ForestEdgeMap bug with Forest Objet as geometry in Corona
« on: December 13, 2023, 12:47:10 PM »
Hello,

In Corona, ForestEdgeMap doesn't work when a "Forest Object" is taken in a second "Forest Object", I checked the display mode in meshes for the object in geometry but nothing helps. If you add an Edit Mesh on the Forest used as a geometry object, everything works again.

If you're looking at the ForestEdge Map and fixing this bug, it might be interesting to see how the Corona/vRay developers have created their ChaosScatterTrimmingMap to optimize the map within Forest. I get the impression that when you put the ForestEdgeMap on a very heavy "Forest Object", it's already scanning and calculating the opacity it's going to have to do, so the interface gets heavier/more sluggish. This should only be done when rendering, it's invisible in the viewport anyway.

Hi,

Although Forest objects can be nested, instancing is only applied to the "top-level". Any "inner objects" are converted to mesh. Depending on the render engine (and its release), the Render Mode for the used "nested objects" should be changed from Automatic to Meshes under the Display roll-out. That should help.

Best regards,
