Bakery - GPU Lightmapper (v1.96) + RTPreview [RELEASED]

That's a huge world indeed! What are these dark spots between the city and the terrain though?

 

Yup I was pretty worried about the size at first but your asset came at the right time lol. That black stuff is some stuff being out of LOD level and it's not showing anymore. Under those objects are black shadows which will never really show in the game because no one is that far from the objects in the actual game.

 

this plugin is awesome ... seconds against of hours !!

everything looks good ... skylight and directional light are amazing ...
but i can't get good results by point and mesh light ... unexpected bad lighting results :[
i hope on next release , we able to using native lights natively ;]

 

Bakery lights are better in most ways to Unitys native lights. Do you have an example of what are your bad results? Have you tried increasing intensity, and toning it down with the post processing stack? The denoiser needs light to work with.(or try disabling the denoiser to see what it actually generates)

 

solved :]

but i have problem with non-static [dynamic] objects that does not affected by bakery lights!!

here is an video that i baked [just in 20 sec!! **Awesome**] an interior smple scene from Archvizpro 1 that converted to HDRP ...

the gray spheres are non-static ... not shadows ... not direct lightings :[

 

Hello again...

Starting to get a few 'halffloat2hdr error: 5' errors now mostly baking light probes. I find if I completely remove all the temp folders, and the hidden !ftraceLightmaps object that is placed in scenes and start the whole process again, this error will go away.


This error also comes up when baking probes...


What I found was that it occurs if you try to bake probes on a scene that wasn't the last scene you baked lightmaps for.


Otherwise, I'm finding it almost impossible to perform a successful LProbe bake now. It will almost always fail with
'
Failed to unload 'Assets/Bakery/_tempScene/LightingData.asset'
'

The typical scene we're baking on ....
- A dozen or so scenes
- Thousands of Gameobjects to be lit
- Hundreds of light probes

Sorry I can't send over the scenes, but I can try to reproduce it in a non-project scene

 

Looks good! Good job!

 

your welcome
but its just a test to showing some lighting problems !!

 

Impressive!

Dynamic objects are only affected by probes and Unity lights, yes. You can use mixed lighting to integrate them into the baked scene:
- Add Unity lights to Bakery directionals and points (the ones you want to be semi-dynamic).
- Enable shadows on Unity lights.
- Press "Match real-time to lightmapped" on Bakery components to copy the values into Unity lights.
- Enable the "Shadowmask" checkbox on Bakery components on lights you want to interact with dynamic objects.
- Enable the "Bake to indirect" checkbox on lights you want completely static (not affecting dynamics).
- In main Bakery window, set render mode to "Shadowmask".
- Bake.
You should get the same baked lighting, but dynamic objects will also properly cast shadows. On top of that you get normal mapping and specular from Unity lights without paying for real-time shadows from static geometry (they are still baked).
You can also try with "distance shadowmask" checkbox on and off. When it's off, dynamic objects will cast shadows that mix properly with baked lighting, but won't receive baked shadows. When it's on, shadowmasked lights will work as dynamic close to camera but fall back to previous mode when your scene's shadow range ends.
This is how mixed lighting works in Unity - having Bakery components only equals to using built-in lightmapping with all lights set to "baked" mode.
BTW take a look at the example_shadowmask scene that comes with Bakery.

Interesting. The meaning of this error is that it failed to save a HDR file (no disk space or something else?...).
The more interesting bit is that halffloat2hdr is never actually called during probe generation - only during lightmap rendering. Are you 100% sure it happened after clicking the Render Light Probes button?

OK, now that seems like a more clearly reproducible bug - looking into it, thanks.

Are you sure that's exactly the text? I don't have anything like that anywhere, meaning it's Unity's error. Apparently happens when I call EditorSceneManager.UnloadSceneAsync (?). Can you show me a few records in the console before this error?

 

thanks for your reply ... but does a plan to fully support dynamics on next releases? or is it possible in the future?

 

Shadowmask mode is the way to go - re-read my reply and try it

 

well ... i think this method is working with legacy light ... not HDRP lights ...

this is before adding HDRP Point light:


and this after enabling HDRP Point light [matched with bakery source]:
this is disappointed :\

 

Use the shadowmask checkbox! And shadowmask render mode. Go and check the example_shadowmask scene! Read the manual, there are so many pictures! It works, but you are not even trying

Also maybe read Unity docs first: https://docs.unity3d.com/Manual/LightMode-Mixed-Shadowmask.html

I'm pretty sure ArchVizPRO did post pictures of him using shadowmask + HDRP earlier in the thread.

 

after shadow mask:

 

You scene looks like it's being lit by a shadow-less real-time directional light though. Why is that? Testing the dim spot light is hard when everything is dominated by the directional.

 

this is whole scene:


also i tried to adding an HDRP light to spot light and match it with bakery spot [without shadow] after baking:


and then after enabling HDRP light shadow:

 

For HDRP I think you need to enable shadowmasking explicitly, and for some reason this checkbox is off by default (also check the same checkbox in "scene view" section):

 

i tried that ... nothing changed :\

i think needs your genius solution for Bakery on HDRP !! :]

 

My mistake, it happens during normal baking.

When it occurs again, I'll grab the rest of the errors. And yes actually it seems to be a Unity side thing.

 

Well it does work... Maybe ask ArchVizPRO if he had to do something extra.
Did you try the example_shadowmask scene? Does it look right? There are dynamic capsules in a static baked world, and all that works in HDRP.

 

ok ... thanks for your response
but Archviz interior just model and texture ... nothing special else!!

 

He was using Bakery himself, inclduing converting one of his scenes to HDRP.

 

you mean Archviz interior 6 that used for VR?? that one is legacy and not HDRP ->> https://forum.unity.com/threads/bakery-gpu-lightmapper-v1-3-released.536008/page-10#post-3613510

my interior scene is old legacy that converted to HDRP ...

 

@guycalledfrank

and another bug ...
needs to baking Reflection Probes Again when restarting unity [Bakery 1.3 + HDRP + 2018.2.10f1]

 

Hmm that shouldn't happen. Reflection probes are rendered by Unity itself (Bakery doesn't do that - button is only for convenience) and are saved to LightingDataAsset as usual. In fact pressing "render light probes" in Bakery is exactly the same as clicking it in the Lighting window. Are you sure reflection probes disappear after you reopen the scene? Maybe you are doing something else after they are rendered and before closing Unity, like rendering light probes?

 

nope ... if press bake button of reflection probe, the unity's progressive lightmapper starting and everything of bakery goes to destroying!!

yup ... reflection probes are exists but without any data.

????
definitely i saved the scene before closing ...

 

Do you have any LightingDataAsset assigned in your scene?



Weird assumption, but if you create some light probes somewhere, render them AND reflection probes, does it work?

 

where is this option?

 

It used to be in Lighting -> Global Maps, but since Unity is rearranging all the windows with every version, I can't find it in 2018.2. Anyway, thanks for reporting - will investigate.

 

well, seems that this awesome plugin really needs to be refreshed

 

In any case - try creating light probes and rendering them (just to initialize LightingDataAsset) and then rendering reflection probes - that should work. I'm suspecting the situation you are having is because the asset is not assigned to the scene.

 

i tried that ... but in this time the data of reflection probes is an pure blue color [env. color]!!

 

well ... i changed the reflection probe type to realtime and now its ok

 

Did you try pressing the "update skybox probe" button?

Glad it works, although it's not the best solution performance-wise.

 

1. Hi frank, can I turn off backface GI of some objects? -- saw thread before, not a serious problem, but yeah it would be the best to work as another compoent to add or so.
2. And why one prefab only recognize one material as GI metapass color to bleed, I've sent you the detail picture.

 

Currently no, but I'll try to do something about it. Not going to forget it, as I want this feature for my own project as well.

All submesh materials should affect the GI. Saw the picture, will continue in PM.

 

OK, seems like there was a bug, sent you a fix. For anyone encountering this problem, just open ftUVGBufferGen.cs and replace lines like:

Graphics.DrawMeshNow(m, worldMatrix);

with

Graphics.DrawMeshNow(m, worldMatrix, i);

Highly sorry about this dumb typo
Fix will be also included in 1.4.

 

More directional lightmaps tests and comparisons.

Reference = normal map baked into lightmap (low res, but 100% correct lighting)
Dir = standard Unity-compatible directional mode (half-lambert dominant direction)
RNM = Half-Life 2 technique
SH = Frostbite (Battlefront) technique

All modes will be available in v1.4.

 

Добрый вечер с Уралом! Наблюдайте за своим проектом и ждите, пока, наконец, не появятся карты направленного света. Ориент, пожалуйста, как долго до выпуска обновления 1.4? И второй вопрос заключается в том, можно ли в следующем обновлении переключаться между несколькими картами света на одной и той же игровой сцене?

 

Did you translate to Russian via google translate or... ?
In any case, I think it's more appropriate to use English here, or other users won't understand you.

v1.4 is coming soon. Things I need to do:
- Properly integrate seam fixing/denoising to RNM and SH pipeline (should be finished today).
- Finally design something like a "Bakery Standard Shader" that would give same features as Standard, but also support vertex lightmaps, RNM and SH. It's a bit tricky to make it work on all Unity versions and render pipelines, so perhaps a few days.
- Fix a bunch of bugs I received reports about (not sure about ETA yet).

Hopefully 1-2 weeks should be enough for all.

 

Advice: I tried make auto-baking on my server, but I can't do it without UI, because your Editor Window (ftRenderLightmap) has 5163 lines of code. I found method for "start baking", but without window it falls with error 1. If It is possible to add static method Bake(BakeConfiguration config) it would be great.

 

Bake is a coroutine:

IEnumerator RenderLightmapFunc()

It interrupts itself from time to time to update the progress bar or wait for Unity to perform some action (e.g. unload a scene).

Can you try running it like a coroutine?

 

[Feature Request] it would be great if be available an auto algorithm [nVIDIA Based] to generating and optimizing UV lightmaps automatically

 

I think your understand what I tried to do. But It works proreply only if Editor Window opened
(my class)

(method that i created in ftRenderLightmap)

(Error with closed window)

 

If ftRenderLightning already opened It works as expected. But becacuse your code style without throwing exceptions, I can't properly handle an exception and relaunch method (I can, but It's bad practice to rewrite your plugin, because I want to update it without additional work inside your code)

 

Sorry, I didn't understand your request exactly. Optimize UVs? Optimize lightmaps? Optimize how?

Hmm, I see. I suspect it's because opening the window forces Bakery to load bake settings into static variables.
What if before baking you manually call OnEnable()?

 

i mean an function on Bakery that analyzing allof lightmap UVs and generate lightmap uv for objects that don't have it or optimizing it for best baking results ... but nVIDIA based

 

Now I'll write workaround for my purpose, but It would be cool if in future you'll create a static method for launch baking with custom configuration

 

I'm not aware of any nvidia-specific UV unwrapping algorithms unfortunately. Generating optimized UV layouts is not an easy thing. Take a look at this guy, he is developing a pretty cool unwrapper, and it took him many months to get there. I'm probably going to buy a license.

Noted. Shouldn't be too hard to add.

 

or something like as Generate Lightmap UV on Unity FBX importer , but nVIDIA Based [ CUDA probably ?? ]to making UVs much faster
