Emission not working on some objects

[SVITAdmin]

OK. I feel like i've tried everything and i'm ripping my hair out. I feel like i'm missing something obvious.

I have a high poly scene (26 million poly's. It's a car scene made with an actual CAD model.)

I have to make the "mood lighting" inside. So far i have no issues until attempting this.

Some of the mood lighting works with an emission texture i created. Other objects do not work at all. They show up as lit in the live renderer, but in the Picture viewer render they emit no light and show up as typical gray colorless objects. They are all using the same emission material. (which is a texture emission using RGB values).

Things I have tried:
- making a new emission texture
- making sure normals are pointing the correct way
- making a new object and putting the material on that

Nothing seems to work. Yet in the Live render they work fine (which doesn't help me)

Am i missing something obvious? Did i hit some mysterious emission limit that im not aware of?

I'd post the job, but i cant for NDA reasons.

TIA

could you try with a low poly model? octane has 26 millions polygon limit. I suppose that's it. also check vram and texture amount of used

Thanks. Actually, i just looked and managed to bring it down to 20 Million polys. I forgot that I just took out some non-essentials last week.

It's barely using 3Gb. Running my 4 Titan rig.

I was able to copy and modify some of the lights that were working and place them. I'm still not sure what the deal is here, but at least i think i found a workaround

vram is not only limit. Also textures has own limits in their category as grey8/grey16 and rgb8/rgb16. Please be aware of.

Try inverting the normals, worked for me
