UV not calculated for boolean operations

[Yatsomi]

hi dude, i think its usefull to calculate uv after boolean ops, in many cases we have a mesh with texture on it to cut. tnx

Hi. I have looked at this, its not really very simple when dealing with intersections and joins. The objects need to become multiple objects (per material join) which complicates things in the code.

You are welcome to have a look and see if you can create a patch for it.

i looking for a tool to do csg on Quad in unity in entire internet, but its just ur tool, and im not that pro to write a csg for myself :). i just use subtract operation on Quads, its all i want, subtract a quad with 1 material, is it still so hard to achieve this? tnx dave

omg such a noob i'm! its just a quad. uv generated by vector2(1 - vertice.x , vertice.y) :)

Hi, Not quite right, it depends on a few things (the uv needs to be scale to the object size) - 1.0 - (vert.x / objwidth) and vert.y / obj.height . Its not exactly this, if the texture mapping has repeats and previous mapping offsets. You can do the above in texture space, and there should be shaders/materials available that you should be about to use to do this anyway.

Heres a solution that would work for your use case: https://stackoverflow.com/questions/41362625/how-to-calculate-uvs-of-a-flat-polygon-mesh

I cant really apply this. I may make a cubemap available but its not very useful in three dimensions. Hope the above helps.

y ur right, tnx so much dave, that was exacly what i looking for! wish u best bro :)
