What is a Lightmass importance volume?

The Lightmass Importance Volume controls the area that Lightmass emits photons in, allowing you to concentrate it only on the area that needs detailed indirect lighting. Areas outside the importance volume get only one bounce of indirect lighting at a lower quality.

What is blocking volume?

Block volume: A detachable block storage device that allows you to dynamically expand the storage capacity of an instance. Boot volume: A detachable boot volume device that contains the image used to boot a Compute instance. See Boot Volumes for more information.

How do you reduce the resolution of a Lightmap?

You can set the Lightmap Resolution of your mesh in the Static Mesh Editor under the Static Mesh Settings. The default in 64, which can be low for a medium or large sized mesh.

What is Lightmass portal?

Lightmass Portals are most useful when a scene is lit using a Skylight, HDR image or a Static Mesh that is set to Use Emissive for Static Lighting checked. Click for full image. Lightmass Portals are placed and in the level and scaled to fit any open areas that are important to the final lighting.

What are three key characteristics of block storage volumes?

They can be detached from one compute instance and attached to another in a different Availability Domain. They can be backed up to the Object Storage Service. They can be cloned. They can be suspended while not in use to avoid paying for utilization.

What is a blocking volume ue4?

Camera Blocking Volume Camera Blocking Volumes have pre-configured collision settings that block cameras and ignore everything else. They are intended to define invisible barriers that keep the camera out of unwanted locations.

What will happen if you increase the resolution of the Lightmap on a mesh?

Lightmap resolution for static meshes and bsp defines the quality and how sharp or blurry your cast shadows are across objects. Optimizing for lightmap resolution will help you keep the texture memory down and make your shadows look good on your meshes.

What is UV Lightmap?

This UV is called a Lightmap UV, which is similar to a texture UV in that it consists of laid-out UV charts (or UV islands) that are unique to each static mesh except this particular UV is used to store baked lighting and shadow information.

What is Lightmass in unreal?

Lightmass creates lightmaps with complex light interactions like area shadowing and diffuse interreflection. It is used to precompute portions of the lighting contribution of lights with stationary and static mobility.

What is a Lightmass portal in Unreal engine?

Lightmass Portals | Unreal Engine Documentation. The world’s most advanced real-time 3D creation tool for photoreal visuals and immersive experiences.

What is Lightmass importance volume and how to use it?

The Lightmass Importance Volume controls the area that Lightmass emits photons in, allowing you to concentrate it only on the area that needs detailed indirect lighting. Areas outside the importance volume get only one bounce of indirect lighting at a lower quality. You can add a Lightmass Importance Volume to a level by dragging

How does Lightmass affect lighting build times?

Lightmass emits photons based on the size of the level, so those background meshes will greatly increase the number of photons that need to be emitted, and lighting build times will increase.

How do I convert a brush to a Lightmass importance volume?

You can also convert a Brush into a Lightmass Importance Volume by clicking the Convert Actordrop down box inside the Detailspanel under Actor. After clicking the drop down box, a menu will appear where you can select the type of Actor to replace the Brush with.
