VRay for 3Ds Red Rendering - Please Help!

[kevinmayo]

Hello,

I just starting learning VRay for 3ds Max and am having some issues with my early attempts at rendering. I have followed along with many tutorials on rendering exterior architecture scenes and think I have pretty much the exact same settings.

I was having an issue with two different scenes both different issues. In one the single HDRI dome light is completely washing out my renders for some reason. I am using most of the default settings so I don't see where my issue is coming from.

Also in another scene my render is coming out like an infrared image, but the lighting seems fine aside from that.

Here are some pictures with my settings and the resulting render.

There's a button that says "prt scrn", or print screen. Use that to take screenshots.

Looks like "Pseudo Color Exposure Control"

I think this behavior can also be related to using a non-legitimate copy of VRay.

 

As far as an HDRI washing out the scene, you need to adjust the exposure control, whether it is in the physical camera settings or the render settings.

Thank you for the feedback, I am using an education version of VRay licensed through the dongle... not sure but it seems like some of the functions aren't available to me. Though I am very new at this, only used the Revit in house renders before this.

The Pseudo Color Exposure control was the issue with the red renderings, thank you for that! I will play with the exposure controls to try and get the light to work correctly on my other scene.

Thanks again!

Great!

 

Here is the documentation for the different places that exposure can be adjusted:

 

Global Exposure Control

I think this is set in the same "Environment" settings dialog that the Pseudo Color Exposure is set at.

 

Physical Camera settings

 

It follows the same general rules as real world photography, so that knowledge is mostly interchangeable.
