Two of my recent shader toys display just black on iOS Safari (no compilation errors), while a separate iOS app shows them "okay" (some bugs, but at least not a black screen). https://www.shadertoy.com/view/clXXDs https://www.shadertoy.com/view/MfyXzV
Nothing crazy, pretty simple, but using feedback for TAA accumulation.
@BartWronski A good 10–20% of all Shadertoys I see render just black on iOS Safari. Haven’t figured out what the cause is, but know that it’s not a rare case!
@demofox interesting, will give a try to tweaking:
if (iTime > 0.1 && iMouse.z < fragCoord.x) {
col = col * 0.02 + texture(iChannel1, orig_uv).xyz * 0.98;
}
otherwise it initializes the buffer, but maybe the time is too late because of the compilation or something along those lines?
@BartWronski it would be great to get a pix or renderdoc capture wouldn't it? It seems like they (browsers) sometimes have support for it, but then remove it, then re add it in a different way. It makes it real hard when it's so opaque, but it also forces us users to get real creative with debugging, which is a nice skill to have after acquiring it tbh 😂
