# Tech Art Fundamentals tutorial series

Thanks for the feedback Oskar, I really appreciate it

I did wonder about the splitting of the videos. I mainly did it because originally they were going to be going up on another tutorial company’s site and that was required. So I just uploaded as is.

Also, doing the split allows me to upload one at a time so everyone isn’t waiting around as long.

Maybe I could compile into longer videos and uploads those once this latest round is all done, I’ll have a think. Can’t hurt to try.

PS. net video will be up in about half an hour

Yes, I think it won’t hurt to put them again, as a separate combined video

Cool I’ll try and get round to it soon.

Here’s the latest video which resolves the cliffhanger…

Thanks for putting all these together!

Dude these are awesome! Thank you for making them!

This is great stuff! As a beginner, I often fell into the trap of tutorial videos that followed the “click this, then that” path but found myself at a loss whenever I tried to figure out the “why” behind what they were showing me. This series should have been my first stop and I will encourage others to follow suit in starting with the fundamentals before jumping into the heavy stuff. Thank you for your contribution and I look forward to seeing more content in the future! You’ve gained a subscriber today!

Regarding Part6
For the brush material: at 5:46 you used a 4d vector to get the uvTransform then masked out the red and green channels. Out of curiosity, is there a specific reason to use a 4d vector instead of a 3 or 2d?

There is no 2D vector param in Unreal materials. However, you can use 4D to pack a full transform: ScaleU, ScaleV, OffsetU, Offset V.

Ah, I see now where I was getting confused. I wasn’t specifically looking for a 2D vector parameter, instead I was thinking of using just a 2D vector there which I guess would still be possible but not very practical?

Ah I didn’t even think to use the B and A of the vector 4 for offset parameters. That should cut a couple parameter inputs from my material instances in general. Thanks!

Yeah that’s definitely a good idea. I dont really concentrate on final optimization in the tutorials as I think it gets in the way of understanding and simplicity. Maybe I should wrap up with an optimization and performance video for each topic.

Might be worth to at least mention a few things about how to optimize it and the performance of it. Figuring out things like that was (and still is for me) one of the hardest things to learn when I started with fx, so always good to give people an idea about it when possible.
