Title: CoronaLight and Texmap with alpha: bug?
Post by: cecofuli on 2016-08-08, 21:36:38

Hello,
I think there is some problems with CoronaLight and Texmap with TIFF or PNG with alpha.
I'm not able "to cut" the CoronaLight the the alpha channel inside the texture.
Can you confirm?

Thanks

Ehm.. I'm talking about CoronaLights, not CoronaLightMtl.
I mean, I want to use a texture with alpha (PNG or TIFF) as a Texmap for CoronaLight.

Uncheck "Occlude other lights". This may be not be exaclty what you want but then you have transparency.


Good Luck

Ohh... I didn't know this "tricks". Thanks!  =)
Yes, this option doesn't use the alpha channel, but, I think, the RGB value.

this is by design, Corona Light does not support transparency
