Rendering Speed in SU 2016

Hi Al,

I have been using IRender for more than a year and we got it to work great on Sketchup 2015. But now on Sketchup 2016 the time to render is much longer (up to 4 times longer).

Do you know if there is a adjustment I must make for it to go faster or what should I do?

This should not be the case.

We will run a check here.

Can you render from both 2015 and 2016 on the same machine. If so, we would like to zip up the two batch folders, have you send them to us, and compare them to see what is different.

A small model would be best - just set it for enough passes so you can see the speed difference.

You can find the batch folder location from the Setup Wizard

You could try checking the rendering statistics as well - once in SU 2015 and again in SU 2016

Right click on the top of the rendering window to bring up statistics

The check for differences.

1. the number 64 in the name of the batch file.

2. The number of threads used for rendering.

3. The number of faces, lights, etc.

4. The rendering time and extract time

Hi Al

One thing I've just found is to do with the new default tray, it increases the size of the Y value when turned on therefore increasing render time.

Cheers Richcat

I did a test, reloading and older version of IRender nXt from last March, OC20, and rendering in SketchUp 2015 and then used the latest version of IRender nXt with SketchUp 2016 and got similar rendering times with both tests. I stopped the rendering during the15th pass.

Sketchup 2015: 13 minutes 27 seconds

SketchUp 2016: 13 minutes 59 seconds.

I also did a similar test with lights in the model, to see if something was different there, but the SketchUp 2016 results were actually faster in that test.

Here are some images of the statistics dialogs for the first test

Is this the Y-size of the rendering, or something else?

Hi Al

Yes its the Y value of th rendering on the render setup options page

Tool Tray off

Tool tray on

You can use the "Save Batch Folder" function to put all of the contents of the last batch rendering folder into a zip file that you can send us. Then we can render the exact same data as you are, and see what the settings are set to.

And you can use this link to send us large files:

Please also send us a note of explanation if you send us support files.

Hi Rich

Richcat, why did you send us a batch file?

I was posting that "how to send" information for anyone else who might have a problem, like the original user who sent us an email that rendering took 4 limes as long in SketchUp 2016. Are you having a problem like that?

Or are you just showing us that tray makes the rendering size larger?

ooops - I thought that was directed at me - do you want to start another thread.

I was just trying to show that the only difference I have noticed between Sk15 and Sk16 was yes it did seem a bit slower to me, but when I turned off the Default tray it went back to normal and the only thing I could see different was the Y resolution changing which I thought would have got smaller not larger.

I've just used one of the test models to render a corner of it and that render 49 passes in 11.4 mins and with the default tray off and 13.9 mins with it on.

If it was a more complex larger model would this be an even greater difference which could equate to roughly the 4 times the slowness indicated above or am I showing my age.

Hi Al,

I did what you asked me and this time and this is the results:

Sketchup 2016

\IRenderBatch64.exe

Max Threads: 8

Extraction Time: 16.0 seconds
Loading Time: 1.0 seconds
Render Time: 42.1 seconds
Passes: 20 (AR: 20)
Geometry:
Meshes: 1350
Faces: 97396
Materials: 22
Lights: 0

And for Sketchup 2015

IRenderBatch64.exe

Max Threads: 8

Extraction Time: 16.0 seconds
Loading Time: 1.0 seconds
Render Time: 37.1 seconds
Passes: 20 (AR: 20)

Geometry:
Meshes: 1350
Faces: 97396
Materials: 22
Lights: 0
Material Illuminance Lights: 0

Test 2

2015

Same threads and batch

Extraction Time: 51.0 seconds
Loading Time: 2.0 seconds
Render Time: 25.6 seconds
Passes: 20 (AR: 20)

Geometry:
Meshes: 8431
Faces: 106104
Materials: 45
Lights: 0
Material Illuminance Lights: 0
ArPlants: 0
RPCs: 0

2016

Extraction Time: 58.0 seconds
Loading Time: 2.0 seconds
Render Time: 25.7 seconds
Passes: 20 (AR: 20)

Geometry:
Meshes: 8431
Faces: 106104
Materials: 45
Lights: 0
Material Illuminance Lights: 0
ArPlants: 0
RPCs: 0

I see that this only a couple of seconds slower than in 2015 but the other modell I was rendering yesterday took more than one hour but I can not test this one in 2015 since I can not open it.
