Luoshuang's GPULightmass

[dustintinkler]

Any idea why im getting banding on the dresser on the left and a strange circle artifact on the back wall? It isnt there when in using primary GI samples 16 and secondary Gi samples 8 but gets worse as i raise them to 32x16 and 128x64 respectively

Are you using compression for lightmaps? (world setting - lightmap card, checker box of compression) Normally much better results are without compression.

I have no idea about the problem my code does exactly i said, treating all stationary skylights as static

Well, thatt's odd, then...I guess it must be something to do with the skysphere mesh then, behaving differently under static vs. stationary? It is set to Movable, so I would kind of expect the opposite behavior if there were something wrong with the mesh or material settings...

Yep! you were right. I had separated this room form my original scene and forgot to check off compress lightmaps. thanks for the reply.

check to make sure your material is set to unlit so its not affecting lighitng, also make sure your material is not two sided and that the normals are facing inwards. there is an inverse sphere mesh in the engine content that i usually use for my skies.

While the newest testing Prometheus is missing a lot of features, it should work with LOD/HLOD though

What is prometheus? Oh and how come the front page still says

• Ray hit rejection by LOD/HLOD hasn't been implemented and you may see black splotches where lower LOD meshes poke out.

Pretty sure I did all that but will check again, thanks!

Hi Luoshang. Prometheus didn't work on my spec: win10, GTX1080 and nvidia creator ready driver 419.67 or did i miss something?

good people i saw GPULightmass once working in my PC with gtx 970. with extreme quality and high settings it took less than an hour.and that was it, now it takes a day to built light of the same scene. I've Formatted my PC and re-installed everything. it took 4 hours to build the scene and back to insane hours again. please help

it might be a driver issue. try another versions or if you havent install creators driver yet also try it.

First, this script is incredible!!!!
now I have noticed that images are darker than compared to regular lightmass. I can fix that increasing the GI in post but, is that the way to work with this??

Second, I noticed that glossiness display different, like way more glossy than regular shading. Someone else also seeing this?

thanks for the prompt reply.

im new please can you explain to me by saying another driver where to find it and install it. same apply to creators driver. please take me step by step.
