Tech Art Aid video tutorials - UE4, shaders, proceduralism etc.
Hi, Recently I started recording tutorials for technical artists. Advanced topics will follow soon but I think that basic "bulding blocks" of tech art are important too ;] https://www.youtube.com/channel/UCs2RyUGngZIZYdZaQ5p2mGg Project files: https://gumroad.com/techartaid Watch the videos, ask, criticize.

Re: Tech Art Aid video tutorials - UE4, shaders, proceduralism etc.

UE4 automagically converts to DXT compression right? Could be worth mentioning color depth/accuracy and how it differs between RGBA channels. Alpha channel gets best accuracy by far, followed by Green channel and lastly Red & Blue on same level. So this means, pack your textures with this in mind so that your data which… -

That's great to know that the format works fine! Thanks so much. You got it properly. I'm not 100% sure. There should be some reason they didn't disable Static option in instances component?

Oh, was just browsing through here. Thanks for the props/share This is what Lazy Save Channel Packing actually automates for you with the colored groups :) -

A suprisingly high number of people keep asking about this :) It's even easier with LazySave, if you can use plugins - http://polycount.com/discussion/171661/photoshop-extension-lazy-save -
