Production Light build issues

Quick facts:

  • Levels are being streamed (2 of them)
  • 1 LMV (Whole Terrain), 1 DIRECTIONAL LIGHT (MOVEBALE), 1 POST - UNBOUND
  • This crashes at the processing textures stage…
  • Getting no other critical error that I know of.
  • Machine (4.0ghz/32ram/4gb Vram)

Hi mdunham,

Can you post your crash logs? These can be found at \Unreal Project\PROJECTNAME\saved\logs. Additionally, can you post your dxdiag here for me to take a look? Thank you!

Hi mdunham,

We have not heard from you in quite some time. I am marking this thread as answered for tracking purposes. If you are still experiencing this error, please comment with the requested information. Thank you.

Hi , I have the same problem. I’m on Unreal Engine 4.6.1…I’m also uploading my Logs, so please take a look…thanks in advance…:slight_smile:

My issue was related to our world size being to too large and light to complex. This would work on the Mac for some reason but in bootcamp it crashed. This is no longer crashing as we have switched to streaming levels.

Hope that helps.

Hi mdunham,

I’m happy to hear you found a solution to your particular crash. BoisterousGaming, has this occurred on a blank project with no additional content or is it limited to one specific project?

Hi , I have the same problem. I’m on Unreal Engine 4.6.1…I’m also uploading my Logs, so please take a look…thanks in advance…:slight_smile:

no it never happened to me before in any blank project, but with a specific project, i have attached a screenshot of Scene Outliner of my project…Landscape size 8129x8129, PostProcessVolume and LightmassImportanceVolume are bigger than landscape size.

If you use streaming levels as mdunham mentioned do you get the same errors?

Hi
I’m not using streaming levels process, but now I’m going to use that method and let you know what happen…
