Losing the texture mapping, from NURBS object

Hello everyone,

I need to convert my building (with its textures and everything) into meshes.
When I do it from “mesh” :arrow_right: “from NURBS object”, something weird happens to the textures. It doesn’t perceive the texture mapping that I created before, and fixing everything one by one is really difficult. It is Rhino5.

Do you have any suggestions?

Best regards,

Pinar

Hi Pinar - does ExtractRenderMesh do a better job?

Hi Pascal,

Unfortunately not.

You can see it from the photo, it is totally ruined… I have already spent so much time to apply the textures nicely to make it look realistic, now I need to re-do them again in Mesh form. This is really frustrating. Please if anyone has a suggestion, don’t hesitate to share it with me.

Hi Pinar - can you please post or send me a file with one or two objects correctly mapped with the materials, and please make sure to save with textures.

Hi Pascal,

Could you give me your email address? I got a warning that the file size is too big.

Dear Pascal,

I managed to upload the file here.

You can find it in the attachment.

Hi Pinar - what happens if you set all the textures to use WCS Box style? Use a sperate copy of each texture sized appropriately for each material that uses a texture that is scaled differently - like the Old Brick texture is used multiple times - then the conversion to mesh is correct, though, I am not sure yet why your setup does not work.

@aksupi - V5 this time…

Dear Pascal,

I use Rhino5 so I can’t open the file you sent me.

What do you recommend as a solution for Rhino 5? I have to use Rhino 5… I can’t upgrade it.

Thank you.

Hi Pinar - it looks like V5 does not do the right thing when a mesh is created, even from a WCS texture.

-Pascal

Hi Pascal. So you say there is no way that I can make it work with V5?

Well, I can say that it is not working for me so far… creating meshes in V7 seems to do the right thing with wcs textures, but not V5.
@aksupiExtractRenderMesh may get you the right texturing, if that mesh is OK for your needs.

Dear Pascal,

I have a couple of questions.

  1. If I create meshes in V7, would I still be able to use them for RhinoCity plug-in? (But this plug-in is only compatible with V5.)
  2. I have the trial version of Rhino 5 on my personal computer (90 days). Can I upgrade it to Version 7 and then bring it back to Rhino 5 after I create the meshes?

Best regards,

Pinar

Hi Pinar -

We don’t have the RhinoCity plug-in - this is something that you would need to test.

I don’t see any form of licensing recorded on your eMail address…
An evaluation version of Rhino 7 is available for download from our website.

Hi Wim,

Since it is Rhinoceros 5.0 Evaluation, I don’t have a license. It says “Your evaluation period expires in 78 days.” Perhaps that’s the reason why you can’t see any record on my e-mail address.
We have the licensed version on the computers in the office, but since I am working remotely, I installed the evaluation version on my personal computer.

If you have any idea about how to protect the texture mapping when converting it into meshes in Version 5, I would be glad if you could kindly inform me.

Thank you all for your help.

Best regards,

Pinar

Dear Pascal,

I installed Rhino 7 now. I can finally work with it, but choosing WCS/OCS (box style) doesn’t help me a lot since I have to create the copies of the materials one by one for the each part the surfaces that I applied different texture mapping.

Do you have any other suggestion?

Best,

Pinar

Did you try to export Rhino file to obj and than import it?
Or try unwrap

Hi Pinar - I do not have a better suggestion. I think I understand now that the process is not so much the problem as the fact that you now need to re-do everything, because you’d mapped them differently previously, is that correct?

-Pascal

Hi Pascal,

Yes exactly, but somehow when I tried again with ExtractRenderMesh it worked! Thank you so much!

I have one more question: Is it possible inside Rhino 7 to save for previous versions of Rhino? In some other software it is possible to save the files to be compatible with previous versions.

Best,

Pinar

Hi Pinar -

Yes, if you use Export or SaveAs, you can pick from a list of formats, including previous Rhino versions:
