Title: HDRI sky shows too dark
Post by: distroe on 2014-10-05, 21:19:39

 Good evening everybody,
 I am a beginner in Corona. I am trying to light a scene with HDRI image, having no other sun in the scene. Althought the lighting in the scene (the prism and the green tree) look satisfactory, i don't like the sky being almost black as the source hdri looks normal.
 The HDRI is mapped in the Environment tab in a VrayHDRI map. Please help me.
 Thank you,
 Dan

Can you show how Render>Corona settings>Enviroment tab is set up?

Hi.....why are you using Inverse gamma value=2.2 in vray HDRI.

 Hello and sorry for the delay.
 Here they are my settings.
 I did not used hdri in bitmap and used vrayhdri instead. Is this the source of the problem?

 Best regards,
 Dan

Hello again-----if you need contrast between light and shadow. set Inverse gamma value=.75 to 1

.75 or .8 are ideal in most of cases.

In environment tab, enable use 3d max settings[environment tab]. Now press 8 and you will get 3dmax environment window. now drag hdri material slot into environment. see attached image.

Thanks.
