Super proud of this interior, in this case I had to redo most of the floor and ceiling geometry to make the interior work, since the time was tight I did it in just 1 day so I could texture all the interior in 3 days (+1 day for graphics)

Just published my Trim Tool to artstation for Free, just in case anyones want to use it! I made this tool to help me create quicker trims. Back on my old job we had a similar tool, but it was super slow and way more complex, and always wanted to create my onw ;)

about to upload this free trim tool for Substance Designer, hopefully someone will find this useful :P It's a real time saver! And super easy to use

Today I started *another* free tool for Substance Designer.
This is a TrimTool, I wish it came by default in Substance. In my old job we used to have a very similar tool (but with a more complex UI and not as optimized) and I always wanted to improve that specific node 👀 something that u missing?

Tough week, so I decided to spend the day drinking coffee and watching YouTube while playing with substance designer, got this material quite fast!
It's refreshing to do a material with no objective or direction, still lot of polishing needed, it's a quick pass

The blog post is hidden on my profile and it was very difficult for people to find, so I decided to include the link inside for the full blog aswell ;)

I just wrote a blog about my Physics System implementation in Substance Designer! It's a wood introduction to the more advanced workflow of the Pixel processor and data management.
I know this kind of post is not for everybody, but any feedback is welcome!

I made more adjustments and an extra test to my Physics Simulator made 100% in Substance Designer, and I think I will stop polishing it any further. I will post an artstation blog to talk in detail about the techniques used here later today!

I fixed it! This phyisics simulation was made 100% inside substance designer and it was the most usefull thing I ever made. Is it worth for material creation? No xD but I needed to solve a lot of challenging problems that it just poped up my skill with the most complex part of the software 😁

proof of this working with more complex collisions

Got more advanced collision detection on this Physics Simulator made 100% in Substance Designer, for the collision detection I'm using a pretty cool technique to compute the bounce trajectory, its not "physicaly accurated" but it works with any collision shape and its quite natural.

You can encode data in Substance designer using a color map. Using rgba channels for information isn't new to most of us, but merging rg and ba to encode 2 variables instead of 4 allows you to do incredible things.
You could store 2 huge numbers or as I'm doing now ->

This is a cool visualization of the encoder.
My green color is representing an speed of (0,0) and after the Velocity update it changes color to blue, it may seem the exact same color as acceleration but the bits of information are slightly different and changes A LOT the outcome

This is the node that computes the change of the speed based on the acceleration.
It seems complicated but the red and yellow color are decoding the speed and acceleration into values and the black is encoding again the new speed to output that

Since everything here is simulated you can change the initial position and speed and now it also moves in the x Axis! ;)

Update on my Substance Designer simple physics simulator (long name) Now the ball has gravity!
It seems just a simple offset but I'm calculating the velocity and acceleration each frame and processing it through vectors and encoding the data in a color map to evaluation
Bouncing is the next stop 👀

I'm attempting to create a very basic Physics simulator inside of Substance Designer, and I'm doing the most basic thing: a bouncing ball
So far I've faced some challenges such as encode all the data in color values! Here I encoded an acceleration of -9,8 in the Y axis into a color

Also Implemented the Extended Difference of Gaussians in substance designer, in this case I keep more than just the edge but it's better for some cases!

This is the cute pixel processor to achieve the Matrix multiplication, sadly there is no good approach for Matrix multiplication bigger than 2x2 :v But the good thing is that both use the same, just changing the matrix parameters
