Baking with GPU Nvidia

Hi everyone,

I am new to unity and this is my first post. I am building a scene and it is baking with my CPU (i3-4170), it is taking currently 55 hours to finish it, but I have a GTX 1070, how do I use my gpu to bake?

I tried to find an answer but i just finded a plugin GPU Bakery, unity doesnt bake with GPU natively?

 

You cannot natively GPU bake at this time.

 

thanks for the reply LaneFox.

I think i going to buy the GPU Bakery, because my CPU is too weak for this.

 

Sorry for taking so long to respond, i was working on my own to try and solve the problem.

Well i made some progress, i tweaked with the lightmapping settings and now my scene it is baking in 3 to 4 hours.

My problem now it is that after the bake, unity does other things, like visibility, clustering, etc...
This other things it is taking really long to complete, like 4 hours after it finish the baking time.

I have many questions, first question: all my lights are realtime, so it is really necessary to generate light? if i don´t generaty light, the light inside of my houses arent equal in my prefabs (i am putting images of my scene here in the post, all the images are without generate light)

Second: it is my scene too big? my idea it is to build a city, but one block is really getting difficult to work with the light, i am a noob in unity, i thought it was possible to build a city in one scene only, i guessing that i tought really wrong. (image of whole scene below)

Third: my lightmapping settings are good? i mean, it will look nice? because i have done some baking and inside the house, some prefabs (specially next to 90 degrees curves, like to walls making 90 degress with one another) the light still stranges.

Final question: the visibility and clustering it is taking really long time, like 4 hours, unity some times even crashs in this part of the process, and i have increased pagefile in windows because my 16gb ram wasnt enought, it was giving me a error of insufficiente memory, is this normal?

Well i guessing that i am doing something really wrong, or my scene is too big or i build it wrong, If you guys have any tips for me, I'll be very grateful.

 

Thanks a lot kristijonas_unity,

I will try to use baked and then realtime to see what will look best, but i think i will choose realtime because my player will do not have shadows if i choose baked only.
I will look the toturial too.

Thanks.

 

Honestly, that would look identical with realtime lighting and realtime gi, which would just involve a small preprocess step. Baking is really only for if you really need performance on lower end systems.

Thanks for the help guys, I am doing some tests here, when i finish i will post if my problems are solved.

In performance matter, i am buiding a game for desktop, my GTX 1050 TI is running this scene in an average of 30FPS in 1080p in ultra, and every light is realtime, so i think is ok.

 

Hi everyone,

After a long research and testing, i think i am finally getting there, I tested the realtime, baked and mixed light modes, the difference in the scene wasn't so noticeable between baked and realtime, but how i am targgeting high end desktop or maybe a ps4 and xbox one in the future i will go with realtime lighting.

I optimized the scene so small and dynamic objects doenst need to be precomputed by unity; set open doors like floor, grass, trees etc to render in verylow settings and the rest of the scene to render in medium lightmap parameters, with the indirect resolution of 0.5.

With this configurations i was able to complete the row generate lighting in about 80 minutes, much better now, and the quality of the lighting in the scene is good.

I just have one problem left reggarding the ilumination, and i thing it is because of UV charts or maybe clusters. My problem is that the light calculeted and applied over my prefabs, sometimes doesnt match the prefab by its side, and in uv charts view mode, i can see that the charts is distorting in some prefabs, but changing the UV max angle and distance did not solved it, sometimes it helps, but still different.

anyone knows how to fix it or maybe a link to a tutorial that may help me? i am putting printscreen of my scene with this problem below (also my scene now it is at night, i think i will build my game in night time)

Thanks for the help guys, the tutorials links was very usefull.
