Hi Stezi, perhaps RasterExtentsCoercer - Replaces the geometry of input raster features with a polygon covering either the extents of a raster or the extent of data within a raster.

Otherwise use RasterInterpretationCoercer if you need alter the interpretation type of rasters, including all bands, and converts cell values.

Something like RasterExtractor follower by RasterReplacer like this GeometryCoercer to polygon

As the input is a mesh, unfortunately those raster transformers won't work.

There is NumericRasterizer but it generates the raster based on z-values. However, I want to create the raster from texture color values.

Here's a similar question from a couple of years ago

The solution was to first convert to a pointcloud

Great solution (PointCloudCombiner > ImageRasterizer)! :)
