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

Portal go "bleem"! @playcanvas #shaders #affinetexture

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

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

@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!

@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.
