Add UV Map at runtime?
« on: August 06, 2019, 11:37:28 PM »
Is it possible to add a UV map during runtime, like a basic box map or planar map?

In my situation a user imports an .fbx, and applies materials to each part. Would be great to add a base UV map when the imported file lacks one.

Hi,

 It's possible, but not without heavy, heavy, very heavy coding :)


Bye,

I wonder if it is possible and easier to do it, by using ProBuilder 4s runtime API. I dont think there is much documentation there, but it should be able to create UVs. (Of course, this still require some coding, but potentially a lot less).

Edit: In this example they take a normal obj and probuilderize it. Make an adjustment and then rebuild it. On the rebuild process, it should regenerate the Uvs.
