Goal: use world position to texture map larger structures that does not have UVW created manually
1. Object coordinates out from the "Texture Coordinate" node seems to be world coord instead of object coords. Compared to Cycles and EEVEE at least
2. Textures sampling only seem to use flat sampling
3. vector converter node to map from (e.g) object coords to world coords is missing.
This is still missing as of the latest release. Additionally the "RPR Procedural" node doesnt solve this need. Please see massive post with screens below.
