I have 2 questions What determines shadow culling? ie as I move away from the Virtual Height Field mesh dynamic cast shadows disappear. Shadowing from movable light sources is provided using object Distance Fields for each rigid mesh to compute efficient area shadowing from dynamic light sources. g. I will try to disable In this video I look at how we can fix the issue of objects disappearing from reflections as the camera moves further away. It’s not that it *never *works, because on some meshes the shadows keep on popping up and disappearing - leading me to think it has something to do with the distance calculation. MinScreenRadiusForCSMDepth which is not used anymore, r. In other words, your static shadows disappear at a certain distance from your meshes. Is there any way to do this and if so, can anyone send an example blueprint. I had a problem with my sun lights far shadows that actually got better by lowering the something distance from like 30000~ to 10000~, so increased values might not always be better.

By default, MegaLights uses ray tracing, and shadow quality depends on the quality of Ray Tracing Scene representation. Just as with regular geometry, the vertex-processing rate may be improved for shadow volumes by culling shadow geometry outside the view frustum. However, using the mesh in an Instanced Static Mesh or as Foliage breaks it shadows and reflections. Any help would be appreciated, thanks! Archived post. If you changed your meshes to movable, this means they need their light source to cast a dynamic shadow. It should be noted that I’m not particularly worried about performance. The vdb must be visible at any distance. Even really small light (light which affect really small portion of geometry) still exist behind the camera when i use freezerendering command.
