Which is close to what we want. (And what we use at the moment)
Problem:
But I can not recreate this in an existing Rhino document. What setting causes the difference? We would like to be able to do this to other documents without having to import them, due to layouts made etc etc.
Ideally we would be able to tweak the shadow intensity.
Please see if you can manage to Reset to Default and then get this result.
Hi Jorgen - I’ll see if I can figure it out… @Holo - there is of course a difference, potentially, between Open and Import - here you are Opening in all cases, is that correct?
Here, if I Open the stl, skylight it not on - if I turn on skylight it looks like this in Rendered mode-
Which looks a bit better to me than your low contrast shot.
If I Import into the millimeters template, it looks completely washed out. If I turn skyling off, and back on again it looks like what I think is correct…
Thanks for looking. If you open the stl and then open the envrionment tab and look at the background of the environment while you hit “Reset to Default” you will see that the lighting changes there too.
So what controls this extra light is what I wonder.
Hi Jorgen - if I Open the STL, the skylight is off - if I turn that on, it looks good… but Import does not - I can make every setting that I can find the same in each and it still looks different - I’ll need to ask a bigger brain to see what is going on here.
@Holo it is still a mystery why the two ways of opening/importing behave differently but one thing that Jeff pointed out to me is testSSAOOptions > Intensity > 5 or so.
This will not stick to the file - but gets the higher contrast look when you need it. Hopefully some better idea will come from the developer when I add this to the bug tracker.
@Holo more on this - it seems like on Open the shading is only showing the SSAO shadow map without the usual shading of the objects. I think. So the good version for your test case is likely a bug of some kind and you should use the testSSAOOptions to control contrast. Until someone corrects me but I think that is the upshot. Jeff’s going to look at it more closely.
RH-81425 Display: Shading differs between Open and Import
That is exactly it!
It is the Dithering and Color Adjustment that does it.
The default in a default Rhino document is 2.2 but in an opened STL file it is 1!
This is perfect and now @Pascal and @kyle just needs to remember this so I can ask them again in the future, because I will probably forget it again since I am in the middle of coding right now
Hi all and thanks for all help.
Here you can see a low res version of the result of the illustration. This will be shown in a conference this week and the customer is very happy. This wall is the norther wall of Urnes Stave Church (Stave is the term for this construction) and was raised in 1130, it is carved in wood by late vikings and tar coated to withstand hundreds of years of sun and rain exposure. It is difficult to document by photo due to the darkness of the wall, but with 3D scanning and the use of Rhino’s display mode and gamma adjustment it pops out in a fantastic way.
PS! Here is a super simple script to set the gamma value and turn on the skylight for opened stl files etc for those who might find this in a search in the future.
import scriptcontext as sc
sc.doc.RenderSettings.LinearWorkflow.PostProcessGamma = 1.25
sc.doc.Lights.Skylight.Enabled = True
