[PathTracer] InitializeLightmapData job with hash: 120fb6e5e3ae5bc68ee62d5005962700 failed with exit

Hi guys,

I'm new to light map baking, so please bear with me.

I tried to bake my level today, it's been running over 7 hours. The original estimation Unity told me, was 3 hours.

I came back a few hours later, to see I had 18 minutes left. Which I was pretty happy to see. But then I noticed whenever it reached 12 -13 minutes, the baking time would reset back to 19 minutes.

I don't think my bake is going to finish. I'm baking a 2d platformer, that's made with 3d objects. So I can't really say it's an "outdoors" environment. (I read in another thread outdoor scenes would be better off using Enlighten)

I've attached some screenshots about settings and the error. I used Mesh Baker (asset store), to combine as many objects as possible into "chunks" of assets. For example: a house and its surrounding trees would be a chunk. I made those "chunks" lightmap static only. There's around 20 of these "chunks" and I have smaller unique detail assets like street signs etc, as their own individual game objects.

I have about 30 lights. (Is that too much? They're set to Mixed)

Should I be making my "platform colliders" static as well? They have a mesh renderer on them so I can see them in editor, but are not rendered by any cameras at runtime. If I made them static, would those be considered in the lightmap baking process?

Any help would be much appreciated!

Thank you

 

I had similar problem recently. I don't know how I fixed it but turning off some objects then rebaking lightmaps helped me. So try to find that meshes that are not correctly baking or causing errors and rebake, also i noticed that if you have empty gameobjects that are static also causes this error.

EDIT:
Error might also occur because of windows paging file size, try to increase it.

 

Sorry for the late reply.

I ended up going with Enlighten and was able to finish in under 30 minutes. I also redid my mesh baking into smaller chunks. It seemed to help.

 

Just to add to this thread for anyone encountering this error:
I disabled "Prioritize View" and "Multiple Importance Sampling" and haven't gotten this error since. Also jobs that would get stuck at around 85% now actually complete.

 

Where can I download that from?

All joking aside, I just got the same error message, after the progressive GPU lightmapper falling back to CPU. My GPU has 8 GB Vram and i have 64 GB RAM installed, so I think either I or Unity must be doing something wrong.

I figure it's the former, but I have no clue, any hints?

 

What does an error code 1 mean? Or better, where can I find a list of errors and their meanings? Thanks!

 

Thank you for taking the time to reply!

Please notice that I am getting this error working with 2019.1. But I tried with 2019.4 and it works, so I guess it was a bug that you already solved. That's would explain why I find so few results when looking up on how to solve my problem. Given that 2019.1 is no longer supported, I guess you don't need a bug report. But thank you!

I will reserve a day to finally sit down and port my project!

 

thanks man.
