Nice presentation Magnus !!!! Wondering, wouldn’t the good old xyz function be better to stick hpaint stuff on a model ? (instead of the raycast method). Maybe there are flows with that method I don’t understand tho 😉

yup, probably very ugly ‘coding’ wise, but … it works :O) (still need to add the break/stop) condition … kinda hypnotic 🙂 (I should rename it “retarded postman” or something 🙂 )

totally, seems that openIO won’t area-sample pngs

well, multiple calls of colormap it is

totally works with the mandril

for posterity, this is how I solved it with multiple calls of colormap: “`c vector uvw = set(v@P.x+.5,v@P.z+.5,0.0); string texPath = chs(“tex_path”); vector colors[] = {}; for(int i=0;iv@Cd = avg(colors);“`

@squidbean yes and yes, and use .tx, works great for me. You can also use {“KARMA_XPU_OPTIX_SPARSE_TEXTURES” : “1”} to force it to sparse

re mipmapping, it picks correct mipmap level from tx. You can check with this map for example, if you don`t have one around already… dgruwier.gumroad.com/l/LJehG

It`s fun map to use, for example checking displacement, comparing engines etc, fun fun 🙂
