Hi

I found HeightField Project node not works as expected on a transformed heightfield.


It works fine if I ues HeightFiled Transform instead of normal Transform node,But in some cases I must use the normal Transform node, for example UE4 plugin use transform node internally to rotate the input landscape into right axis.

submit a bug

and if you want to temporarily fix it
unlock it, dive inside and on perform_projection node change line 35 from this:
to this

I think transform SOPs are not intended for use with heightfields. Use the heightfield transform SOP instead.

while not intended it should work as it changes the domain of the heightfield volume, that's no reason to break the tools

but of course to transform the height values use Heightfield Transform, however Heightfield Transform contains transform SOP inside too so if you are using Positioning and your HF Orientation is not XZ it will break the projections too, even though that could be considered another bug as HF Transform shouldn't assume XZ orientation
