Display problem in Rhino6

Hi~

In my sample file, I import picture and input scale.
Because I want to change textures coordinate on the mesh which extract from object.

My first problem is I can’t see the result immediately. I need to select the object again or change viewprot to show result.

And second problem is when I run my program again, I select the same picture and set different scale, it doesn’t show result, even though I select object again. I need to change an new picture and then I can see the correct result.

But this program works fine in the Rhino5, it can see the result immediately.

So I get the render mesh from Brep const ON_Mesh* mesh = F->Mesh(ON::render_mesh); And I change the texture coordinats from m_T in the mesh. ON_2fPointArray Texs = mesh->m_T; for (int i = 0; i<mesh->m_T.Co…
