Rhino 8 WIP status

Ok, I’ve updated the first post at Rhino 8 WIP Available Now! with the current complete list. I’ll try to continue to do so as we release each WIP.


Can I ask… Rhino 7 was just released, and Rhino releases are often years and years apart… why are there already seemingly bugfixes being moved to Rhino 8 instead of 7 (I see at least 1 bugfix that was reported for 7)?

I ask because I ended up awkwardly jumping between 7 WIP and 6 for a project, due to some fixes being in one but not the other, and that wasn’t a very good situation. I know I’m not alone in this, as I’ve seen people complain in several places on this forum that fixes are only done in WIP when they need them in production.

(I totally get it when a fix relies on a new feature, though.)

Generally ‘bugfixes’ that require some major rework of core code - possibly breaking other existing functionality and plug-in compatibility - are moved to the WIP so as to insure stability of the release version.

This is also based on the fact that since V6, the WIPs have been available in parallel to the release version - so there is no waiting really - you can have fixes and new features as soon as they are implemented instead of having to wait for the next release.

Guess I had bad luck with my fixes, but I mentioned production, because I remember pestering the developers whether I should use the WIP in production, and (quite naturally) the official word is no. :slight_smile:

Yes, the official word is always no until the WIP hits the Beta stage. However, nothing should prevent you from using the WIP for the things you need that are fixed and the release version for the rest - keeping your files in the release version format.

Remember when FlowAlongSrf and Squish and all the other tools using that tech first came out? And people were using the WIP in production even though it wasn’t simply likely to crash but might actually damage your files when it did? Good times. :slight_smile:

are we ever going to get good shadows?

In what? “Good” how?

It’s sunny outside here. Excellent shadows!

skp. simple fast clean shadows:

RH7 default:

after changing settings:

the shadow is not crisp (though you can fiddle with settings to improve this slightly you shouldn’t have to), and the light source is not fixed relative to the model. it makes it hard to judge what you’re doing. the dark area is pitch black for some reason… like it’s painted with vantablack. rhino could get sued by anish kapoor for this.


If you want to have raytraced shadows instead of a shadow map, check out this thread:

i don’t want this in a raytraced viewport. that’s going to kill my gpu. this should be level of shadows in the “shaded” view… the GPU in wireframe view already idles at +10 to 15 degrees F with Rhino open in a blank model.

I think you misunderstood: said settings are less taxing for your gpu.
I concur with your “vantablack” comment though.
I think this can be solved by custom lighting too, but it should look better on default.

@rhinouser11, are you talking about these kind of shadows? If yes, they can be set in the properties panel:

Cheers, Rudi


this looks very good but problem is performance, this is rendered view. what @rhinouser11 says there should be sketchuplike simple shadowed view possible

I want to ask Mc Neel if we are soon going to see version 8 plan of which features (or more generally) are going to be implemented and what is not to be expected. I guess right now you are in the process of assement. Thanks :slight_smile:

the shadow is offset from the object and it’s blurry. that is not clean at all.

In a display style under ‘other settings’ you can add cycles to the display pipeline, which will overlay the viewport rendering style with a production rendering, so you get real raytraced shadows.
Instead of this somewhat sucky shadow map…

this is what i get with the settings shown above from Rudi

the shadow is offset from the object.
the shadow fades out
the viewport is crawling with this simple scene. this can’t be used for actual work. I have an old gpu because of the current ridiculousness, but I should be able to work with a box and a plane without issues, no?
if i use “default lighting” the shadow moves around the scene, so I can’t judge what is going on.

Yes, I use a similar Rudi setup:
