I have a question related to shaders. I created a game in which I added a shader; it works fine in web mobile and Android, but in iOS it gives an error during rendering.

I’m just learning how a shader works. So, I just copied from the built-in sprite effect file to mine. Now, back to the issue, I think, only “cc_matWorld” is used from #include <builtin/uniforms/cc-local> If I commented both of these lines, there were no error. But, everything stopped working as intended.

Hello, so my issue is such, I have made a shader that causes a UV distortion in the fragment shader, to simulate “flame-like” effects at the edges. There are two variants of these shaders, one where the distortion is dependent on cc_time[0] i.e the time elapsed in seconds when a game is running. 1.0 - newUV.x), min(newUV.y,

Hello all, I have a shader that takes the alpha value of one texture and applies to a sprite frame. I prefer to go this way so that I can have a gradient fade to transparency… the mask component uses the stencil buffer and isn’t set up to use alpha blending and therefore cannot utilize the gradient of alpha values.

I export the rendered terrain from Blender as a RGBA image but with alpha value set to depth. The custom terrain shader uses the z-channel to draw water in lower areas of the level. The graphics backend rewrite took a while. However, the situation is now good. Interactive elements will be placed using the in-game editor.

x is that, several times, sprites are separated in many nodes in order to be animated or assembled. If a shader is applied to them, or if transparency is changed, the effect is applied to every node individually, given they each do it in their own draw call. accum/max_dist); if (accum < fade_margin) { alpha *= max(0.0,accum
