Can't set Max Draw Distance in UE4.20 and 4.21

Development Rendering

Sample project ZIP: Dropbox - MaxDistanceTest2.zip - Simplify your life

UE4.20 started to bug with ‘Desired Max Draw Distance’ and ‘Current Max Draw Distance’. The later one property is always grayed out but it is the one which actually affects rendering.
Changing ‘Desired Max Draw Distance’ manually does not change ‘Current Max Draw Distance’ all the time.

In the test project provided, here are the cases when it works:

  1. For object ‘Floor2’, you can see that ‘Desired Max Draw Distance’ is set to 10000 but ‘Current Max Draw Distance’ remained 100 from previous edits.
  2. You can’t change it to, let’s say, 5000 immediately: first, you should change it to 0, then to 5000. Doing so will make your changes take effect.

That’s quite stupid workaround - you always have to type ‘0’ first, then type new value.

Case when I can’t find workaround - Instanced Static Meshes component (probably, any component) inside blueprint.
In map provided:

  1. There is a ‘NewBlueprint’ object with two ISM components, which have a few instances added.
  2. You can’t change their ‘Desired Max Draw Distance’ in any reasonable way - it changes only very first time, then it won’t change in 99% of attempts.
  3. When it does change, and this is actually crazy, is when you drag ‘Desired Max Draw Distance’ by mouse. Even in this case it is very buggy and does not follow your changes precisely.

I hate reviving old threads, but unfortunately it has been happening to me too.

Same here, and it is very strange and unproductive when dealing with lots of actors.

I also have a problem with ‘Desired Max Draw Distance’.
When I changed this for Landscape, I don’t see it in game. But when I returned to 0, it continue to be hided.

In a blueprint, I made it into the consturction script and it worked

[Solved] I know post is old but if any-one have problem they can find solution so just posting it here.
Hi, I’ve been faceing this issue recently, It works in game but not in editor and all.
Then in game i see that if i set view distance low every object is culled away. Then i came to this video WTF Is? View Distance Quality in Unreal Engine 4 ( UE4 ) - YouTube and everything became clear.

If I set engine scalability to cinematic then it won’t work. It is co-related to view distance scalability. Watch video you’ll understand it. I am not very good at explaining.
