Cansting shadow desappear with Instance static meshes ISM

Hi,

We are creating a world and we have some assets repeated. We are using Instance static meshes to get a better performance. But we have an issue, if we use this ISM we can’t control the shadow distance.

Here I created a sample scene to show you what is going on. The green objects are in a ISM and the red one no. We are not using nanite

Could someone help me?

Thanks

Julio

I don’t get how you’re making this happen :). I have ISM, HISM, static mesh etc in the scene, they all have almost infinite shadow distance

How did you construct the scene? What sort of distances are we talking about?

The way I created the ISM is placing the cilinders in the scene, then I selected all and merging it using
Actor->merge actors->batch.

When I refer to distance, In some videos I watched that we could decide when the shadows appear/desappear.

I hope I explained well

That’s what I did :slight_smile:

You can set the shadow distance in the details of the directional light, but I don’t know about the difference between types of meshes.
