Hello everyone, I have developed a plugin in Rhino7 using RhinoCommon in C# and currently working on creating a plugin version for Rhino8. One of the functionalities in this plugin involves assigning and modifying texture mapping. While the functionality works smoothly in Rhino7, I’ve encountered t…

@andy - can you have a look at this?

Hello @陳志鵬 Sorry, it took this long to get to this. I’m looking into it now.

I’m running the code I received by email on a 500k poly mesh. These timings are made with Debug builds: Rhino 7: New Object Set the Same TextureMapping Back. Time:1 ms New Object Set rebuild TextureMapping Time:10872 ms New Object Set rebuild TextureMapping AGAIN. Time:6 ms Rhino 8: New Objec…

The time is spent computing texture coordinates for the object mesh (for mesh objects there aren’t separate render meshes as there are for nurbs objects). This involves looking at the mapping mesh and the object mesh and figuring out how they would best map to one another. This computation sometimes…

[image] 陳志鵬: Additionally, I’ve noticed that our plugin experiences slower performance under .NET 7.0 or .NET 4.8, but it performs normally in Rhino7. Hey @curtisw , who would be the right person to assist with this?

Hi Jussi, I have uploaded our file, thank you!

Thank you, I have received the model. I will inspect it next week :slight_smile:

Hi Jussi, Could you please provide an update on the problem? If there are any additional documents required, please let me know. Thank you!

I could not see a big difference in times between Rhino 7 and Rhino 8 with your model. But I see different behavior in which calls take the time. Some plug-ins modify texture mappings and that could be the reason why your Rhino 8 behaves different to mine. You can run _SystemInfo command and send th…

Thanks for your replying! I have uploaded our system information files to ［ Rhino - Upload to Support ］ If there is any way to resolve or circumvent this problem, please let us know. Thank you!
