Rayscaper only considers the material assigned to the front face and ignores the material on the back face. Incorrectly oriented faces will result in shading issues because Rayscaper uses the normal of the face to determine what's the inside/outside of an object for lighting calculations. This is no different from other rendering software.

I then attempted to reverse the faces but Sketchup froze, Rayscaper was rendering even while minimised. I checked several times to make sure I got the same thing.

What do you mean by minimized @Mike-Amos ? When the Rayscaper window is still open, even when minimized on the taskbar, it will continue rendering. You can pause the render, but if you update the geometry (e.g., when flipping a face), the geometry update needs to propagate to Rayscaper, which might be costly. You need to close the window to avoid any overhead caused by Rayscaper.

[Mike Amos]

OK, when the render is PAUSED.

I minimise the Rayscaper window to attend to any changes I may wish to make.

For reasons unknown to me, the render then restarts. To reiterate, I have PAUSED the render prior to minimising the render window.

I will have a look a this then @Mike-Amos - But paused mean paused, it should not restart and unpause itself.

Over the last year or so, I gave up thinking x 'should not happen'. Far too many issues have come to light. Different plugins causing freezes at different times and win doze updates doing the same, onedrive being installed on my OS drive and stealing my files without an invitation that if I want to keep using them I have to pay............

@Rich-O-Brien

Thanks, Rich. APpreciated. Better.

[Mike Amos]

Well, not noticing the walls banish was a faux pas alright. Opacity to 4% somehow.

The floor too.

Reassigned matt finish after deleting mats and reastarting Sketchup seems to be the charm.

Some lighting for the workspace.

[Mike Amos]

OK, I cannot even select a component and an axis, then move the component to ANY degree of accuracy. Bam bleeping boozled.

[Mike Amos]

OK, seems a buggered component. I know.

I got this fromm chillblast who think the onbvoard graphics have to be used with sketchup and ignore the fact that this item cannot be seen.

Hi Mike,

Thank you for your patience, unfortunately I have been out of the office.

In regards to what the person that had a look at the computer advised on, There is no flaw with NVIDIA graphics and Windows 24H2.

I believe you have 2 systems in total, one from 2015 and a 2022 one, and as I am aware Both systems have integrated on board graphics, which you should use with Sketchup.

Without testing the system, which we can look to arrange, we cannot diagnose the faults you advise you have. We can certainly remote onto your system as well if that helps, without testing it we can only assume it's issues with the software. Your newer system came back in May/June last year and was testing and found no faults.

Many thanks

Dave

OK, motre data, Windows big 2025 update has had some issues which they "Hope to resolve soon". I asked when "Soon" is but no clue that end. On top of that, nvidia updates are problematic too. Apprently the nvidia updates are conflicting with windows updates, left and right hand thing I suppose.

nvidia tell me they are working on a 'patch' for release in the next few weeks but no guarantee.

Seems that A lot of the issues are conflict related, lags, freezing etc.

The very strong directional light of the background image isn't continuing into the kitchen space.

Did you try add a Sun light pointing in the same genral direction. You could slow dial up the power so it places nice with the internal light setup you have.

Sometime HDRs + Directional can be used together to hack nicer shadows. But re-rendering is needed, which is a painful pill to swallow.

Is this Rayscaper or Twilight?

[Mike Amos]

Ta Rich, this is Rayscaper. Soft lighting is something I cannot find, nor understand the 'fog' I see here. Not talking about dof.

Twilight has a decent ability to create a 'plane' and assign hdri to for direction of lighting.

This hdri is a favoiurite of mine with the sun rays etc.

[Mike Amos]

I have added a directional (Rayscaper) light and set to sunlight which IIRC is 6800k. Aimed into the centre of the view.

[Mike Amos]

Trying a Hotrod which I have rendered before in Twilight V2. Initially opening Rayscaper led to failed renders. Just va simple report, 'Failed'.

Being a Hotrod, there will be flames. The PNG is on a seperate 'face copied from the model and painted as a component. Twilight see's the transparency fine but Rayscaper does not, when it does render.

[Rich O Brien]

Spicy. Interesting that Rayscaper fails. Is this model very heavy in terms of file size?

[Mike Amos]

@Rich-O-Brien

Not that big, nor the texture.
