Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Spawning actor in levelblueprint; culling issues

Hi there,

Basicly I need help. Maybe it is a bug, maybe I'm doing something horrible wrong, can't really tell.

My goal is to let the levelblueprint spawn actors at level startup. And let those actors be culled at a certain distance. When I place my actors manually they get culled, when I spawn them they don't.

For the purpose of this repport I tried to recreate this phenomenon. I opened a brand new project ( engine 4.5.0 - extreme settings) with a new map, made a BP (BP_RandomObjects) which holds nothing more then a static mesh cube (S_Block) (which was created from a cube bsp) and has a very basic white material.

I place one actor manually in the level and one I spawn with the use of the following code:

Next I constructed a cull distance volume and gave it the following parameters: alt text

I build the project and run it in a standalone environment.

The result is that:

1) I get a warning message in screen ("lightning needs to be rebuild") ( even when i just buid it 1 sec ago)

2) when i''m closeby i see both objects (this is what I want)

3) but when i move away only one dissapears

4) additionally (but not the main problem here): The shadow of the object that i manually dragged and dropped into the level is horribly wrong

I don't understand it and hope my issue can be fixed!

Thank you in advance ;)

First off, Thank you for the detailed setup and clearly representing how to reproduce. Setups like this are great at being able to reproduce and get this submitted!

I was able to clearly see the issue happening with the Blueprint in the cull distance volume. I've submitted a bug report for this (UE - 5467). Once a fix is in I will test and verify so that I can update this post accordingly.

In the mean time as a work around you can manually set the cull distance for objects by using the Min and Max cull distance. Using this doesn't require using a cull distance volume.

Thank you for your detailed report!

Actually, this "bug" was closed a long while back. Cull Distance Volumes are only use static objects in the scene and do not work with spawned dynamic/movable objects. So this isn't a bug with Culling here.

If you need to have your actor culled you can set the Min/Max Draw Distance for the object in your Blueprint so that it is only visible when you are within those distances.

Apologies that I didn't update this post here.
