Keyshot 3.1 : Realtime Environment Editing

With the Keyshot 3.1 update installed, here is a little demo of another brilliant feature built right in to the software.

Have you ever got the preview render running and wished you could just make some little changes to the HDRI map you are using? Well now this is just a minor step in Keyshot 3.1

 

The Process

So we’re up and running, but I want some colour in there, rather than everything being sterile white. Hit the edit button next to your environment image path.

 

 

The editor window for the HDRI has two tabs. Adjustments allows you to colourise the HDRI image, as well as tweak brightness and contrast (more on that a little later). The Pins tab is where you can add new illumination sources to the HDRI environment.

 

On the pins tab, add a new pin, and you’ll see a locator handle appear centred in a bright circle. Crucially you will see the real time preview render in Keyshot update to reflect the new light source you’ve added. You’ll have the default values of 0.5 for fall-off (how sharp and harsh the edges are) and 2 for brightness. The colour defaults to white.

 

Here I have adjusted the pin by dragging it to a new position (in this case specifically to be reflected in the watch glass to highlight it’s presence) and changing it’s colour to a pale blue. I also brightened it to 3 and adjusted it’s radius to be a little smaller.

 

Now I have added a rectangular pin, coloured yellow to contrast the blue I added before. It’s worth noting the enabled check box, so you can switch pins on and off to adjust and see them individually for fine tuning.

 

 

Here I have adjusted the underlying HDRI content, toning the brightness down from 1 to 0.25 and upping the contrast from 1 to 1.5 to get more over all effect from the newly added elements. You can incidentally set the brightness to 0 which will then make all the previous existing HDRI elements black, leaving only your newly added pins to provide lighting.

 

Once you are happy with the changes you have made, you can save your newly adjusted environment map as a new image, ready to use as and when needed in the future. It’s as simple as that.

 

All done!
