It’s great D5 shows Rhino’s native curve piping so that less geometries are made in the model. However, the material is a bit off.
All curve piping is applied with the same material, and D5 shows it as the same material. However, when that material is changed to illuminated, only one curve pipe that’s selected in D5 gets illuminated. All other curve pipes are not illuminated even though D5 shows it as same material. You have to select each pipe and turn on illumination.
Is this a bug?
Hi @bcsadmin
Did these pipes have the same material assignment in Rhino before syncing to D5? Also, could you please send a short screen recording showing the problem, and your Rhino plugin and D5 versions. Thanks!
Does this not happen on your end?
Hi @bcsadmin
Could you send a short screen recording showing the issue? It’ll help us see if something unusual is going on.
If the same material was already assigned to those pipes in your Rhino model, then after syncing to D5, any change you make to that material (like turning on illumination) should update across all pipes at the same time.
but if the materials were different in Rhino and you only assigned the same material inside D5 afterward, D5 may still treat them as independent material instances. In that case, the changes won’t sync across all pipes, and each one might need to be edited individually. Thank you.
all materials were assigned in Rhino before opening D5 (i mentioned d5 read material correctly as assigned in Rhino). Even though the material shows up same in d5 for all curve pipes, I had to assign illumination one by one.
I will try to make a video.
Hi @bcsadmin
Yes please, that would be very much appreciated — a short video will help us understand the issue better.
Also, could you privately send me your log files using the support tool. Thank you 
messaged you a wetransfer link with screen recording and log files.
In the video, you can see that curve pipes are all assigned with ‘neon red’ material in Rhino, but in D5 those have to turn on individually for emissive even though it shows up with the correct material name, neon red. All of them have the correct base color, but emissive won’t work as one material. I can even assign different emissive color on each curve pipe.
I sent you another video with Emissive not working as expected. I did some testing, and this bug happens when the object has either Rhino’s curve piping or edge softening.
hi @bcsadmin
thanks for sending the additional video and details. I’ve received your files, and we’ll be using them for testing on our side. I’ll keep you updated as soon as we have more information. Thanks again for your patience
Hi @bcsadmin
Just an update regarding your case — our team found that the plugin isn’t handling Rhino’s curve pipe mesh info correctly, which is why D5 detects them as separate materials even if they share the same name. This is a known issue for now. We’ll be debugging it and aim to support this feature in the future version. Thanks you for your understanding.
Please note that the 2nd video shows that Edge Softening causes the same issue as Curve Piping.
When you fix this, could you please add support on Rhino’s Decal? It’s so much easier to use decal in Rhino than trying to add it in D5. Rhino’s curve piping, edge softening, and displacement shows up in D5 but not decal.
Hi @bcsadmin
This request has already been submitted. Rhino Decal Support?
We’re monitoring this for Rhino decal support, as well as improvements for curve piping, edge softening, and displacement. Thanks!
A new bug found with Rhino curve pipe is that, even curve pipe is moved in Rhino, D5 won’t move it even after resync.
If I turn off the curve pipe, it won’t show the curve of course. However, once it’s turned back on, D5 shows the curve pipe in previous spot.
