Using Unreal Engine 4 for asset rendering.

It is not step by step tutorial how to setup your asset for rendering in Unreal Editor 4, but more of a help to get idea how simple  it is. UE4 options/buttons are self explanatory so I won’t be writing that ‘point light’ button is placing point light on scene :).

I used Unreal Editor only once before, few years ago (it was UE3 back then), but only for brief amount of time, so you could say I’m new to Unreal Engine 4. I decided to try if, new Unreal Engine 4, with PBR and advanced camera post-processing, is good for asset rendering, and I mean no ordinary lowpolly asset rendering, but for hipoly -2 milion sculpts with vertex color data out of sculpting software. So I downloaded new free UE4 from here, and quickly chewed through some build in tutorial. I have to admit UE4 is very easy to use, everything is well designed, easy to reach.
You want too add light? Just use panel of left.
Import your model/texures? Just right click on ‘Content Browser’ (bottom left panel)  ‘Props’ folder, and choose -> new asset -> import. For 2,4 million triangles sculpt with vertex color data it took around 1-2 minutes to load.
Here is how my scene looks, with 2 point lights, one environment light and camera:

You can see it is pretty basic. All the postprocess effects are binded to camera. So when you place one on your scene, just select it and go to bottom right panel with all the settings for bloom, flares and stuff.a

The most complex part is setting the material, especially if you are not used to node based workflow. But you can click on the flashing icon (I gueess it flashes only on fresh installs) on the top right to get some quick tutorial how to setup your material. As you can see, on image below, I could use vertex color data, but I decided to go with white.

So the most important question is, where is the render button? Well it is hidden in the corner of 3d view:

Then you will see this box:

However at the time of writing this post, renders are broken – they tend to have way to much bloom, flares. They simply do not match what is on your screen. Hopefully this will be fixed. In a mean time I just used ‘print scrn’ key on keyboard. But before you do, you may want to disable all the gizmos – with ‘G’ key, and go to fullscreen with ‘F11’ key. Both options are available from the same menu, where ‘high resolution screenshot’ is (see 2 images above).  And here goes the results:
