cool, it reminds me of a building in my city São Paulo, it's called "360"

All right good

There is no problem with this element

Does this still work?

This is a prelude to the creation of the MegaTower in Simcity COT

In fact, good news !! For my futur assets, i take care with LOD illumination file and adjust them like i do for this one
Thanks for your comments, i can progress with them !!

Good news. Your update did the trick after all. Appears that I failed to reload the updated asset yesterday. I probably forgot to quit out completely and then restart the game, because today the over-illumination effect is gone. Many thanks! :)

If you can't reproduce the same problem, then I suspect it probably is a mod conflict issue on my end. Not running either "Clouds and Fog Toggler" or "Daylight Classic", but I am using a whole slew of other mods - most of which should not affect rendering. but one never knows, I suppose. I had already done some testing by turning off "No Radioactive Trees " and the "Sun Shafts" among a few others, but it didn't help. Don't have time right this moment, but I will run more thorough tests shortly and get back to you!

I can't reproduce exactly the same effect as you,
I used the mod "clouds and Fog Toggler" and "Daylihgt Cassic", I try to test the different way of them but the asset looks fine
I always built my asset with the same technics... i don't know what's appened with this one

Sadly, despite the update the issue persists. :( Can also confirm I am now using the updated model you uploaded as I had to re-plop the instances of this building I had in my city. It sounds a little to me that you are not seeing this same "whiteout" effect on your end? Perhaps, if everything looks fine on your system, then I could be some kind of mod conflict over here?

new update, i have change the illumination and surface LOD file... may be better ; )

ok, i see the problem
i may have made mistake with the illumination LOD
i take a look as soon as possible and i update it
thanks for your return !

@luminou Thanks for getting back to me! Take a look at https://imgur.com/a/4F1Hr for a pair of screenshots showing what I'm seeing in my city.

The LOD has a texture (take a look at the screen shot)
When you zoom out, details are too small and we cannot see them and looks like with wall

Beautiful asset! Very nicely done, except I'm seeing a problem in the least detailed LOD which appears to be un-textured. I'm just seeing a completely white model when zoomed all the way out. Is this something that happens on your end too, luminou?

Cool! :D
