Hi guys  I`m working in 3dSMax for over a 10 years now and recently started learning Houdini. And at the first day of learning it the fact that you cannot apply the scale attribute to a mesh object but you can apply it to a point made me not only confused but pretty mad   I remembered some friends say "when you learn it more it will start to look pretty logical and intuitive". Well, it means that I haven`t learned it enough yet because wherever I look it just pure illogical hell to me. I hope someone will explain at least any of these things to me, I will appreciate that : 1)  Why points have wrong coordinates on some geometry objects like spheres and tors and ok on others like grids and boxes  ? When I create a sphere from scratch on a new scene and turn on point visibility and numeration I see the points 0 and 1 appear to be the highest and lowest point of the sphere and in a viewport they are placed in the 0 coordinate of x and z axis (of course). But when I open geometry spreadsheet their coordinates are -2 , 0.5 , -5 and 3.6 , -0.5 ,  9.7 respectively. When I do same with grid or box everything is ok. What`s going on ? 2) Why normal N attribute is 3 float by default and not vector ? 3) Why when I declare vector parameter with a channel by typing "vector freq = ch ("freq");" and press "Create spare param" button it creates a non vector but single value float parameter ? 4) See attachment . Why when I type @P.y=sin(@P.x); in an attribute wrangler attached to a horizontal line it gives me spiral (like it should)  but when I do same in point node's VEXpression field it gives me some weird line in viewport (and its P.x coordinates are changed for some reason as I see in the spreadsheet) and I need to type @P.x=self;@P.y=sin(@P.x);@P.z=cos(@P.x); in order for spiral to appear forcing P.x to stay same (not to be changed change by Point node like before). Meaning that point node affects P.x component even when I`m not touching it while wrangler only changes what you tell him to. It was tested on different versions of Houdini. Thank you

Or you use VEX to apply UV coordinates onto the roof: // VERTEX WRANGLE float s = ch('uv_scale'); vector up = {0,1,0}; vector nml = normalize(prim_normal(0, i@primnum, 0.0, 0.0)); vector tang = normalize(up - dot(nml, up) * nml); vector bitang = normalize(cross(-nml, tang)); vector pos_rel = v@P - prim(0, 'P', i@primnum); float u = dot(pos_rel, bitang); float v = dot(pos_rel, tang); v@uv = set(u, v, 0.0) * s; Align each polygon to the bottom left corner of the UV space: // VERTEX WRANGLE string geo = geounwrap(0, 'uv'); vector size = getbbox_min(geo, itoa(i@primnum)); v@uv -= size; roof.hip
