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

v1.1 is published!
https://assetstore.unity.com/packages/tools/level-design/bakery-gpu-lightmapper-122218

 

It is worth having the option. I am using it a lot !

 

OK imported the new version in the city scene with the bridge.

I whanted to bake selected on roadmarks to test the issue with shadow cast off.

I did first accidentally delete baked light data thinking it was temp data, nevermind select and press bake.

"Exporting scene-shaded surface colors..."

I had to alt + f4 to close unity

 

Try doing the full bake first.

 

same err with full scnee bake ( ok obviously, but had to try) plus I get a terrain err when it was marked to lightmap (I can go without lightmap on terrain)

 

It's probably caused by some particular objects. Can you try disabling, like, 50% of the scene and see if it works? Then another 50%, and so on, until you find the object causing it.

 

Also notice that clear baked data will unlink the lightmap data form teh models but I'm seeing the lightmaps files still exist in the BakeryLighmaps folder.

 

Ok, but I had this scene already baked. will try to isolate the issue but I was coming for a quick test as I was doing scripting thing haha.

 

Also, the scene presets have been wiped, this may have been the cause too the texel per unit is super hight etc..

 

Oh wait, I think it's caused by object NOT having a material.

 

An option for it only appearing in indirectly lit areas would be good too.

 

TooManySugar, try to update this file.

 

There is a mesh that is pink due to lack of material, yes, may be that one is the causing thing, I did not bother casue this is a test scene, will report in few minutes

 

Or actually better try this one. I realized it could crash when you have materials.Length < subMeshCount.

 

FIXED!
you got that one super quick!
I confirm terrains unchecked to lightmap seem to trow no more errs, will test later on again the terrain as seems to be problematic, I've several in other scenes too so it may be something specific to this one. I leave while it renders for dinner as pc is totally freezed due to sucking all resources

 

I didnt run with second one but first one, but ok I will overwrite later.

 

nice. all whent fine, roadmarks now don´t drop shadows.

I noticed that tree creator leaves still project shadows as planes cany tips for nature shaders drop shadows with alpha?
I've tested some shaders las mobile difuse or a custom double sided and indeed LM are rtained. I'll tomorrow test the latest version of that script just in case something happens.

Clear bake data unlinks the lightmaps to the scene yet does not delete lightmaps, this may be the desired effect but if not ....

 

Sorry, didn't fully understand your sentence. Can you check the texture name your tree shader uses for opacity?

Yeah, the clear button is to clean up your scene, but not the temp folder. Will add another for temp.

 

Did the price go up on this?

 

Sorry for my crappy comunication skills XD.

1) I've a tree, is not placed in terrain, this tree has Optimized Leaf Material and this tree I've with scale set to 0 so it does not self lit but does drop shadows. It does dorp shadows but the tree is formed by planes

It is a unity tree editor tree.
The shadows this casts are shadows of planes without leaf transparency.
May be I should create new material and don´t use the "optimized" materials but nature-->Tree creator leaves?


2) I didnt meant the temp file folder wip (even this will be usefull). The current clear bake data does not delete "BakeryLightmaps" folder lightmaps but only deletes the connection of the scene objects with the lightmaps in teh folder

 

May be 5 bucks. Still a bargain.

 

A bit ($30 -> $35). Explained here in my old post: https://forum.unity.com/threads/bakery-gpu-lightmapper-v1-1-released.536008/page-2#post-3555487

 

I was about to buy last night but decided to wait until today haha. Good to see I wasn't going crazy.

 

Found the reason for this. Somehow TreeCreator leaves have its own RenderType = "TreeLeaf" I was only accounting for Transparent and TransparentCutout.
Fixed it, will include in the next update. You can quickly fix it yourself by going to ftBuildGraphics.cs and replacing

if (matTag == "TransparentCutout" || matTag == "Transparent") {

with

if (matTag == "TransparentCutout" || matTag == "Transparent" || matTag == "TreeLeaf") {

 

Hi, this product seems to be getting very positive reviews, congratulations. I have a question.

This is a baking asset, so can I bake Indirect Lighting only for Realtime GI with it as a substitute for Unity Lightmappers? But I realised directional mapping is not present. Also the price is steadily increasing. I want to buy it asap but please let me know.

 

Hi. Yes, you can bake indirect lighting, but it will be static (won't react if you change lights at runtime). That should be similar to how Progressive works.
Directional (the one with bump and specular) is not supported yet - but I'm working on this

 

@guycalledfrank, do you also work on objects emit correct GI that have lightmap size = zero (like Unity does)?

 

I mean for Precomputed GI which is Realtime GI and not for baking Baked GI.

 

Yeah, will do that

No realtime GI. Same limitations as with progressive.

 

By the way, thanks for your relieable and quick responses!

 

As soon as this has ShadowMask support I will buy it !

 

You can use precomputed realtime GI with Bakery or PLM if you save baked lightmaps in editor and load it in runtime on start.

For load lightmaps in runtime you can use something like this - https://pastebin.com/GayDUvQU

How its work in production you can see here:

 

Wait, did you bake separate lightmap for every type of surface color?
great music choice btw

 

At least looks like he did for each floor I was pretty impressed too. I guess he has automated the baking process too somehow .

 

No, one baking lightmap on all scene in white color material. Indirect lights effects from surface colors - it`s precomputed realtime GI with updating in runtime.

 

But you can only bake precomputed realtime GI with Enlighten. What does it have to do with PLM/Bakery?

 

Lightmaps - it`s only textures. You can load it in runtime even when Backed Global Illumination disabled and Realtime Global Illumination enabled.

 

hi man, just wanted to ask you about normal maps. I am using PBR materials in my whole game so I am kinda need it. any idea when you will have support for these?

 

Can't give absolutely accurate estimates, but I think it should be done in a month.

 

I'm researching shadowmask at the moment, and it seems like occlusionMaskChannel was only added to API since 2017.3 . I need it to set which light uses which shadowmask channel. Is there any alternative on older Unity versions?

 

I just think that you have to come out with your own logic here !
Plus, i think there is only 4 lights that could masked per texel in some precious version of Unity and more than 4 in newer versions ( I am absolutely not sure on that, but be sure to check it )

 

TBH I'm surprised there is even a publickly exposed way to achieve. That said was reading some competitors reviews and seem to have managed to add marking, and since they support 5.6+ there may be a way to do so

I was looking for post of ppl importing VRay ligthmaps and whanting to do hsadowmasking, no luck so far.

 

Why do I always get stuck in the export scene?

 

Do you have
1= terrains (they may work but to me have been problematic
2= not UV2 mapped objs
3=objects wtihout material!!! This was causing me err, dev posted fixing script few posts ago.

 

Ok, so
"occlusionMaskChannel In case of a LightmapBakeType.Mixed light, contains the index of the occlusion mask channel to use if any, otherwise -1. "

According to the link I poste the other dya:
"
In this mode, both the indirect lighting and the shadow attenuation for mixed lights are stored in lightmaps. The shadows are stored in a separate map, known as a shadowmask. When using only the main directional light, everything that's illuminated will show up red in the shadowmask. It's red because the shadow information is stored in the texture's R channel. Actually, shadows for up to four lights can be stored in the map, as it has four channels.

"

So, the

occlusionMaskChannel​

seems to be dafaulted to R one, so even if not exposed in older versions isn´t gonna work by default unless you use other channels to store the data?

Unless you've already with no luck, I think its a link worth checking because otherwise there is no much info out there
https://catlikecoding.com/unity/tutorials/rendering/part-17/​

 

I have Material for each object. All mesh have uv2. My scene have no terrain. I don't know way always show export scene. Bad mood......

 

Export scene as package and send it to the dev sure he catches the issue in a blink.

 

Also, enabling overwrite warnings in my case showed up additional warnings. So enable warnings may be you get an informative message.

 

Hey! I purchased Bakery today and I've been trying it out and I must say I'm very impressed.

However I've encountered some issues when I'm baking. It seems like alot of my meshes with negative scale turn black when baking is done, it doesnt happen to all objects with a negative scale, but for what I can tell all the objects that have turned black has had a negative scale.

We are using 2018.2.2.f1 so maybe thats the issue?

I tried searching in the forum but I couldnt really find an answer to my question, so I apologize if this has been answered before!

 

Hi, @guycalledfrank , you mentioned that you fixed the negative scale issue when the parent object is with negative scale ! Does it apply if the object itself is with negative scale only and it's not parented ( i was wondering but can not try now ! ) ?
