Light build Error

Hello,

I wanted to build lights, but every time there is an error:

What can I do. I don’t know, what this is and how to fix. Has somebody an idea?

Thanks. Jojii

That was quick, thanks and just a Second

no, that does not work too…

Same problem. It chrashs after 10 seconds…

This part does not exists…in the error description.

is there an automatic way to find that, or do I have to make it manually?

ca. after 10 seconds… on 0% from building…

Hello

Change the foliages to movable, be sure your LightSource (Sun) is set to stationary and build again.

Let us know.

Good luck!

hmm, seems that you have a material or mesh that is giving this error, you need to find witch one is doing that and perhaps delet it to see if the error stops

did it started just now or it is happing for a long time?

I mean your project, it always happend this?

Castshadows were disabled before in rendering settings, but I wanted to have some Shadows and more performance per Lightmap… So I decided to turn Castshadows on and as I wanted to build them this error came. I tried this ca. 4 times but it never worked…

For clarification, Lightmaps are supported with Instanced Static meshes (specifically foliage) which you can find documented in the link below.

Foliage Instanced Meshes

Keep your Directional Light actor set to Stationary, and also be sure you are not exceeding the resolution limit per cluster of foliage.

The error message you are receiving could be due running out of memory on your computer, which causes Swarm Agent to fail. Would you mind providing me with your systems ‘dxdiag’ so I can take a look at your computers specifications?

Thank you,

sorry, I edited my comment because I gave a wrong information. Thanks!

No worries. It is all a learning process and the engine is constantly being changed and updated!
