Losing the texture mapping, from NURBS object

Rhino
, , ,
1

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.

Best,

Pinar

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.

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.

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.
@aksupi – ExtractRenderMesh 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

17

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?

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:
