Thanks Jeremy and Akash. re-importing the .rmtl files fixes it here too.
It seems odd that the material doesn’t apply correctly when the file opens.
The color on the satin and the sandblast finish appear considerably darker in Rh8 than Rh7 (see above for contrast). In Rhino 7, these .rmtl files all show the same base tone with different textures. Any idea why in Rhino 8 the satin and sandblast both look orange?
Hi
I got the correct color for the sandblast when current render was set to rhino render.
when it was set to Bella, I got the dark shade like yours. [but both rendered with raytraced ]
Maybe try to play with this [you probably have other renders installed …?]
No idea why, But if you get the same results, then it’s a clue to the issue perhaps
I don’t have Bella, just Rhino Render and Legacy Rhino Render. I tried bouncing it back and forth between the two, but the Satin and Sandblast still look orange in Raytraced. They look normal in Rendered.
another guess… it might be a Window specific issue, since it renders correct on my Mac but @jeremy5 also got the dark color when he tested for you… Maybe time to tag a Dev.
Hi Mike - I think we had some of the channels reversed at some point - I’ll take a look at your materials and see if I can figure it out - might still be there in some cases.
@MikeM there are textures missing for the Satin material.
the renderer was updated to cyclesX, right? when blender updates cycles, then changes in how light, materials, etc are calculated do happen. so I think to some degree we can expect some differences in the visual outcome. may or may not be related to this specific case though.
when you have the current renderer set to rhino render, you will see these options for gamma & linear workflow:
these will be applied to any viewport by default, regardless which renderer is set as current. We don’t want this for bella viewports, so the plugin initially sets the bella viewport display options like this:
with this done, rhino is free to do what it likes to other viewports, and bella is able to display its output as intended, so check & see if this helps explain what you are seeing
OK, so the links to the texture maps aren’t unpacking properly when I open the .3dm file? But they do unpack normally when I import the .rmtl file? Aren’t these images embedded in the .rmtl file?
Ok, so it looks like I need to re-save the materials in Rhino 8 and make sure that I am embedding the support files.
I tried that on this .rmtl file, closed Rhino, and deleted all of the unpacked temporary files from: C:\Users\mmagee\AppData\Local\McNeel\Rhinoceros\8.0\UnpackedFiles
When I re-opened Rhino, the material loads without any error messages.
So I think that’s one mystery solved.
Next mystery, why is this material weirdly orange?
Poking…
Looks to me like Cycles orangizes yellow in bitmap textures.If I use a ‘Single color texture’ of about the same hue, it looks correct. A single color image looks too orange.
The Satin and Sandblast materials are still coming out orange, but the Brushed and Hammered are not. That tracks with what you’re saying. Both Satin and Sandblast have an image for the base color, while Brushed and Hammered have a solid base color.
