, so I would have expected much better than this by paying for higher quality renders--not much worse.

I know there's a lot here and it's hard to read through it all. If you made it this far, thank you. It's really hard to write out and explain what's happened and what's going on. I know that it will be equally hard to respond coherently in a forum like this. If anyone has any direction on how to get better quality images out of this, that'd be great. If there's a moderator or a Fusion 360 customer assistant that has read this, maybe a call on the phone would be the way to go.

 

Thank you in advance to anyone willing to help.

I guess I didn't really say exactly what my questions are:

  • Why are cloud renders (that cost money) of equal or less quality than local renders?
  • What do I need to do to actually get better quality images?

Thank you.

Hi @karina.harper ,

I know it's the holidays right now, so not a huge rush, but I was wondering if you could take a look at this post and let me know what you think. I tried sending a message to Support, but I guess I don't have access to do that.

 

Thanks! Happy New Year!

Hey @brysonwhitedesign 

 

Sorry for the delay on this, I was out on vacation. I saw your other post as well - did the focus settings resolve this issue as well or are you still seeing a difference between cloud and local?

 

Cheers,

 

Karina

I had seen this and the other thread but forgot about it.

Did you try another lighting environment by any chance ?

 

In general it is not really that easy to make the flat front panels of such devices look interesting. There seem to be very few fillets that can provide highlights to help the eye and the materials are pretty flat and have no visible texture.

Hey Peter,

I have tried different environments. In any case, if I turn the brightness way up, it helps. The issue isn't so much with it looking "interesting." The issue is that it turns out grainy and blurry. So far I think the thing that has helped the most is the depth of field and the blur settings in the scene settings.

 

While I'm here, another question in regard to this is about the ground plane. If I turn the ground plane on in the scene settings, the shadow shows up on the "ground," but the shadow doesn't render in the image. Is there a way that I can get the shadow to render in the image?

 

Thanks!

Without having access to a design I can't really help. I cannot say that I've encountered such problems, my cloud renders turn out very crisp.

Try to render without a ground plane and let us know if that makes a difference.
