I don't always have graphics bugs, but when I do they look moody AF.

Portal go "bleem"!

Today in Portal Land
One portal working nicely.
Add a second and... bleem!

[Carl Bateman @CarlBateman]

Working!
It looks like the same named attributes over all shaders.

@playcanvas Six days! Six bleedin' days! Trying to fix this!
Inverted bi-linear, bi-linear, non-affine? Nope
Quick fix was:
𝚐𝚕_𝙿𝚘𝚜𝚒𝚝𝚒𝚘𝚗 /= 𝚐𝚕_𝙿𝚘𝚜𝚒𝚝𝚒𝚘𝚗.𝚠;
but didn't seem to work.
Not the shader! Because I was tracking the wrong bloody thing--the player not the camera!

@playcanvas
The Portals implementation is coming along nicely.

Oh, wait. Oh. Oh, sherbert!

[Carl Bateman @CarlBateman]

@playcanvas
Progress with a more ambitious Portals implementation.

I’m revisiting implementing portals (as in the eponymous game(s)) in @PlayCanvas, having abandoned my first ill-fated endeavour. 🙄

I’m now adopting a mask-based approach with promising results. 🙂

Mask is top left, portal view is top right, main image the merged result.

Just discovered this beautiful series «Erosion» by British artist and ceramicist @tamsinvanessen, love the material and intricate shapes of those
