Lightmap

Covin

Hi to all, in this days im trying to create a ME Scene Style, but i have problem for the lightmap.

Without lightmap:


With lightmap:


Mesh with UV lightmap:


Why when i activate the "emissive static lighting" for the "arrow", the mesh have a strange lighting effect?
Thanks and sorry for my english. :poly124:

whats wrong with it? looks fine to me.

Covin

Look at the "weird" light on the upper and bottom part of the mesh, is clearly visible the seam of the mesh model.

it looks like it might be somethign to do with the emissive light coming from the red sign. have you tried turning off use emissive in lightmass or just deleting the light and seeing what happens?

just a guess mind but the emissive light isnt doing anythign in the top picture and its definitely affecting the mesh in question.

cheers

Without the emissive light the result of the lightmap is good, but how can i resolve this problem?

tharle

just noticed you'd already identified the emissive as the problem in your op.

have you tried adjusting the lightmass world settings and/or the material settings. i dont know which setting is causing the problem but just experiment.

can you upload the package and map? i can have a quick look but i can't promise anything!

Covin

I have resolved by disabling lightmap function of the light in the middle of the scene (i have left enabled only the light of the emissive and the light on the side).

the falloff on the neon lights looks kind of odd. you would expect a bit less of an extreme falloff. also they seem to have very little effect with the overall lighting of the scene which clashes with their aparent strength.

So far as your lighting goes its very white and boring. It looks like your copying the wards, which had lots of hot/cold lighting (which looks really punchy). personally i make it a rule to not use any totally white lights

99.9% of light sources have some colour tint to them, even the sun. pure white light looks sterile and artificial.


heres something to consider.

Hi,
what program did you use????

Oniram

i cant help but laugh (in a good way) when i see this. i just showed this thread to a few friends of mine. basically looks just like the project we are working on (also ME inspired). funny that your most recent shot looks just like the layout for one of our things, but it happens. lookin good so far.

Covin

Thanks for the replys and for the link. :poly121:

Hi Covin.
Have you made sure the lightmap resolution is high enough not to cause seems?

Covin

Every mesh have a 512 light resolution, i think is good, or i have to higher the value?

r_fletch_r

that or increase the space between you're UV islands. you should be able to see things like this in the lighting only display mode.

This is the same scene but with 3 Indirect lighting bounce and lightmap res of 1024 on every mesh.
