First time posting - been skulking around trying to find a solution to my (admittedly niche) issue.

The issue is that I want to be able to recreate the effect of the mid-90s Sega answer to drawing transparencies - aka the checkerboard/mesh/dithered transparency - in Jitter.

I've been able to create my own shader in Blender using the nodes (pic attached), and have even managed to do the same in Unity. However, I've been scratching my head a lot with Jitter and as I am not as familiar with it I've gone down many dead ends, or have stood at the bottom of (what appears to me) a rather large coding hill.

My question is would I be able to achieve the same effect without having to delve into OpenGL coding, and if so would someone be able to give me some pointers please? I'll attached my very messy patch as well.

Apols for the mess of a patch, and one thing to note, which was also perplexing me, is that the sphere seems to render on a different layer (?) until I reload the camera object, where then everything appears where it should.  Basically this is where I have gotten from poking around and internet searches.

If the answer is "yes, you need to OpenGL" then I can know to park it for now. 

Thanks in advance for any pointers there may be!

But yes, you'll likely need to dive into GLSL to get this right. That being said, here's a quick attempt at something close without any custom GLSL

Thank you so much for your help Rob! It's definitely step closer, and gives me something to work from. Also anim drive controls make things so much easier!

I put together a stochastic transparency implementation that uses a Bayer matrix as the pattern for discarding the fragments:

I hope it could serve as a starting point

Hi Matteo - this is great, thank you! Definitely another line of enquiry to get stuck in with.

Incredibly grateful for both of these responses - I was very much in the "can't see the wood for the trees" territory.

Thanks Matteo for this patch and shader! I realized I forgot to thank you for your answer at my thread on the same topic, so thank you again!

I definitely prefer the bayer style, I really like that ordered dittering aesthetic.
