Transparency is handled differently across render engines and file formats. While a PNG, TIF or GIF file can contain transparency data, a JPG image cannot. DAZ Studio’s Iray render engine can’t handle transparency data embedded in such images and requires the use of a special Opacity or Transparency Map. This might sound a little confusing, …

When you’re done with UV Mapping in Blender, you may need to save out a template of your hard work so that you or someone else in your team can get to work on some fabulous textures. In case you ever need to save out such a UV Template, head over to the UV Editing …
Something that wasn’t immediately obvious to me is that Unreal Engine saves its own file format under the hood. For example, a prop or audio file is not stored as .OBJ or .WAV, but as .UASSET file. Perhaps it’s just a wrapper that stores binary data, or maybe it’s some other kind of magic. Be …
I’ve just learnt about a nifty mechanism to change parameters on a material node in Unreal Engine. The niftyness lies in the fact that when we convert static values in the material editor into parameters, which them become the equivalent of public variables that are accessible from other parts of UE4. It sounds way scarier than it is, let me how you how it works in detail and step by step.

There’s a slightly weird terminology I keep hearing in various 3D applications. Those terms are Yaw, Pitch and Roll. I have trouble remembering which one is which, and which one is related to what axis in 3D space. I’m more used to the Euler notation system, and the only one I can remember is “roll” …
I’ve always been marvelling at all the little moving background items in video games. Most trees, grass, plants and such foliage appears to move subtly. How do they do that? Perhaps it’s a wind node? Surely that’ll eat up huge amounts of resources.
I just found a computationally cheaper trick to do this, namely by adding this effect to the plant’s material, thanks to a video by MetalGameStudios. It suggests that we can do this in two ways, both of which are described below. In either case, open the material of your object to proceed.

I’ve been on Patreon since May 2018 (I think), and I really like it. It’s a great way to support me and my projects ongoingly, and I’ve been able to invest your donations into anything from software to hardware, as well as coffee – all to improve my output and make the world a happier …
The EPIC Games launcher is a really handy tool from anything to add content into your projects or to browse marketplace assets. It has this annoying habit of closing automatically when Unreal Engine or a game of your choice is running. This might be fine for gamers, but I find myself frequently re-opening it once …
