It’d be great to have extended Static Mesh rendering options inside the Foliage brush settings. More specifically:
-
Adding Forced LOD settings to the Foliage brush: This enables developers to be able to paint, say, background trees at a lower LOD. (Or even paint a billboard strip leveraging this setting).
-
Adding ‘Render Custom Depth’ as an option for Foliage brush: This allows us using post-process effects (like edge shader) to be able to turn Edge highlights off of sprites when painting with them in Foliage brush.
-
For Speedtree, being able to tweak LOD/screenspace distances per-instance/per-foliage layer: this allows us to be more aggressive with trees we’re painting near background/mid-ground elements while still taking advantage of Foliage’s clustering bad assery.
-
The option to use either Screen-space OR distance-based LOD distancing. I find screenspace LOD settings to be really hard to fine-tune compared to unit distance.
