The object disappears in a distance…So where can i find the"Max view distance ratio"options or sth else,thanks

Hi Min++,

What kind of distance are we talking here? is this a short distance that the mesh is disappearing or far off?

You can set the cull distance for a specific instance of a mesh in your scene via the details panel or open the mesh in the mesh editor/viewer and set it there for all instances of this particular mesh.

There is also the bounds scale that will occlude a mesh if it’s not mostly visible. This can be adjusted by using the bounds scale but using this can obviously lead to performance and shadow quality issues if scaled too big.

Thanks!

sorry ,can you give me a image captureed to show the specific position of the cull distance and the options in the mesh editor.I cannot find them.Thank you!

When you place the static mesh into your level, in the details panel you can adjust the settings from the Rendering → LOD section.

sorry, i didn’t make any LOD model,just the primitive model.It is a tree, when you watch it far away,the leaves dsappear,only trunk left.How can I fix this problem,thx!

You don’t have to have multiple LODs setup. Your mesh with no other LODs is still considered a LOD. It’s the base LOD or LOD0, however you’d like to think about it.

The tree you created, was it made with SpeedTree or a custom asset?

yep.it is just a simple polymesh created in maya and the leaves part is of course made of planes applied with transparent textrures

There are two things I can think of off-hand that may help.

There may be something with your material setup. Can you try setting the material to no be translucent or masked for a test?
If that doesn’t help narrow down can you try increasing the bounds of your static mesh via the detail panel to 2 or 3 for the selected mesh.

If neither of these work would you be willing to share the asset and I can take a look and see if there is anything that stands out. If you’re willing to you share you can post a link here or send a link via a private message to me in the forums.

Thanks!

Hi, I was having the exact same problem. I had a tree that I modeled and textured in maya. When I brought it into UE4 and set up the material it looked fine close up but as soon as you went away maybe 1500 units the leaves began to thin out and nearly disappear.
I did however, find a solution. I was using a masked - 2 sided foliage material. If you’re using this you need to lower the Opacity Mask Clip Value. Don’t go to far changing this value though as it will result in a far too dense material. I set mine to about 0.22. I hope this helps.

I would like to nominate an upvote to Noah_Chu! Seriously… nice solution… I will be looking into other solutions, but this combined with a few custom LOD’s will do the trick for now! Obviously if we all had money we could just get Speed Tree… but I thank you Sir!

In my case I realised it wasn’t a culling issue but an emissive problem. If you crank it up it will return. The problem I had was scaling a sphere for the skybox but it could be a completely different situation you’re dealing with.
