hdri sky

[reneweicker]

hello,

 

I´m trying to use a dosch hdri for IBL, but however the sky appears gray not blue!?

I use a spherical map in background channel, also in the other channels exept of illumination.

 

So where´s the mistake? Isn´t it that simple?

Could someone help me?

 

thx

Are you setting a higher multiplier than 1.0 on your VrayHDRI Map?

I made some quick renders with intensitiy on 1, 10 and 50 (backround channel)...it´s getting lighter & better but not as blue as shown in the dosch preview. please take a look at the attachments.

hmm... What's your camera like? Do you have vignette on? Try a very straight forward setting of: F = 11 or 16, ISO = 100, Shutter Speed = 100. Vignette, off, exposure on (obviously), and set the white balance to neutral.

 

Also, try placing the map (start back at 1.0) into a vray dome light instead of the environment/background menu. As long as the dome lights had "invisible" un-ticked, you should be able to see it. You can also drop a jpeg of the image (set to spherical) into the Environment overrides for GI and Ref.

 

People also supplement the direct lighting with a sun on reduced intensity, but you should be able to get this working without that.

I set the camera setting like you said. Intensitylevel 10 in background channel, cause I don´t know how to map the dome sky (it´s maxwell not vray...) it doesn´t seem to have a map channel...or I don´t know how to manage it.

 

This guy had the same problem .. http://forums.cgarchitect.com/26601-hdri-skies-vray-sky-rendered-greyish.html .. but with vray. So, is there a similar button/checkbox in maxwell?

I am thinking this almost certainly has to do with gamma settings. What software are you using? Adjust your gamma in Maxwell, and/or adjust your bitmap gamma settings if you're using some other host software like 3DS Max.

 

EDIT: To be clear, is this Maxwell or Vray?

This is my fault. I use the "Today's Post" category instead of searching specific forums. I'm sorry to cause confusion. I need to be better about checking the topics before I jump in like I know what's going on.

 

The category is Maxwell. I brought up the VRay business.

No worries Corey, I can understand how you're subconsciously longing to be involved with a superior rendering engine... XD

@ Matthew, you are right.

 

I decrease the gamma value in Maxwell to 1.1 and everything is fine. blue sky.

 

Thanks a lot!
