CoronaNormal flip defaults according to 3dsmax preferences

[Bzuco]

Corona 1.5, 1.6. I didn't test this on older releases, maybe this issue is here from the beginning.

[romullus]

Yes, Corona reads normal maps like that from the beginning, and no, it's not a bug. 3ds Max expects normal maps to be -Y and Corona for 3ds Max, complies with that.

[Bzuco]

Could be the Y inverted as default...so we dont need set that value everytime I load some normal map? :)

[romullus]

It was inverted already for a brief time, but then returned to what it is now and i hope that it will stay that way. I work with 3ds max only, so i always take care that all my normal maps are in DirectX (-Y) format. If Corona would decide to go against its host app's standarts, then i would have to flip green channel everytime...

[Ondra]

what if corona took the defaults from the 3dsmax global normal map settings? Would that be OK?

[romullus]

Actually that might be good idea - that way both sides should be happy :]

[Bzuco]

Set default state to checked for Flip green checkbox component would be enough and maybe small text hint with info about 3dsmax is working with -Y as designed.

[Juraj]

Half of my normals maps are from Quixel which require Y-flip, and other from Allegorithmic Source, which don't.  (yes, each app let's me do different export, but then I would forget which individual map is which so I adhere to global setting)

Damn standards :- ( Would be cool if there was automatic detection possible just like with gamma. But maybe that depends too much on visual perception to be easily coded.

then the other half of users would get pissed :/

..so there are only few options:
1. let's voting :D
2. some corona.ini file with user settings
3. maxscript

Code: [Select]

n = CoronaNormal()
n.flipGreen = n.addGamma = on
meditMaterials[medit.GetActiveMtlSlot()].texmapBump = n
