Landscape freezes engine for a few seconds

Every time I modify my landscape it freezes for a few seconds after I release the left mouse button, and in the output log I get this message “LogTexture:Display: Building textures: Texture2D_923_BaseColor (BGRA8)”

I’m reporting it as a bug since I never had this in 4.7.6.

Hi ,

Can you post a copy of your dxdiag so I can take a look? Does this occur in a clean, blank project with no additional content or is it limited to one project?

I checked around and I found what the Texture2D_923_BaseColor is. Landscape > Manage > Selection Tool and click on a component, there is a tab called “Baked Textures” “GI Baked Base Color Texture” and there is the Texture2D_923_BaseColor refereed.

Since the tool-tip said it had something to do with the Distance Field GI I figured it might have something to do with “Generate Mesh Distance Field” I went to Project Settings > Rendering > Lighting where the field for that is and I noticed something new called “Generate Landscape Real-time GI Data”. I unchecked that and the editor no longer freezes for a few seconds. I don’t even remember turning that thing on.

Not sure if I should mark this as fixed or not.

Hey ,

Ok that makes sense. Distance Field GI is still extremely experimental right now. There are several known memory leaks and lots of optimization issues with the system as a whole so having it on at present is not recommended in the least. There is a forum thread that Wright started on the state of DFGI that can be useful to get the most recent updates:
